Hi! I recently replaced a broken chip in my projector (Acer X1320WH model) and I'm not sure about the placement of the big fan(s) next to the lamp (so not the small one that was cleaned in this video). Should they pull air away from the lamp and towards the outside, or towards the lamp and into the projector? Here it seems like the big fan is pointing towards the outside, given the arrow sticker we see on top of it. Is that true for my projector as well? Last time I turned it on, it smelled bad, like maybe it was overheating.....

Hi frank not sure if you can help but my benq tk800 is driving me crazy. I keep sending my projector away to be fixed but a month after getting it back same problem. It overheats and turns off after about 20mins. I changed the lamp but same issue as with the original. And BTW the lamp body is insanely hot!!! Not sure if that's normal. Everything inside is super clean. Also I am not sure if it matters but I have no plastic membrane over the lamp, maybe when they previously repaired it, they forgot to replace it? Also I can I only see two fans when I open it. The one to the right of the body near the back blows inwards and the one next to the lamp blows outwards. Is that correct.. Help please and thank you very much for your great videos. Any advise appreciated. I'm in Spain BTW

Ok second surgery and it seems like nothing boots up at all no fans nothing

This unit was really bad about blowing output transistors. I have one stored that I would like to repair. It does not like to be run at its full rated output (not even close) and it also does not like difficult loads. As long as you don't rock out too hard, it is ok. A good friend gave this to me after the third failure. It has been packed away a long time, but I do have the service manual. May start to look for output transistors, even if I settle for after market.

Thanks for the video! My Hd142x has a 4 month old bulb from projectorlampsusa and recently it started making buzzing noises. Now when turned on, it makes a loud static buzz, the bulb flickers and then shuts off. I disassembled and cleaned everything but still same issue. I've heard it could be the ballast board? Is that the entire power supply board? I've also inquired on the bulb warranty. Any advise would be much appreciated!

Learned this the hard way. Optoma HD142X now dead. Amazon lamp measuring high resistance as stated. 2nd lamp bought from ProjectorlampUSA reading open-good. But the damage was already done by the first lamp. *sigh

👌

Hey frank can you fix white lines in BenQ 1075 Prjector

My 5040UB suddenly went dark. Directly from EPSON as a refurbished. Took out the bulb. CTL 5182 is what had written on the bulb. Does it mean the unit they sold with warranty had 5182 hrs on the bulb????

Hi Frank, Crystal was a very good contact. All parts were in stock. Do you have a Service Manual for the NEC M311X / M271X /M361X I have a pile of them to refurbish.

Hi. My left-right and up-down dial adjustment is stuck. Is it repairable? Thanks!

GOOD JOB CAN HELP ME? MY AX33 REC WHIT SCREEN

The lamp on my th1060 comes on, but only for about 5 seconds then shuts off. When I double press the power button, the bulb will again light up for a couple of seconds before the fan stops. Any ideas? Thanks..

Hi I have a friend with a GT1080HDR projector that’s making a loud humming noise, how do we fix it?

So I have this very power strip and have used it for several years now. Today it suddenly stopped working. When I plug it in there are no lights. Cannot hold the button to reset like usual either. App just says device offline. I love this strip and just not ready to let it go. Any ideas what I could check or do to revive it?

Thanks for detailed information, Checked thermal fuse, it was okay but still current was not coming to Varada Max XL 12 lit air fryer .

Thanks

Hello Frank - I don't know if you are still monitoring your RUclips Channel. I tried following your steps in troubleshooting a BenQ 1080ST projector. A few weeks ago my lamp blew up (literally). I bought a replacement lamp, an Osram OEM lamp but the lamp would not turn on. I followed your troubleshooting steps on RUclips, and I don’t get the voltage readings that you get but I am not sure where the problem is. I measures the lamp and I get infinite resistivity so the lamp is good. I measured the color wheel sensor signal (most left pin) and I get a constant reading of 3.55 volts ( the voltage does not drop to 0.4 volts when I turn the projector on). The color wheel is turning. I also measured the voltage at signal to the ballast (4th pin from the right) and when I turn it on it initially reads 4.37 volts, it drops to 2.34 volts and goes back to 3.34volts where it stays (eventually it goes back to 4.38volt) Finally, I also measured the input to the ballast per your video, and I get a constant reading of 152 volts, not 388 volts what you get. So I am not sure what the issue is, can you help?

Thanks a lot for this video, had the exact same projector with same symptoms. Took it apart and there was no black tape on the color wheel. I used a piece of the black tape that some of the flat electrical bands had and it works perfect. Used little bit of skin tack to make the surface where the tape goes on the wheel just so the tape adheres better and doesn’t fall off. Also, no adjustments had to be made except zooming back in and focus.

Amazingly detailed video. Thanks so much. Made me brave enough to tackle this repair myself. I had the same smaller Amazon bought color wheel that didn’t work. But a good clean of the whole, very dusty, projector and the old color wheel is working again. Will order another OEM one to have on hand for the future. Thanks again.

Fixed my shyt lol😂

I just got my DHD 775. The image has a small strip of rainbow-like color the runs the entire height of the frame on the left 3 inches or so. It definitely took a good bump while in shipping. Does this sound like a mirror out of alignment?

Great video, and very helpful! I've got a question about the color wheels. Do they ever go bad, or need replacing? I just put 2 new OEM lamps in my DHT-100L's but the yellow just isn't popping. I've gone through all of the different color presets, but still no luck. Just testing on a white wall so that could be part of it, but I'm wondering about those color wheels and if they need replacing. If so, do you have a supplier you recommend? Many thanks!

Hey Frank, there's an extra part you didn’t need but I do, anyway we can connect so I can buy/donate for it?

Hi Frank, your videos were very very helpful for me cleaning out my old BenQ W2000 I sold to a friend that had been running for 8 years without a proper clean (and also with learning how to reach the service menu), and though that projector is now very clean and free of any visual orbs left by when my friend tried to use computer duster on it, when I run the lamp in normal mode (it also ramps up in eco but not as much obviously) it quickly goes from Temp 1 around 403 and LampOut/PwrOut/LampBlw/DMDIn around 2500-2700 (these being the targets as well), to temp 415-418 with fan speeds/targets in the 2700-3000 range. Do you have any idea what might be causing this? I am wondering if it has to do with me repasting the heatsink badly somehow, or a fan or sensor acting up maybe (though fanspeeds look like they're accurate from the readings and fan sound) I haven't torn it down again to check the heatsink, and I'm fairly sure the fans are in the right directions as I went back in and verified those. I have no idea where to find much info on servicing these so your videos have been my only source of information, thanks in advance if you have any tips

how much do you charge to fix this? I have the same issue.

Looks like this has a heat pipe cooling system. Does that part of it need to be serviced at all? I have a DHD775 coming which is very similar to this one.

I have an Epson 5030UBe that worked the day before and then the next day I have the same issue you had with the EPSON screen then grey. No menus come up. Remote and everything works but no menus will come up. So I am thinking I may have a mainboard issue as well. @FixitFrank Where were you able to find a replacement mainboard? I believe I will need to find one for my projector.

Hi, just did a colour wheel install from your video. All was great I’ve now got a super quiet projector. The only issue is the projector doesn’t respond to the remote control anymore. I can’t see that I’ve unplugged anything I shouldn’t. Any ideas. Cheers

Its good only issue is when connected to big tv screen there is alot of noise.

8/1/24. Second viewing. Still using my AX-33. Gave you a 👍at the first viewing. Seems like Sony is not as interested in camcorders nowadays. They've been pushing blogging capable pocket sized cameras with video capability. Even called it quits on the AX-700. The new A6700 has tons of new bells and whistles, but getting a decent PZ lens costs as much as the body. I'll continue to stick w/ my 33 if only because BOSS is better than all that in camera stabilization that crops the image.

Is there a tool list for this or do i just need one small Philips for everything

You are the best!

Hey Frank, this was a great video. After watching it, I'm afraid if I try this, I could mess something up. Would it be possible to send me a quote for cleaning my HT2050A?

I just bought the same projector but its making an odd humming/buzzing noise when the lamp is on. I thought it might be the phosphor wheel fan so I took it apart but now I have a feeling the noise is coming from the phosphor wheel itself... Any advice? Is it possible to replace the wheel or is it even worth it trying? Projector works perfectly, besides the noise. Any suggestions really appreciated!

Hello, Frank. I own an Optoma DS551 and am trying to bypass the SMPS and ballast. I've monitored the signals from the ballast and tried to replicate them with a microcontroller. Unfortunately, I noticed that the SCI signal from the projector has a specific dialogue that I'm not familiar with. I've read much online, but nothing has clarified it. Could you provide me with a hint?

Can we glow the lamp without the control card

Would this be a good projector for a golf simulator? I found a lightly used one for around 250.

I enjoyed your fine work and narration.

There is a client, it has power, but no lights, he tells me maybe some problems on driver.

Do you happen to know how it limits rotation? (typically to 315 degrees). I see what looks like a pin protruding from the top gear. Maybe that engages into the casing and the casing bears against the pin at the limits.

hey frank, i recently had to open up my epson and replace the main power board at the very bottom of the case. in my epson, there were 3 different flat ribbon connectors being used. i was only familiar with the most common one where you slide part of it back to unlock it. the second type i encountered I didn't figure out until I took some up-close pictures of it and noticed it said "Push" on it. Sure enough, when you press on it, it unlocks the mechanism that locks the cable in place. The last ribbon connector in use was for the 3 video connector cables. This one I got really lucky when messing around with it and it unlatched. It is a hinge type that unlocks when flipped up.

Mosfet code sir

Thank you so much Mr.frank.for your wonderful repairing video.realy I'm enjoyed

Nice video🎉

@fixitfrank also wanted to send thanks, I had an amp flashing orange and white and took it apart and tested the 4 components and only a single one of the mosfets was bad. I replaced both anyway and it fired right up. Thank you very much! Now I just need to figure out how to get those clips back on...

Hey Fix it Frank! I’m Allan, a highschool student from Ontario, Canada. I recently got my hands on a Christie DHD800 that has a dead power supply. I was wondering if we could get in contact for some repair advice. I’m pretty good with technology and stuff like this. Thank you, Allan

Hello and greetings from Europe - Greece. I followed your video. On the same model RS-57 and i replaced the crappy ballast with the one you are showing here. It worked. Many thanks. Do you know a compatible ballast for JVC - X3 as well ?
