I was given a 50" Panasonic DLP TV. Some sort of projection TV using a lamp. Owner said "screen turns green sometimes". I have fired it up and it has a nice picture. I have no experience with this type of device and was looking for any comments or direction to get me started, before I tear into it, should it fail. Does anyone have experience with such a critter?

Re: Panasonic PT-50DL54J
OMG. Been trying to find something to read on this DLP thing, and it is getting pretty deep. Evidently have one or more DMD chips and maybe a color wheel all of which is new to me. Sounds like smoke and mirrors. I don't know anything, but it seems certain, the lamp is not causing the problem. I have not seen the picture go green yet, so I will leave this set running, and try viewing B&W as well to see if I can provide more useful information. If anyone has input, I would like to hear it. If it does act up, I guess I will have to open it up and see what is in there.

Hello! yes I know there is already lots of information about this issue. I have a Panasonic TC-P55ST50 that originally displayed an 8-blink error code. Following the troubleshooting flowchart, I ended up replacing the SS board. However, even after replacing it, the issue persists. The TV turns on and stays on without displaying an image, and continuity is confirmed on all connectors. What am I missing here🤔?
Ok Im a mechanical engineer ...but I thought I was able to follow a rather simple flowchart for electric troubleshooting 😂.
TV Model: Panasonic TC-P55ST50

Hello. I am asking you for a hint on how to solve the problem with my touchbook Panasonic CF53-2 standart model. After setting up the BIOS, the laptop displays the wrong image until Windows loads. (More precisely, it displays, but distorted, instead of the Panasonic image immediately after turning it on, it displays what is in photo #1 in the attached file) Then the image appears when Windows starts loading and then there are no problems with the screen until the reboot. If you enter the BIOS, just a black screen. If you connect an external screen, the image on it is the same as on the built-in... -
Hoping someone here can put me on the right track. I'm trying to troubleshoot/flowchart the "internal projector error" on my newly acquired Facebook Marketplace bought Epson 5040UB projector (3LED, not DLP). Owner said it needed new lamp, actually error code blink pattern indicates "Internal Projector Error, call Epson support". Unit is out of warranty as of 8/19
Here's what happens:
1) Power on
2) Blue power indicator lights and the lens cover motor opens the lens cover, light fan noise heard
3) Blue status light flashes for appx 4 minutes... -
Hi All.
Does anyone have any reference materials or something I can use to try troubleshooting a BenQ TH681? Google unfortunately has turned up zip. I did find a service manual for a W series BenQ but that is pretty much useless, it's more a glorified user manual. A list of voltages would be great as I suspect my mainboard is faulty, the colour wheel voltage is not dipping like it should.
The one I am troubleshooting now was originally overheating after a lamp replacement. It originally would take 2 minutes or so for it to shut off and blink the temp and lamp lights... -
Hi,
This monitor previously is my main working monitor which i have been using for 8~9 years. Yesterday, when i switched on my pc from fresh to power on, the monitor is just black no display. I started dismantle to look inside the monitor power board but nothing looks suspicious or burnt. So i took my external ccfl inverter to try to power the monitor ccfl lamps which consisted of 2 lamps on upper part and 2 lamps on the lower part.
Found out the upper ccfl lamp which is supposed to connect to cn304 on the power board did not light up. Then i installed a used working...
