Have you ever stopped to think and then forget to start thinking again?

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... -
Hello
I have a big problem and that is that in some cases when repairing active pfc power supplies I cannot work with a test lamp. I can only get help with 5 volts standby and for starting and starting I have to work without a lamp and this way there is a possibility of parts exploding and other parts being added.
Sometimes with a multimeter test the problems can be reduced to some extent, but I had several cases that had to be tested on and online and recently two varistors exploded. They had terrible resistance because the power supplies were over 800 watts.
Is there a way... -
Hi all,
I have this Sharp LC-60LE810UN that stays off and blinks a Lamp Error (1 long flash followed by a short flash, in a loop).
I already confirmed that the first backlight strip has an open LED using a LED strip tester. The other 3 LED strips are fine.
Before tearing the LCD panel apart, I want to make sure that the rest of the TV set is good. I've tested the power-supply/LED inverter board by sending 5 volt to PS-ON, to PNL-POW (that commands power the T-CON board only), OFL and STB pins. The power-supply is good.
I've tried all the key...
