Re: Sharp LC40LE240EX
Just an update, as the led is flashing coming out of standby the screen gives one quick white flash and then nothing more, even when I shine a torch on the screen you still can't see any picture at all -

I have a 60 inch Samsung UN60EH6000F flatscreen TV. The screen went black a few months ago Sound is good, backlight is good, no menu. I replaced the TCon board with a used board purchased from Ebay. It worked fine for a 3-4 months, then the screen started βfading' back. Once again, sound is good, backlight is good, no menu. However, this time the picture looks fine for about 10-15 minutes, then fades back. If I power cycle the TV, the display reappears, for another 10-15 minutes, then fades black again. Repeatable ever time.
I ordered a supposedly βnew' Tcon board this time, and... -
Hello everybody! Posting this in hopes somebody has some expertise that leads to a clear path of troubleshooting that saves me a lot of time!
My macbook has the flex cable problem, the one that prevents the screen turning on. Ive been dealing with this for the last 3 years. Last year it went dead and I managed to fix it following youtube tutorials. But my fix wasnt the best, the problem returned a month later. This week, it went dead again. I again tried to fix it.
This time the original cable broke too close to the screen, it can't be fixed without tearing the screen... -
Another TV topic!!
I got this sharp TV that when I first plugged it in it showed the sharp logo and then went to the input screen. This was about 30 seconds and then it showed white screen. Now I can't see anything but white screen. This has a separate TCON and Main.
The TCON is getting 12V and several parts are as well but the VGH line is only .5Volts which I thought is totally incorrect.
Am I on the correct assumption that the TCON is bad somehow if I'm only getting that voltage or is there something else I should check?... -
Have a Samsung UN50NU7400 which shows a boot screen and a screen saver if left on long enough but no picture ?
Would a moving screen saver confirm that the panel is ok or it could still be a panel issue ? -
Hello, I need your help for a failure on a laptop:
It's a Packard Bell Kayf0, motherboard LA-5021P, Rev 1.0 with graphic issue.
I received this pc because it was turning on but not displaying anything, the fans are running normally and all chipsets heat up on startup but no picture on screen, no backlight either. I noticed that ENAVDD and ENVDD are not present and that there is no LCDVDD on the connector. I didn't check the screen because, maybe I'm wrong, but if there aren't these signals, even if the screen is good, it can't display anything? I tried heating the...
