Good job! I've got two here now that I wish I could solve.-
Hi guys! I realized you have a lot of knowledge here so i am hoping you could point me in right direction with my odd issue.
The Tv is a Philips 58PUS8545/12, it had no picture but working backlights.
Original T-con:
Opened the Tv and tested to unplug one ribbon cable at a time. With this test i could see that i got fine picture on both halves as long as there was only one ribbon cable connected, with two connected picture were gone.
First replacement T-con:
I thought it might be t-con and ordered new t-con from china(supposedly tested)... -
Hoping someone has troden this path before !
I'm looking at a JVC LT-39c790 - a vestel based unit.
So, the remote turns it on, led's light up but no picture at all.
I have a spare mainboard, so I know its not that. The PSU seems ok too.
On the AUO T-Con I've got 16v on HAVDD_H but nothing on HAVDD_L - which I'm assuming should also be 16v ?
So, Ive resorted to testing eveything I can on the board as I can't find any schemas for it (AUO 39T15 C04 Ctrl Bd) and I think I've found a diode gone short. it marked D005 on the board and E1 on the package... -
This was my main TV for the last 6 years. I'm not inclined to throw out a $2600 TV so quickly so I'm trying to investigate the issue.
Problem
TV was disconnected from power for 6 months during construction. When I plugged it yesterday picture was fine, after 30 seconds it dimmed then started developing horizontal lines, picture then starts to ghost vertically until it degrades into vertical streaks. TV always displays a perfect picture when cold. I can unplug TV for 5 minutes and plug it back in and picture is restored for 20 seconds. I can also keep it in standby mode... -

Hi, I have a Samsung UE50TU with:
- sound and backlight, but no picture
- when it arrived, it had a picture for a few seconds
- it keeps rebooting
- without ribbon cable between the two panel boards, it does not reboot but I have no picture
- without cable between mainboard and lcd panel, it does not reboot (but obviously i have no picture)
- when i try a tape fix, its keeps rebooting, unless I tape off pin 1 (the innermost pin). In that case it does not reboot but I have no picture.
- without cable between mainboard and lcd panel and with a jumpered...
