Hey looking to pict this tv up possibly but I don't know where the issue might be. Person says the tv turns on and has a picture but it's dark and after it warms up its picture is fine and has no problems. Would this be in the back light maybe a ccfl bulb going bad. Or lcd display going out. She said if you turn it off after it's working fine and turn right back on it is dark again until it warms up. Maybe capacitor going bad. Let me know what you think

Re: Kdl-40vl160 dark picture until warmed up
99% sure it's tab bonds...
I'd avoid it. The 40" Samsung panels used in these Sonys don't have a good track record for repair reliability.
Some last but the vast majority can't be fixed for any longer than a few days.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Was watching this set, and suddenly it went dark. Picture is still visible, just very dark. Tried checking all settings, adjusting brightness to 100% no change. Reset through menus, no change.
bought used boards from ebay (power and input boards) replaced with same results, changing brightness does seem to have a slight affect.. but not to normal visibility of picture.
I'm handy, fixed TVs before.. I can't see any issues with boards... hoping someone can point me in the right direction to properly diagnose. I don't believe the LEDs are caput, since the picture is on and equal... -
Hi all
While I have quite a decent background in electrical & electronic troubleshooting & repairs, this is my first time stripping down an LCD TV for repair.... I have inherited a 3yr old Panasonic LCD which has a picture, but it is quite dark (too dark to be watchable - but still quite easy to see; I didnt need a torch to see it).
I started by checking and trying to adjust all of the picture and backlighting levels, but that made little to no difference. I also did a factory reset.
From there I envisaged that the backlighting wasn't working, however... -
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)... -
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...
