Re: Sony KDL-40EX503 bad panel?
That's a crap shoot. The complete green band looks almost like a tcon problem. Also the band looks to be extremely wide to be one tape carrier bond out. Looks like two bonds are not active. The chance of two out at the same area are rare. I'm going to say tcon. Lets see what others say.
Edit: I looked closely at the picture and it looks like the ribbon on the far right is only producing half the image. So that makes me more likely to say tcon. Slight chance it could be a faulty connection on the ribbons going to the panel. You could try reseating them.Last edited by freakaftr8; 01-19-2015, 10:44 AM.Did I leave the soldering iron on? -

Hello.
I was so lucky finding another T-con of the same model. And it appeared the T-con was at fault. Thanx!Comment

Hi,
i want to repair a Sony KD-75XF9005 TV that initially only showed a grey picture.
Backlight seems to work, Sound (Setup menu after reset) works.
If i dissconnect the left FFC cable from TCON to panel i have half a screen on the right. If left cable is connected always only the grey screen.
Interchanged the cables, its always only the right side that is working. Always grey if left side is connected.
With my small knowledge i would think at least the cables are good.
Can this happen because of a bad tcon board?
Or is it always a bad/shorted... -
Hello all ~
Hope this finds you well. This LG 82UN8570AUD (April 2021 model) 4K UHD television has full audio capabilities but video is compromised / problematic.
When I picked up this large LG tv it had a full black screen upon startup. Previous owner said it just went black one day. No popping sound or anything else of note.
I got the display to work by taping off several traces of the right-hand side ribbon cable on the TCON that leads from TCON to PANEL. However, despite dozens and dozens of attempts to find the right combination / range of traces taped... -
Hi, hoping for some views on this one which I've not come across before. The TV generates an image that has 12 noticeable bands across it. The image is still there and accurate, but the colour (or perhaps the brightness) changes gradually across each band which creates a noticeable 'step change' at the edge of each band. Given it's a 4K TV with 2160 rows of pixels, I'm guessing the 12 bands correspond to 12 gate drivers of 180 rows each. If this guess is right, then perhaps:
a) all the gate drivers are malfunctioning the same way (which seems unlikely), or
b) the Tcon board is malfunctioning,... -
Just bought this for 10 bucks yesterday hoping to fix it. The guy said water dropped inside from a dehumidifier hose and it started showing black and white vertical bars then went blank. When I got it home and turned it on it came on fine and displayed correctly but I was noticing faint vertical bars in the image. After a little bit I turned it off and back on and it was a black screen again. I opened it up to check for water damage and corrosion but didn't find anything of the sort. I cleaned the ribbons anyway and reconnected them but still got a blank screen. If I disconnect the right side... -
Good day, I have a TCL TV: Model 43s423. After turning ON the TV, the ROKU TV logo appears with fine lines over the whole screen, then after a while there are vertical bands in the middle of the screen top to bottom and the TV tries to update its firmware but I do not have the remote to connect it to my new network connection. Also the Power ON light blinks 2 times in quick succession. When I remove the ribbon on the right of the tcon board the left side of the screen shows but with fine lines. If I remove the left side ribbon and connect the right side ribbon the whole screen is blank with...
