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, 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... -
What's wrong with my TV: the TCON, the panel, or something else? I'm stuck.
Problem:
Last week, my Sony KD-70X690E 70" stopped displaying a picture. The TV powers on, and the back lights power on. However, the TV doesn't seem to boot up. I say this because the SONY splash-screen logo does not display, nor does any picture display, nor can I invoke a menu by pressing "Menu" on the remote. Other than back-light bleed, the screen is black.
My troubleshooting got me this far:
With the left-hand TCON to bottom-board ribbon cable... -
This thread is about trying to get an Universal Main Board to work with a Sharp TCON and panel.
I have a Sharp LC-46D85UN TV that has had a main board issue. Since this model is from 2009, I am not able to find an exact replacement of the main board. Instead, I decided to see if I can future proof this tv by getting a Universal Main Board (T53U21.2) from China to work with the Sharp TCON (CPWBX4291TPZA) and panel. The universal main board supports a 8 bit dual channel LVDS interface whereas the TCON requires a 10 bit dual channel LVDS input. I have modded the LVDS connector to match... -
Hello everyone,
I've recently been given a Sony 8k Z8H. It's got a white screen with two vertical black bars. At times it's given me the 5 blink Tcon code. Testing voltage on the Tcon I can see some low or missing voltage. I've done a basic visual check of cables and the COF. Not seeing anything obvious. The original Tcon seemed to have good caps until turning it over. On the bottom I found maybe 10 caps with both sides of the caps shorting to ground. I thought ok these caps and likely other components on the Tcon are shorted so let's try a replacement Tcon. I just received the...
