Hi All,
Please see attached photo - does it look like a panel fault or TCON issue.

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... -
Hi everyone!
I have a Sony KD-65A1 TV with a fault – 4 red LED blinks. After disassembly and visual inspection, I found that the G76 power board and DKA board had been replaced. It is also possible that TCON was replaced, but I am not sure – there are a few marker marks that could be factory-made.
Based on assumptions, the previous service attempted to solve the issue by replacing potentially faulty components. I decided to investigate further, found a service manual, and figured out a way to power up the power supply unit autonomously and put the OLED panel and... -
My goal here is to be able to use boards on hand to swap into faulty sets when the faulty board is not obvious.
I will start by asking what is the format of the output from the mainboard and is it generic in any way or does it vary by manufacturer and/or model ?
And as far as I know a tcon and panel must be a matching pair because the timing of the signals and the voltages required to drive the panel are specific to the panel itself. (That may be a blanket statement that isn't true in some cases where the panel creates its own sub-voltages on its panel boards?)...01-06-2024, 01:32 PM -
TV came on with BL on but blank screen. Disconnected one of the ribbon cables from tcon to panel driver board and now I have half of the screen working normally. Any way to tell if the problem is with the tcon or the panel driver board or the panel itself? Should I just replace the tcon and see what happens? -
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,...
