TOSHIBA TV SMART: Toshiba screen black with sound (was flickerering previously)

Thu, 16 Oct 2025 09:12:55 -0700

Hi all, wondering if somebody could advise me if my tv is worth fixing?

Toshiba tv (Model - 50UL2063DB) started flickering in the bottom sections of the screen for a few weeks and then 1 day go to turn it on but the screen switches on but stays black (well a lighter black then when it's switched off). - screen then switches itself off after a minute or so.

I can hear sound in the background.

What I've tried so far, unplugging any devices and trying to get the tv menu up on the remote (Nothing).

Shining a flash light at the screen but see nothing.

Unplugging for a couple of minutes but still nothing.

Took the back panel off disconnected all the wires to the tcon board and other boards and reseated them, still nothing and no visual signs of damage (that I can see but I'm not clued up on tv repair).

I've read it can be either the tcon board or the main board that needs replacing, is it worth trying to replace these, if so which one is it likely to be?

Thanks in advance.

UPDATE - I removed one of the 2 ribbons on the tcon board and half the screen lights up as usual now and picture is back to 1 side but then does start going faint - does this confirm a tcon board problem? - please help

TOSHIBA TV SMART: Picture still distorted and white

Thu, 16 Oct 2025 09:15:14 -0700

Need Help!!!. I've been trying to repair a Toshiba 50ul2063db. The TV was only 15 months old when it went faulty. The picture would not come through but still had a glow which told me the backlight was ok. After watching loads of YouTube videos I decided to replace the mother board but still had same problem. I then decided to replace the Tcon board, a picture did come through but it was white, distorted with horizontal lines and also the whole picture would flick from white to black every other second. I then decided to remove a ribbon cable from the Tcon board. The first cable was the left, the picture was dark on one side and white on the other but I could make out the app images when I pressed the home button on the remote. I then put that cable back in and removed the right cable from the Tcon board. The picture was distorted both sides.

. I have also cleaned the ribbon cables. The parts I changed were not brand new. Any help please

Still struggling to identify which panel is at fault left or right. I have tested the standard voltages on the Tcon board and they are all what they should be. Also I've checked the ribbon cables and there not in the best of condition see pics

If I take the right ribbon cable out of the Tcon board the right panel goes black and the left panel goes white but can see a slight image from pressing the home button on the remote.

If I take the left ribbon cable out with the right in, the left panel goes black but the right panel has a backlight glow with some horizontal lines

Which panel is at fault

TOSHIBA TV SMART: Picture almost has a wavy pattern

I bought a Toshiba TV a while back and recently the picture looks like it's pulsing/wavy. Almost like the refresh rate isn't right or something. I can't really tell what's wrong with it. Anyone got any ideas?

I have a Toshiba smart tv 50 inch and I have started experiencing a flickering screen, I have tried replacing the T-CON BOARD but it doesn't make any difference. I've tried blocking part of the t-con connectors which improve the screen slightly
