Question about Toshiba 42HP66 42 in. LCD Television

1 Answer

I have a toshiba regza 52" lcd tv. After about 20min the left half of the screen develops lines from top to bottom and then freezes and turns red or green or blue or multi-colored but there is no visible picture on exactly 1/2 of the screen. After it is shut off and turned back on it works for a bit and screws up again.

Three possibilities: LCD panel TFT driver circuits, T-CON board, main board LVDS driver IC. I would get a can of cold spray fro electronics troubleshooting and start cooling the ICs in the main board, T-CON board (you need to remove metal shield to get to the T-CON board to see if it is heat related problems.
If you are going to DIY and have proper tools, electronics knowledge, and know safety precaution then please read on:

Our Toshiba Regza LCD TV has developed a thin white vertical line down one side and a green horizontal line across the middle. The bottom half of the TV screen then comes and goes in muted and faded...


Hello,

All Plasma and LCD TV have boards that control vertical and horizontal output to their respective areas. They are connected to the screen by ribbon cables. If one of these boards fails all together, has a failed chip, a bad connection, or a bad ground somewhere it will result in a black line in the area of that board. A bad ribbon cable connection on the bottom will result in a vertical black bar though the screen. Many times resetting the connection will fix it, if the ribbon cable has been nicked there could be a severed connection. They an sometimes be fixed, but it is a pain. An yes I have done it, but the bar is gone. The same will happen if the chip that outputs to that area opens. The connectors are the first place to look paying close attention to the cable, they are extremely delicate so great care must be taken . Good luck in solving the problem....

My 52" Toshiba Regza has a six inch vertical line just left of center that changes color as the picture changes. Some times it stays with the same pattern for quite a while. It goes away when I turn it off...


you must either change the t- con board, or the left board strip. it is dangerous because mines caught on fire. but most like since that strip is connected to the lcd screen u will have to replace the whole entire screen.

Toshiba regza 52xf550u has a 6 inch multi colored line in the middle of the screen...what is the problem


If it flickers and changes colors like my 52" did, I removed the back panel cover, tore off the cheap foil on top and removed the t-con board. Used a head gun as I seem to fix alot of things with it now adays since lead free solder is cheap, heat the points up for about 2 minutes, replace it and throw some air circulation. I also noticed the top of my lcd has two main boards the are supposed to match up a platic pin and slide into place, the boards were warped and wouldn't stay down. I used a dremel polishing wheel, cut it in half and wedged them down and tv is running clean again.

This will most likely be down to your screen controller board, Take the back of the tv and look towards the top middle, You will see your screen cable go into a rectangular board this is sometimes covered by a metal plate, remove this and check Ebay or Google for a replacement, there will be a part number on the board
Hope this helps?

Vertical red line on Toshiba REGZA 52HL167 tv.


I have this same problem with my 52 inch toshiba regza , The repair shop has said the cost of repair is as much as it is to replace the TV. I am past the one year warranty, but less than 2 year ownership, so Toshiba won't fix the known issue. Solution is don't buy a Toshiba

Multi colored lines running from top of screen to bottom


panel is cracked the cost of the repair is usually about 90 percent of the cost of the tv when purchased new. panel and labor. not worth if panel is cracked.
