Re: Pansonic TH-42PX25 double half picture
Uh... wow. Odd one.
That's one of Panasonic's first plasma sets; 2002 era. It is HD capable, 720p resolution. Still has a good picture for an old set, with fault ofc, but not bad for modern consumer electronics.
As for the fault, does that split between the two halves wobble, or is it fixed as it is?Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!
For service manual, schematic, boardview (board view), datasheet, cad - use our search. -

Re: Pansonic TH-42PX25 double half picture
Did more testing/research on this set,,,,when you go to set-up screen,,,the screen is totally normal,,,now select computer monitor mode, it works perfect....Which ever board controls some of the input other than vga has a problem....
This is going to be used as a computer monitor / shop display,,,so really don't need to put more time in it other than to assemble the back!!!!Comment

Hi,
I have a VIZIO E70-E3.
Symptoms: Black screen, no picture, but LED backlights are working.
I probed the power board and voltages are as listed on the board.
Main board appears fine, too.
I believe the problem is either a bad T-CON board, or connection to LCD, or bad LCD.
There are two separate ribbon cables feeding the LCD.
If both are connected, the screen is black.
If only the ribbon cable that feeds the right side of the screen (when viewed from the front) is disconnected, the left side of the screen shows picture and... -

This was my main TV for the last 6 years. I'm not inclined to throw out a $2600 TV so quickly so I'm trying to investigate the issue.
Problem
TV was disconnected from power for 6 months during construction. When I plugged it yesterday picture was fine, after 30 seconds it dimmed then started developing horizontal lines, picture then starts to ghost vertically until it degrades into vertical streaks. TV always displays a perfect picture when cold. I can unplug TV for 5 minutes and plug it back in and picture is restored for 20 seconds. I can also keep it in standby mode... -
Hi, I have a Samsung UE50TU with:
- sound and backlight, but no picture
- when it arrived, it had a picture for a few seconds
- it keeps rebooting
- without ribbon cable between the two panel boards, it does not reboot but I have no picture
- without cable between mainboard and lcd panel, it does not reboot (but obviously i have no picture)
- when i try a tape fix, its keeps rebooting, unless I tape off pin 1 (the innermost pin). In that case it does not reboot but I have no picture.
- without cable between mainboard and lcd panel and with a jumpered... -
Anybody have any ideas why half the picture would be slow to refresh?
