JVC TV picture problem

Hello, my TV is having issues with its picture. Initially is was just when it was warming up but now its permanent. Basically the picture is stable - no rolling, but there are horizontal lines across the screen flickering, the lines are about 3 to 4 inches apart and about half an inch wide. This is coupled with a whistling noise, although the sound can still be heard over it. Its a JVC tv, AV32T5EKS. Does anyone have any idea what it might be and how to fix it? Thanks Alex

SOURCE: JVC PD-42DX6BJ plasma 42 inch black horizontal lines over the pic

Here's a link to order the original the JVC upper Y-buffer board and lower Y-buffer board for this model from a major parts distributor if needed:

JVC "PD-42DX6" Replacement Part Upper Y - Buffer Board (LJ41-02760A)

JVC "PD-42DX6" Replacement Part Lower Y - Buffer Board (LJ41-02761A)

Based on the symptoms: It is possible that the Y-buffers are faulty, which may require the replacement of the Y-sus board as well. You may want to get a local technician to diagnose the unit and provide a second opinion.

SOURCE: The TV has horizontal lines across about 5 inches

Horizontal lines are relatively rare problem in LCD TVs.

The likely problematic areas are:

1) The LCD itself (the micro ICs embedded into the LCD panel structure); that doesn't sound likely based on what you say, but it's not completely impossible. The bad news is it's mostly uncurable.

2) The power board A-1511-322-D G5
Power boards may sometimes cause problems with display, although rarely causing horizontal lines.
I wouldn't start looking here either, but it is certainly a problem to consider.

3) Main board 1-876-561-13 R1506072C
Slightly more possible and yet not quite likely. A high operating temperature and bad SMD soldering process may cause some soldering contacts on the main board to behave differently when the board is cold versus when it heats up. It is very common and may have all kinds of different effects on the TV and the screen.
One way to check for that is with a regular dryer..the process is explained in many other solutions at fixya and around the net, so I wouldn't repeat it here...but it takes time and patience.

4) The most likely place to start with is the T-Con / LCD controller
404652ASNC6LV4.1 M139.

I'd first replace that and see if the problem goes away.

5) There's a very minor chance that the LVDS cable that connects the main board with the T-Con does not make good contact initially and changes that as a result of getting hot. It's easy to just touch and move it lightly when the TV is still cold to see if it has an effect on the picture.

Sorry I couldn't just nail it for you, but that's the nature of the repair businss :-)

SOURCE: 42 inch LG Plasma TV - Lost picture

Lg Tv-Plasma from 42inch to 55,the poping sound and specially coming on then go off,or just sound and no image after turning on,the problem in very easy to Fix,some other people don`t want to let you know how is done couse all they want is money after we pay a fortune on it....solution?,is all in the main board,i don`t have a schematic but i`ll try to explain at my best,i had 2 of them,they were doing same thing,are 6 years old...solution: on the main board,(connects remote control to tv,gives the signal to turn on the tv),there is 1-2 capacitors that you will see they are black,but a little squeezed at the middle(if an electrician opens it is very obvious),when turned on,there capacitors makes a loud buzzing noise and get very HOT,that`s why the popping sound and black screen,comes on...and turn`s itself off,those 2 needs to be changed,to a higher Voltage,after this is done,you will see your tv back to Life again.

The capacitors can be of different types but the shape is the same,depends of Lg-Tv-Plasmas,42-55inch.
Good Luck!.

My Olevia LT237 37"HDTV shuts off while watching.


Take the TV to a local repairer, it sounds as though as it is warming up some components on the Power Supply are failing.

A fairly common fault, not too expensive to fix.

Perhaps $80 if it can be repaired, $150 to replace the PSU.

No Picture

I am deeply sorry but you will need to replace the backlight bulbs. These are not available.

Look on Ebay for a 32" JVC with a broken LCD Screen. Buy it and use these bulbs to fix your TV. I am sure there will be a few good ones in the broken TV. It's that or list it on Ebay for $50 and expect to get about 200-300.

LCD Panel repair for this problem is $500 for parts so you are stick with repair yourself or sell.
