    Have checked all cables and changed the control pcb , still the same , service manual is very poor a explaining the PDP part of the tv . suspect the the fault is to do with the plasma control itself, but not sure which panel controls that . or is there some adjustment required as I have replaced some of the pcb's .Any body know which panel controls the plasma ?

First check all of your ribbon cables. then check the lvds cable. if this dont fix then you will have to get a service manual and run the panel by itself to determin wich circuit your problem is in. any questions feel fre to contact me....

    sorry but there arent any adjustmensts that will fix this. th issue you are experiening is a signal issue. this issue could be in the logic main board, th y susain board, or the lower y sustain buffer board. th only way to know for sure which one is to use an oscilliscope.

LG Plasma has sound but no picture


Hi James,
This could be one of two problems. I can't narrow it down any further without having the set in front of me.
1. The plasma panel or the componets which supply electricity to the plasma in the panel have packed up.
2. The video processing unit in the set has gone.
As for the cost of repair, if it's the panel, buy a new TV. It'll be cheaper. If it's the component that supplies the electricity to the plasma on the panel or the video processing unit, expect to pay between 300-400 as a conservative estimate for parts. Labour would be another 100-200.

Hope this helps

Issue with LG Plasma tv model # DU-42PX12X


Another "same probelm"

My set has encountered this magical 50/50 split screen and it seems to be quite a problem since I am not the only one researching this issue. LG was of no use because of course it is just out of warranty. Any solutions on fixing this or am I out of money in buying a new plasma?

Plasma tv has sound but no picture


Check all the cable connections at the back, if you are using an external receiver , then check the Video cable, eventually try a replacement one.

Try leaving the TV set unplugged for a couple of hours, this will drain power completely and, if there is no real fault , this can fix the problem.

If that does not fix it, then thereis an internal fault.

Common faults that cause audio but no picture concern, digital board, controller board, sustain boards, Plasma screen ribbon cables, and plasma display.

Call the number listed on the owner manual to get assistance.

If the warraty is expired no longer than three years, ask the price fod r a warranty extension calling same number in the manual.

Multi coloured vertical stripes on plasma screen


With half of the screen working, and with a Plasma tv. I will look at the driver board as being bad. Take the back cover off, the driver pcb will be at the top or bottom of the set. They are only about 2 inches tall and will cover most of the lenth of the set (2 boards that run end to end). The board that is on the side of the tv that is bad is the bad board. Replace that board or have a tech replace it.

NORCENT PT -4233


Norcent PT4233 no picture, black screen, but has sound. How to repair

The display (PDP - Plasma Display Panel) at the heart of this unit is a LG 42V7 model. There is a known bad solder "defect" on the YSUS board that causes this board to fall unexpectedly.

The bad news is that you have to replace all the primary boards on the display - ZSUS, YSUS and CTRL boards, as the failure can/often takes them all out.

The good news is that LG makes a repair kit for this panel. Its part number is 687VSNB03E and it contains the three boards LG6871QYH036D (Y SUSTAIN), LG6871QZH041B (Z SUSTAIN) and LG6871QCH053G (CTRL).

Hope this helps

Lost half of picture


This can be on the matrix drive board, or the display assembly itself. It is possible to also have a defect in the address decoding area that will cause this.

The procedure is to swap out the suspect boards to determine where the fault is, leave the working boards in the set, and then follow up any necessary calibrations that are necessary.
