Question about Akai PDP-4247 Television

Black vertical line

I have a 2" vertical black line running down the left side of my screen. It started out as a thin greenish line then eventually turned all black. It is out of warranty so Sony wants over $1000 to replace it. Any suggestions? It is a Sony 42" flat panel display Model FWD-42PV1/B.

The drive module for the screen, or the screen itself has to be replaced. Either being defective can cause your described fault condition. The service tech would find the defective board by swapping them with new ones.

These parts are expensive.

There is no supported component level service on the circuit boards. They use complex SMD technology, and it would be impossible to troubleshoot these boards as like was done in the older days in equipment that used standard type components.

One way to fix your set, is to find another defective set of the exact same model, and swap out the required parts from it. The problem here is that there is a good chance that the same parts are defective in the other set. In this case, you would still be left with the same problem and have spent good money to buy another defective set.

If it was possible to have your TV set built with standard type discrete components, the electronics would be many thousands of times their size, and the cost would be unaffordable.

There is a vertical black bar along the left side of my TV. It started as a thin yellow/white bar and has grown to be about 2 or 3 inches wide, blocking that portion of the screen.


The LCD wafer has gone bad, and more lines will begin to appear over time. It can be replaced but the cost may be comparable to replacing the entire television.

IF YOU HAVE A SOLID BLACK LINE RUNNING VERTICALLY THEN YOU HAVE A FAULTY MATRIX INVERTER. IF CENTRAL THE MAIN VERTICAL INVERTER NEEDS CHANGED. LEFT = LEFT VERTICAL INVERTER RIGHT=RIGHT.........

ANOTHER WAY TO GET THIS FAULT IS WORN OR DAMAGED RIBBON/PLASTIC GOING FROM THE SCREEN MATRIX TO THE INVERTER

Hi,
The black vertical line is caused by a leaking capacitor, Check and replace poped capacitor with a new won and it will work fine again. No worries.
