Vertical colour bars


The problem is in the LCD controller board is overheated because the power supply unit is at the bottomof the TV and the heat rises upward to the vent on the top of the TV. You can verify that is hest problrm by running TV with the back removed and have a small fan blowing on the top secdtion of the TV where the LCD controller is. This how I fixed my scrambled picture after warm up (I added heat sinks to the IC on the LCD controller board) : http://s807.photobucket.com/albums/yy352/budm/LTV-32W3HD/
You can try it if the board was not badly damaged already by the heat. My has been running great for over a month now.

Vertical color lines


I had the same thing happen to me this morning. I turned on the TV and it had colored vertical lines through the whole screen. I called Sony and they had me unplug the TV for about 15 minutes. This solved the problem. They said the boards just needed to be reset. It fixed the problem and I am happy with my Sony once again.

We have many problems with loose or poorly seated cables and connectors on these units. Pull the back and reseat all the internal cables, especially the LVDS cable to the LCD control bd. If this does not correct the problem the main cause is a bad LCD control bd. or possible a defective main bd.

Poor Picture Quality on Philips 42PFL7962D


Get the professional, although this won't be an expensive fix... You likely have one or more caps in the vertical circuit that are going bad... A cap acts like a battery in a circuit taking on voltage and releasing it at an even rate. When they go bad their ESR (equivilent series resistance) rises and the cap takes longer to reach it's op temp and work properly...
A tech with an ESR meter will easily find and repair this one...
no other issues only a minor problem..
