Question about Philips 50PF9731D/37 50 in. Plasma Television
MISSING RIGHT SIDE OF PICTURE
Back - light problem. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis.
In some models of LCD TVS; the backlight inverter and its T'Con board will be a part of the panel itself, and will be a built-in type inside the LCD panel. If so, they can't be replaced. In this case; a panel replacement is the only repair. For some other models, the backlight inverter section circuit will be a part of the main power supply regulator [SMPS]. To such sets, the power supply section circuit too should trouble shoot. Contact any service technician. The circuit will differ with models and versions.

This is an LCD television, you may find at the top of the LCD display a module referred to as a t-con module (timing control module).
There are usually two ribbon cables that make connection from the T-con to the display itself. Check these cables for corrosion or burn marks that might be preventing video passing from t-con the the display.

If the set is no longer under warranty, open up the back and reseat all of the connectors and cables. You are seeing a heat related connection problem. If it is still in warranty, bring it in for warranty repair. The other possibility is a heat related connection at the processing chip(s). This is a more complicated repair that should only be done by an experienced tech that works with surface mounted components.
Keep us posted.

Take the back off the unit. There are 2 20 pin cables that go to a small board that sits on the right side (viewed from the rear) spray the back of the plugs with contact cleaner and wiggle these cables where they plug into the small board.

You should have downloaded the eprom information onto a usb stick then transfered it back to the new board, or just removed the eprom off the old board onto the new. It is my recommendation to have an authorized service center come out and realign it within the factory service mode.

Have the Digital board and logic board replaced. the most common problem will be the logic board assembly. Altho the Digital board can also cause this problem. Try taking off the back and making sure the LVDS Cable is connected tightly to the logic board assembly and the panel, (Scrn), The LVDS Cable will look like a small wire harness with two metal clips on each end make sure it is secure, try disconnecting it and reconnecting it again.
