Question about Philips Televison & Video
I attempted to repair the power pcb in the center of the tv
but decided to purchase the board for $146.00. Reinstalled the power board and still same problem.
There are two rubber buffers under the PCB. What are those for?

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.

Your board numbers should start with LJ92. They will cross to both Samsung and LG. Oh, your model number goes nowhere, double check it.

The power regulator PCB has some fault it it. It does not outs proper regulated voltages needed to the other PCBs in your TV. Normally Plasma TV power regulator PCBs are very difficult to repair, and PCB as whole should be replaced. If you give this set to Philips Authorised service center, they also will do this, and they too can do only this. In my opinion, it is best to get it repaired by Philips Service center, because, Plasma displays are very sensitive to static voltages, and repairing it without proper measuring instruments and circumstances, may damge it and it is irreparable. If fuse is gone out, you must aware that there must be som sort of short, or overload inside your TV circuits. If you have technical skill, a proper knoledge of the power regualtor working, and mor confidence and patience, you can do this. You have the ability to follow the schematic diagram of your set, which can be obtained from philips website. You must have a high quality digital multimeter, and static free DC soldering iron to go on. Some times, an Oscilloscope may also be needed.
Beware, your TV has built on most modern electronic technology, and is colstly one. Never attempt anymore on it, if you are fully aware of its working principles, and proper knoledge in Electronics. Philips uses some special components of their own, which cannot be purchased locally.
Determine yourself, what to do. OK.

SOURCE: We have a 50" Magnavox
My guess, as there is very limited information on your TV, is that you are in need of a new bulb. The problem is that it could be the bulb or the ballast that connects the bulb to the TV.
