My philips 50 inch flat screen vibrates loudly sometimes

for a 50 inch you don't want to know, check vancebaldwin.com and see if you can find yours

I have the same problem. after pulling the back off. we found that the 3 capaciters above the 2 power relay switches are bad. i am currently looking for a scematic so i can replace the 2 dios that burned up due to the issue along with the capasitors.

Call the Philips tv corp. for ur tv warrenty repair.The tv have power supply board,problems.

It's the optical block (color wheel) and the same thing happenned to our Philips 50" DLP. From what I've read, it's not worth the trouble & $$ to fix. Dig a hole!

looks like you cant as it doesnt have the 15pin vga connection

Unfortunately, i have found in my experience is when this problem occours you need to replace the plasma panel, which can be a costly thing to do and takes a little bit of planned time. Other than that you can try to replace the X-sus printed circuit board or the Y-sus printed circuit board. Those two boards control the screen circuitry, Good Luck.

your tv hates you

Commonly it's going to be a power supply related problem. The two boards that need to be looked at is the Main Power Supply Board or the power supply board for the screen. The one that powers the screen, some manufactures call it a Backlight Inverter Board.
If you have some electronic experience, you can sometimes find a Service Manual for the TV over the internet for less than $20. It will have the all resource material for repairing your TV model. It's just the matter of replacing the bad part on the circuit board.
