Question about Philips 60PP9202 60" Rear Projection HDTV-Ready Television
1.) This sounds like a convergence problem--with the original remote go into the customer menu and select convergence--see if red or blue will not move in some direction.
2.) If some color (red or blue) will not move in some direction--you need to replace both of the STK-392-120 CONVERGENCE IC'S THAT THIS SET USES along with any of the green 6.8 ohm resistors around them that are discolored(bad).
3.) With the back cover removed the chips are on the left large board on two metal heat sinks with fins--they are black and about 2 1/2 inches wide and 1 1/2 inches tall and the STK-392-120 is printed on the face of them in white. The resistors are in front of the one near to the front of the circuit board and left to right around several plugs there(convergence yokes).
4.) You can buy both chips on Ebay for about 13 dollars plus shipping; If you are able to do this repair you can save a lot of money---after the chips and or resistors are replaced you need to go into the Convergence Tech mode(I can tell you how to access it) and adjust the convergence in first the regular non Hd and then in the Hd.
5.) Most shops TRY to charge 300-400 for this kind of repair--I have done hundreds of them here for 200-250.
6.) If you are not able to do this repair shop around your area for someone who can do it---if a shop says "It has to go to the shop" keep looking----any good tech can do this repair in your home in about 1 hour.
7.) If you have any questions or need advice reply to this posting.
