My philips 60" philips tv model 60pp9352 picture is squeezed at the middle (like an hour glass on its side), how can I fix?


This is a very common failure on Projection TV sets.
Screen looks 3D
Colors don't line up
One or more colors can't be adjusted when using the convergence menu.
Screen is bowed or warped.
You can see some example photos and find a solution here...

Hourglass Shape


If there is a hour glass shape to the image but convergence is normal, there are 2 possibilities. You either have a pincushion correction problem or if the hour glass seems to be moving, it will be an open filter capacitor in the power supply.

Unless you are electronically inclined troubleshooting this issue will require a factory trained service technician. You can expect to spend $300-$400 to fix this.

You have a problem with the STK convergence modules. They're on the center circuit board attached to an aluminum heat sink that's about 8" long and 6" tall. You may be able to recreate the problem (hour glass effect) by gently moving the heat sink (which the modules are connected to). This gives the hour glass effect on the picture and the advanced convergence screen. This is an indication that the modules pins aren't solidly connected (meaning soldered) properly. Remove the circuit board and clean the old solder off & resolder the modules pins to the circuit board reconnected the board and then retest by again pushing on the heat sink. The "factory" job was good enough for 3-4 years but the heat (and these modules do create a lot of heat) and stress created from repeated use eventually takes it's toll, weakens the pin connections and our problem occurs. take the appropriate cautions working around the high voltage of the set & use a non-conducting piece of wood to push the heat sink when doing tests.
If soldering doesn't help, then the modules have died and need replacing. Don't buy the $10 cheap ones. Most of them have an upgraded version that is stronger. Also look for any burned resistors in the vicinity of the modules.
Best of luck, hope ya fix it.

Was the hour glass upright or sideways? From what you described I would say you have a pin-cushion problem. Let me know if you need any additional info.
