20 Most Recent Philips 50PP9202 50" Rear Projection Television Questions & Answers


Replace both of the stk convergence chips this set uses--as seen from rear on far left board on black heat sinks that are side by side and should be stk-392-120 with that number on front of them.There are kits for this on the internet which contain all or most of the needed parts. (TV repair parts . com is one)

If its chirping its likely a short in the convergence circuit. Goto www.TvRepairKits.com and see if they have the part to fix it

Projection TV2_bing.gif sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the video to look normal. When its out of alignment the video will look 3D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the TV menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired.

Convergence problems are very common on all Projection TV sets including Sony, Samsung2_bing.gif, JVC, Philip Magnavox, Panasonic, Akai, Pioneer, Hitachi, Zenith2_bing.gif, and others. You can get a convergenece repair kit from the link below.

Common Symptoms include....
  • Screen looks 3D2_bing.gif
  • Colors don't line up
  • One or more colors can't be adjusted when using the convergence menu.
  • Screen is bowed or warped.
  • TV shuts off after powering on - TV may also make a chirping noise.
Here are some photos of convergence problems.

Here is a quick test....

Using your original remote go-to the settings menu then goto the convergence section.

Try to adjust the red and then the blue convergence.

You should be able to move RED and BLUE in all directions - up, down, left, and right.

If you can't move them in all directions or cant move them far enough your convergence chips are bad and should be replaced. This is a common problem.

Note: If you TV has as flash2_bing.gif focus or magic focus button only try pressing the button. If it fails to fix the convergence your need to fix it. See below for a solution

You will need to replace the convergence chips and possibly some convergence resistors and pico fuses.
This is a a fairly easy DIY job if you know what you are doing. If you have never done this before we would advise calling a shop or if you want to do it yourself get a complete kit with instructions and support from www.TvRepairKits.com

How old is this TV?
I think TV requires Screen Volts Adjustment and qualified TV tech should perform that adjustment.
Thanks.

Mine's doing it too. Bad convergence amp IC's. STK392-020

Philips 50PP9202... • Answered on Jul 27, 2009


Your original problem was/is an "opto" IC (chip),which causes the power supply to regulate low when it fails. It is a 6 or 8 pin chip. Sounds as if maybe more has failed now. Switch mode power supplies are not for the faint of heart,or DIY. I recommend having it troubleshot by a tech.

just about 16 oz. One 16oz bottle is enough for each picture tube (Gun)

You have one of two problems. Sometimes both.

Problem #1) CRT Fluid is Cloudy

Projection TV tubes have a liquid coolant that is used to keep them from overheating. After many years the coolant in the blue and green tubes will become cloudy and cause the screen to look dull, red/orange, etc. You may even see halos around images.

Picture of a set that needs the fluid changed.

What you will need to do is replace the coolant and clean the crt. You can get a repair kit from www.TvRepairKits.com that includes replacement coolant, photos. instructions, etc.

Problem #2)

Your TV may have a convergence failure. ( common problem )

Here are some of the most common symptoms and example photos of a convergence problem



  • 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.

Your convergence ic's went bad and possibly took out the fuses in that circuit. I believe they are stk392-120's on that set. Also, check all the resistors around them. Should be located on two heatsinks near front of chassis. Good luck.

Philips 50PP9202... • Answered on May 19, 2009


All convergence circuits require two voltages which are equal, one being positive the other negative. Check the power supply for these two voltages and then see if you're getting them at the output ICs. I suspect one of them is missing or low. If there are no cooked resistors near the ICs, inspect the fuses that protect those two voltage sources or the regulating devices themselves.
