Question about Philips 43PP9202 43" Rear Projection Television

1 Answer

PHILIPS 43PP920217 DPTV305, no video feed after Conv IC Install

Essentially, got the tv for free, the convergence was all messed up so I replaced the factory STK392-120's with the same ones put the thing back together and now i get all my projectors lighting up but can't get any actual video feed out of it. I can change channels and hear them fine but no video feed other than a mix of the colors with no changes. So I guess I'm trying to figure out where to go next, I checked over all the boards for blown anything but can't find a single thing wrong. Anyone have any ideas where to go next?

Have an Hitachi 51UWX20B that has the 3D thing going on, when I adjust it manually, and exit, the TV wont let me save, cancel, reset, or go back! Have to turn TV off to get out of that screen. Any advice...


Do not adjust any knobs as instucted in the previous thread if you TV have a convergence problem. Doing so will only make things worse. The blog does however show you how to fix other common problems with these sets.

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.

Here is a quick test....

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

Try to adjust the red and then the blue convergence.



You should be able to move them up, down, left, and right.

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

You need to replace the convergence chips and convergence resistors. Check the site www.TvRepairKits.com. They have put together a kits for most models. If you don't see a kit for your set send them a quick note and they will put one together for you. Their kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, etc.

Convergence problem


did you replace the six convergence resistors with the ICs? as Hitachi recommends replacing the six resistors when the ICs are replaced as the old ICs can harm the resistors and they will need replacement.

Convergence issue


You can go back to factory settings by pressing and holding the ACTION and POWER buttons on the TV while it is on. A CHK screen will appear and when it does release the buttons and then power the set off then on again. This had reset all settings back to factory conditions. You will have to reprogram any channels into memory after this.
