Question about Philips 50PP9202 50" Rear Projection Television

Color Set-up Problem

I have a philips 50pp9202 and the color is off. Is there a Factor Color set-up?

darylwildhog Sep 24, 2008

My set had the green color bowed at the bottom in the middle, and at the top outside corners of the picture. I kept using it, the n the blue went out. I replaced the stk392-120 IC's and the 6.8 ohm resistors, now the blue and the red colors are good, and the green is out again with some distortion in it. After a while you could turn the set off then turn it back on, and the picture would be fine. About 5 minutes later, the green color would start pulling up from the bottom left corner and would be back as it was all messed up with the green bowed. Must be something before these chips.I have a sam's photofact, guess I will check voltage points. Any help from anybody that has fixed this same problem and knows specifically what it is would be greatly appreciated.

This set has had many problems with convergence amps going bad. More than likely this is what is going on. You can take board up and look for a loose connection first and if not then resolder anyway, but you probably need to order the STK's 392-*** Not sure what they are in this set maybe 110's. Replace both and the 4 resistors that stands up next to them.

My philips dvp3560 will only playback in black and white

Check the TV System menu:

[TV System]
Change this setting if the video does not appear
correctly. By default, this setting matches the most
common setting for TVs in your country.
• [PAL] - For a PAL-system TV. (European TVs)
• [Multi] - For TV that is compatible with both
PAL and NTSC.
• [NTSC] - For an NTSC-system TV. (American TVs)

Also try:

[Picture Setting]
Select a predefined set of picture color settings or
customize the personal setting.
• [Standard] - Original color setting.
• [Bright] - Vibrant color setting.
• [Soft] - Warm color setting.
• [Personal] - Customize the color setting. Set
the level of brightness, contrast, tint and color
saturation, then press OK

Tries these settings the contrast full to the max setting.Set the backlight to the full max too.The rest sets it to the middle or to ur disire.
Because the contrast and backlight the most important in settings in colors adjusting.

My screen has gotten much darker

use the advanced options page and reset the factor blue and red convergence defaults then do re apply the auto color defaults color at first it seemed very red (which is good because red was the missing factor in the green picture) but after reseting all the color and tints to the normal ranges I then reset the color auto correct again and all seems fine.

I fixed that issue on my in-laws set - twice. Both times there was a different reason. First time, I went to the menu ON THE SET ITSELF, not the remote, and had to select an option. Don't remember what, but should make sense when you poke around. The second time was quick and easy, the cable company had swapped the blue and green component cable. Good luck!

Philips 50PP9202 50 in. Rear Projection HDTV-Ready Television?

Hello Anthony14,

This is an indication the the red convergence amplifier has goone bad you will need to replace the convergence correction modules. Now before replacing these you may want to make sure that the bias resistors and the zener diodes are ok. The convergence ICs are part number STK329-110 or STK329-150.

I would suggest that you get a schematic and equipment to make the needed tests, or take the set to a shop to replace the bad components.

I hope this helps,

Thank you,

Philips 50pp9202, no picture but sound is fine.

I have the 51 inch of this model and I have found that usually it give you some indication before going completely out. Like color problems, sound, or just video disappearing. Most of the time it will be the convergence amps going bad, but you should have seen some color distortion. If not then it could be the vertical output. TDA8177 needs replacing and check caps around and diode, If not this then look for open fuse in HV line to crt's. Also power supply fuse like 1900, 2004, 1300, etc.
