Question about Philips 46PP9302 46" Rear Projection Television

1 Answer

Warping picture and color separation

The picture (on top and bottom of screen) is warping, and the colors on top and bottom of screen are separating. The picture in the middle seems ok. You recommended to someone else to replace Ic's. Is that the same problem with my tv? If so, how much do the parts cost, and is it possible to repair myself? (My husband is very handy). Our model # is 46PP9302/17F
Thanks

Colors are separated on the top from the left to right


Probably the color convergence is off. I had a similar problem. Have you tried the magic focus button yet? That is located at left in the small front control panel. Power on TV, wait 20 min (according to user guide), then press the magic focus. If that doesn't fix the problem, you could try the service mode alignment procedure. But that's a little trickier. I don't have a link handy for that procedure right now, but will look for it if magic focus doesn't re-align your color convergence.

Rca rear projection hdtv lost color convergence


Projection sets have two very common problems.

The first common problem is convergence


These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. This is called convergence.

When its out of alignment the video will look 3-D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the 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, Samsung,JVC,Philip Magnavox,Panasonic,Akai,Pioneer, Hitachi,Mitsubishi,Zenith and others.
You can get more information and a DIY convergenece repair kit with instructions from the link below.

Here are some of the most common problems with these sets...

*Screen Looks 3-D
*Colors wont align
*Screen may look distorted or warped
*No Audio/Video - TV Shuts down - May also make a constant chirping sound

Problem #2 - Another common problem is dull or washed out video.

Your set may have one or more of the following symptoms....

*Dull looking picture
*White looking picture
*Halos around objects
*Red/Orange looking picture

Warped Picture, Separated colors


Each color (red,green & blue) has an amplifier IC (STK-).
When there is a convergence issue,the first step is change both
IC's for reliability. Then check for open fuses devices,usually
pico fuses.Then re-check convergence alignment.......T.

Picture separated on 1/2 of screen


This sounds like a convergence problem. This is a common problem that is usually fixed 98% of the time by re-placing the STK392-020 ic or STK392-110, and check the fuse devices on the covergence PCB. I'm sure the actual parts numbers depend on the peticular brand. Good Luck!
