Question about Philips 55PP9363 55" Rear Projection HDTV-Ready Television

Multipoint (Blue) Off

My television gives me a headache now when I watch it, because I have blue halos all over. Everybody has a blue shadow above or on the side of there head, and objects are the same way. I have tried fixing the multipoint, which does not work. The arrows are hard to push and once you fix one side and go to the other side, the first side you fixed is off. I am ready to throw the television out the door.

Re: Multipoint (Blue) Off

It sounds like the convergence amp need to be replaced. That unit is a DPTV335 chassis and IC 7044 is an STK392-120. That together with all feed resistors for that circuit need to be tested for change in value.. Before doing that you might also check to see if the blue crt yoke is up tight in place and not tilted. Have you moved the TV at all recently, before this problem happened?? If so the yokes on these units have been known to slip down. You can look at this yourself by removing the frony covers and exposing the CRT area. Look at the blue yoke, comparing it to all the rest. Make sure to do this with the unit unplugged. At the back of the yoke you'll see a set screw that clamps the immediate rear of the yoke If the yoke has slipped it will be noticeably lower than the rest by comparison. If ANY of this sounds too complicated it's shop time. But replacing the repair to the convergence circuit isn't difficult. You might also ask as you're calling around the shops if they have that STK on-hand.. Also, take the unit in and you'll save on the cost of having the shop transport it... Good Luck Bill

I have a yellow line on the right side of my Toshiba 50 rear projection TV and yellow shadows around people

It sounds like a convergence problem---go into the customer menu and select convergence---set should offer center and multipoint adjustment--in the multipoint look to see if the outer crosses adjust--if red or blue will not adjust somewhere--bad convergence IC's.

Picture has a blue shadow

Seems convergence out IC is fried in TV so it gives blue shadow.

Check out Convergence Out IC which you need to replace in TV, if you have enough experience of repair of big TV, necessary tools and know basic electronics.

Blue Multipoint converge failure Philips 55PP9753

The most likely cause is shorted convergence chips and possibly a few pico fuses.

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,Pioneer2_bing.gif Hitachi,Mitsubishi,Zenith and others.
You can get a convergenece repair kit with instructions from the links below.

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

Problem #1) Convergence

Yours may have one or more of the following symptoms...

*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
