    They are located in the middle picture above. Those are the two huge black ICs with the spring clips holding them against the aluminum heatsink on the very edge of the right side of the middle pic. They are STK392-120

    just check the 6.8 ohm resistors right next to those ICs often one or two of those will be open, remove one leg of those resistors out of circuit to check them.

My big screen magnavox tv shows double lines red and blue


Model number listed here unlikely to have this issue which sounds like a convergence problem.

Oct 21, 2012 | Philips Magnavox 50ML8105D 50" HDTV DLP TV

I have some distored blue color across the screen


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

Im having colour problems with my phillips 43in hdtv blue and red lines across the screen tried to aligne but didnt help any ideas wat i can do



This sounds like convergence output IC problem. convergence board would have to be removed - remove and replace 2 STK IC's and check the surrounding resistors. Shops usually $200-$400 Be sure to vote/rate me if this helped Thanks!

yes the convergence ICs need to be replaced they are both STK392-120 ICs and you will also need four 6.8 ohm 1 watt resistors you can get replacment ICs and resistors at the following link and they provide free instalation instructions with pictures and free on line instant messageing to help you do the repair yourself. Heres the link.

55 philips replaced ic's as suggested and still red /blue around everything...


Now the heading list your model as 55PW9363 Which model number is your set? If the resistors arent open it has to be a pico fuse, But I wasnt aware that the DPTV series have pico fuses, they do have fusible links solderd directly to the circuits. Let me know your accurate model number. I was under the impression it was the 55PP9352/17 which is the DPTV305 series chassis or Mag01 which is the same except for magnavox

55 hdtv philips having issues with blue and red lines around everything ......


www.electronix.com should have them for about 10.00 each they involve soldering and dissasembly of the convergence board. A repair shop will charge between 300 and 400 to do the repair depending on where its done.If you go to the link enter STK392-110 in the search box and that will show you what they look like yours are either 392-110 or 392-120s they both interchange with each other, however STK392-120 are a better chip.

change the convergence ICs also check the resistors right next to the ICs as 1 or 2 of them may be open as well.

Sounds like the blue convergence IC s bad. They are relatively easy to replace if you can solder they cost around 10.00 each and you should change both the red and the blue.

Picture shows only about a 2-3" blue,green,or red vertical line down the middle


If your seeing vertical line across the screen you need to check the components in the vertical stage as well as the vertical IC could be bad, or the yoke could open.
Also check if any voltage reaching the vertical stage.

Good luck.

Was this help full.
