The large IC's on a big heat sink is where the convergence ic's will be
here is an example http://www.nteinc.com/specs/7100to7199/pdf/nte7178_81.pdf
the resistors will be on the lines of these IC's
need help identifying the resistor values?

Having i think convegence board problems with my phillips model # 60pp9202/17F called tv repair guy said it was my convergence ..colors are alll orange and bottom of picture kinda bubbles up can i replace...


Replacing the convergence board will require a complete convergence adjustment. A better solution would be the replacing of the defective convergence IC. This would retain the convergence settings for the set. I'll locate the part numbers and costs and update this later.

My 'Philips 51PP9200D/37' TV picture is distorted and bowed along the bottom. There is like a "bubble". It has been there for over a week. It went away for the night last night but is back this AM.


Projection TV sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the video to look normal. When its out of alignment the video will look 3D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the TV 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, Zenith, and others. You can get a convergenece repair kit from the link below.

Common Symptoms include....
  • 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.
  • TV shuts off after powering on - TV may also make a chirping noise.
Here are some photos of convergence problems.

Here is a quick test....

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

Try to adjust the red and then the blue convergence.

You should be able to move RED and BLUE in all directions - up, down, left, and right.

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

Note: If you TV has as flash focus or magic focus button only try pressing the button. If it fails to fix the convergence your need to fix it. See below for a solution

You will need to replace the convergence chips and possibly some convergence resistors and pico fuses.
This is a a fairly easy DIY job if you know what you are doing. If you have never done this before we would advise calling a shop or if you want to do it yourself get a complete kit with instructions and support from www.TvRepairKits.com

03 philps 52' rear projection red and green lines laping?


Hi, I used to work in Best Buy and one of the key things about rear projection TVs and the reason they push those service plans on you is that the tubes/colors need to be calibrated each year. You can do this yourself by checking out the following website:  

http://lgknowledgebase.com/kb/index.php?View=entry&EntryID=3229 

If you are not able to adjust the convergence using the remote you will need to replace the convergence chips. 

Typical Symptoms

1) Convergence menu does not work for one or more colors.  
Such as: Red moves up,down, but left or right fails. 

2) Screen is bowed looking.

If you have one or more of the problems above you need to replace the convergence chips. You can get a kit and instructions from www.TvRepairKits.com  

Hope this helps :)

My Philips 51PW9363 looks like someone is pinching the screen in the middle from the top and bottom. No color, sound or other problems that I've noticed.


Your TV most likely has a Convergence Chip Failure ( common problem )

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.

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.

One of my colors are not registering with the others.


you will need to get convergence done to correct the color alignment and the warped look , those are the exact signs of the convergence IC's failing
will you be trying to do the repair yourself or will you be needing to call an electronic repair shop?

Blue convergence


DO you have 2 possible solutions

1.--Look under the CTR ( picture tubes) for leak coolant , all the times this set leaking, if is positive, use alcohol 90% with a bottle spray, clean the area, tied screws gasket ctr and let dry for 6 hours minimum.

2.--Loose connections on the left chassis ( convergence board), re solder ( look for possible resistor born)

55pp935217 Way too much blue


No sounds like the blue CRTs coolant has congealed and thats whats giving you the trouble. the blue tube get congealed and will cause the blue to not even show up properly in the convergence menu
