Had convergence issues, green was okay, red wouldn't move horizontal, and blue wouldnt move vertical. Also, functions such as pincushion and tilt wouldn't work with red or blue. Replaced convergence IC,...

This is a very common failure on these projection sets and a fairly simple DIY fix. All projection sets including Samsung, RCA, Sony, Philip Magnavox, Panasonic, Pioneer, Akai, GE, JVC, Toshiba, and others at some point will have the same problem.

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. Power light will blink. TV may also make a chirping noise.
Here are some images of convergence problems.

Our Philips Model # 51pp9303H/17 TV has alot of green/red which appears to be double screen appearance. When on the guide page for cable it looks like it is double as well. Its like looking at a red and...

Yea its a convergance issue. I'm more familiar with the sony bigscreens. The convergance amplifier number for that one is STK392-120. The schematics show that your tv has two of them.

Go here for a service manual:

You will see a window that says file information, at the bottom you will see something that says multipart 0 1 2 3 4. You need to download all of those files. you will also need WinRAR to unzip them. You can download a free trial of winRAR.

Once you have WinRAR and the files open part1.rar and it will unzip everything into a 1800 page pdf that is the service manual.

If you have a work copier use that to print the manual or use the pdf search function to locate the STK392-120, or 7044 and 7055. The latter two numbers are the numbers philips uses to identify the chips in their schematics.

I know its a lot of info, but I hope it can help.

Convergence issue

Not sure how service menu will help you other then to do more adjustments such as 3D reform and such. Not real sure, just a long wild guess but the coils on the picture tube could possible be loose enough to change positions when heating up causing picture alignment to change. Might be a cheap service call.

Are the colors out of alignment and unable to converge back? If so its the convergence ICs need replacing. If the convergence isnt out of alignment you have whats called a pincushion problem. If you would like a link to where you can obtain the service manual for this model let me know.

Convergence problem with philips 60 in.

depending on how old it is, it will either have a special menu (you will need to enter service mode to access it, need model number for that), or a panel in the back that you remove a few screws to gain access to. If it is the panel in the back, you will see about 20-50 little potentiometers, that have a slot in the top. Go to Radioshack, buy a TV alignment kit, stock number 64-2230. The pots will be in rows and columns, usually...and they should be labeled. Find the column/row for the red, and the pot for pincushion, which is the issue you are describing. With someone looking at the TV, and it on, turn that pot until the pincushion looks normal.

Pincushion Picture on a big TV screen!!!

The set has 3 IC's(one for each color)strictly dedicated for the aligment of each color,if one them does not align is because is going bad or is already bad becuase picture can not be adjusted,the IC's can be identify because they are mounted on a heat sink and have the markings STK--- ---,they are all the same and need to be replaced with an exact replacement.If you are familiar with tv service you can replace them,sometimes the new ones need to be aligned from the service menu,you will need the service manual,soldering and unsoldering will be involved,If you are not too familiar be safe and seek the assistance of a servicer.
