As long as your convergence adjust properly the board has nothing to do with the new symptoms,yellow spots are associated with the blue picture tube,you can check for dirt on the face of the tube,you can check if the spots move like water when you move the unit to see if is short in fluid,be careful when checking with the back removed.You can cover the face of each tube to see if the spots are in the other colors.Let Us know if you need more help.

Hazy yellow spot in the left lower corner of the screen

It could be a cob web inside the tv or something laying on one of the guns, like a dead bug. If it's a cob web, you should be able to move the tv a little side to side and see it change from the moving air current. I would remove the back and vacuum off the lenses of the guns and look for cob webs. It's safe to touch and clean the lenses, just don't touch any electronics.If this doesn't fix it, it's probably fluid starting to cloud up in the guns or IC chip problems.

I have a convergence problem. My Sony KP-65WS510 has a picture that looks like 3-D and bows at the bottom and top of the screen. I already replaced both the IC's STK 392-560 (2 qty.) and check all six 3.5a...

You have a convergence problem. Here are some of the most common symptoms.
Screen looks 3D
One or more colors can't be adjusted when using the convergence menu.
Screen is bowed in but stationary.

Here is a quick test....

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

Try to adjust the red and then the blue convergence.

You should be able to move them up, down, left, and right.

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

You need to replace the convergence chips and convergence resistors.

Check the site www.TvRepairKits.com. They have put together a kit for your exact model. The kit includes a photo instruction guide, original Sanyo STK chips, convergence resistors, etc. Everything you need to fix it yourself.

Light green and pink spots on my hd tv!!!

Hi--Bought my panasonic pt-52lcx65 on sale for $2200 in 8/05. Replaced the lamp for about $300 in 1/08, just prior to Superbowl. Admittedly, this was to be expected after family members watched lots of tv over 30 months. However, two months later the blue spot emerged in 3/08, and red spot emerged 5/08. Set looks decorated by a Andy Warhol or Van Gogh wannabe. I'm looking for a fix it solution. Dr. Bob Heiliger, Lebanon, OH.

Light green and pink spots on my hd tv!!!

Tiny particles of dust on the light engine lens can cause this (and was a service call for me about a month ago), or possibly the expensive light engine.
