I have a magnavox 55" model #55p8288, and I am wondering if the IC convergence boards bad. The TV has blue halos around everything and is bright. When I goto converge under the menu, the red works every way, but the blue does not move at all. If you can help me find out if this is the problem, where I can get a replacement, for how much, it would be greatly appreciated.

Thank you very much.

James,

The SSM panel part number is 313503710431 and is available here http://www.andrewselectronics.com and here http://www.mcmelectronics.com as are the STK392-110's if you have good soldering skills.

Be aware, the Blue Halo symptom can be interpreted two ways. This model is known for its fluid contamination problem which produces an OUT of FOCUS halo which is NOT a convergence problem and due to being out of focus you cannot see if it adjusts or not. If the blue is IN FOCUS and the halo is only on one side or the other of the center cross it is a convergence problem which the above information will correct. If you choose to replace the STK's inspect the light blue or gray resistors close to the rear of the circuit board that stand up 1/4 inch for being overheated or burned up as a result of the failed STK's.

Either way, be aware that changing these parts is kind of messy. (lots of torex screws and some are hard to get to, and lots of harness and the SSB pcb mounting is fragile.

Suggestion: If you want to try this, use colored marker pen's to identify connectors on any that you might be worried you will not remember which socket they go to.

Hope this helps.

James,

Sorry,
The SSM panel is the left hand board when facing the back of the set. it is the bottom board with all of the daughter boards plugged into it. It has a large heat sink on the rear right edge that is host to the STK's.
