Try replacing N-channel mosfet transistor 2sk2518. I had the same problem, and it worked for me. It is located on the convergence board.

There is a very good chance that the fault can be in the power supply, and or one of the scan circuits are failing, due to a few parts that have come off their values. These types of faults are due to age and use. You should call in a service rep who is familiar with your make and model of set. He would be able to give you a proper estimate for the repairs. Some of these repairs are very reasonable in cost, while the more difficult types can be rather expensive. Hope yours is the first case Good luck

IQB64W10W high-def problem

Your problem sounds like the digital board and probably was what the repair people said. I would suggest telling them about Tri-State Module, Inc in Evansville, IN. 800.203.7484. They have a good selection of modules for about any set and most are under $150.00 with the average being $100. They rebuild boards and all boards carry a 12 month warranty. You can also access them at If they can't help try PTS in Bloomington Indiana. I use them for alot of replacement modules. Same deal as tristate.
