My repairman tells me I need a signal board (Part# 930B827017). Part is no longer sold by dealer. Can board be fixed? If so, how do I find someone who can fix it? Or where can I find a replacement board?

Check for CRT coolant leakage near the vertical ICs heat sink( Board on Far Right when looking in the rear) . Very common problem. It will appear as a sticky residule on the circuit board. If you see any clean the area good with alcoho and then resolder the components in that area.
you might have leakage on the board from the tubes very common a few drops of fluid sometimes leak out of the tube just enough to cause crazy problems in set you need to check for this first unplug set and take the back off youll have to get a drop light or flash light so you can examine the module were the conversion ics are youll see a geen build up on module if you fluid leakage or you will actualy see on board it can be washed of very carefuly it will be the middle module as you face the tv from the back please make sure you have unit unpluged befor you look
Using the Mitsubishi remote, go to the locked function and when it asks for the code pres QV and 9 at the same time on the remote, this will work in any mode which may be locked, including entering a new password!
My brother had the same issue. I have the same set as well with this very issue. My brother had his fixed: repairman soldered the circuit board???? My brother could not tell me where on the circuit board or what circuit board???? IF there is anyone that knows about this....it would be helpful. I DO NOT WANT TO have someone else do what I can fix myself....besides by the time I pay a repairman I am 1/3 of the way or better to a new set anyway!!! Thanks a bunch - Pam
Everything is worth fixing provided the price is right. However, in this case it's probably not cost effective to repair the unit. Start with the easier fixes, such as bulbs, etc. Even then, some of the components can be quite expensive, or simply unavailable. I would suggest getting a quote from a local repair shop in order to make an informed decision before you get to far into it. You could end up spending just as much to repair it as you would on a new unit.
so does it have sound??? If so then the set is probably in a hv shutdown because of a weak tube or is in vieo safty mode as the vert has failed in the set. On cost here in Michigan a tube could cost up to 300 bucks + labor and on the vert repair about 250.00 to 400.00 to fix
