Initially the tv would make an arcing sound and lose power. I found CP031 had burned a hole in the board. I ordered the repair kit from Repair World and installed the recomended cap,trans. and diode. Now, the green led power button lights on for 11 sec. then goes out. There is no other reaction from the tv. Can you help diagnose this problem?

It's most likely the low voltage transformer that's part of the circuit board or a blown trace on the board. The HV transformer would only burn and smell if the unit was in a cook cycle.

The complete board assembly is only around $80. If you're really handy, you can order just the little transformer, but you'd have to remove (unsolder) the old one and install (resolder) the new one on. The circuit board is one assembly and it takes all of 30 minutes or less to replace from start to finish.

Check with Martin Microwave Inc. @ 1-877-894-0035 to order or to inquire.

problem doesn't seem to be on the power supply board only! had the service center check the high voltage section already? does the popping sound like the one popcorns make?
