I have a magnavox 42mf231d / 37 it turns on

Hi tt3nry,

Unfortunately the answer isn't a simple one on that set. Just about every board in that set can have a problem that causes it to shut down. The cheaper way out this will be a trip to the shop as opposed to you buying all the boards from a distributor and doing it yourself. A small, local shop will charge you a FAIR price and do it right for you. Plus, most distributors DO NOT WARRANT parts if you are not a professional technician.

Ask friends where they have had work done or call the local chamber of commerce. They can point you in the right direction as well. Avoid the great big places. More than a few techs means more overhead and higher prices.

Good luck.

My Magnavox 42" plasma TV purchased from Home Depot also went out last night.....No picture only audio. What a shame! looking for a posible solution

power supply board - check the fuses first --- remove all cords and power cord -- wait one day then connect -- if this doesnt work -- you probably need a new power supply board without looking at it - can order online at partstore.com

relay clicking is a power board failure --- part of the board still works to supply power to the flashing lights--- the lights are related to an error code while in protection mode

42 plasma tv model42mf230a/37 blue light on no picture no sound

with solid blue led set could be still powering on but would need to verify by checking power supply voltages. if up and signal is present with no menu or audio would be ssb as audio amplifier, micro processor and eeprom are on that board. if voltages are not present you need to offload x and y sustain boards one at a time from power supply and check voltages and if vs comes up with either board disconnected replace that board
