Magnovox 50 MV314X makes pop sound when turning on

[phil@philporter.com]

Inherited a dead Magnovox - model 50MV314X/F7. No signs of life - assumed it was power supply as this has been the case with about 10 I have previously repaired. A new board was less than the repair kit.
Found an inexpensive PS on ebay and installed. When turning on it blinks red like trying to turn on and then there is a brief static pop out of the speaker and nothing happens. Any ideas what might cause this? Don't mind getting a main board if it it suspect - they are only around $20, but if it could be something else would try that first. Thanks.

my guess is you have a bad main board. For prices like this it's a no brainer to get a new board.

Thanks. I agree - I ordered a main board for $20.

New main board and no change. Still blinks red light like trying to start and a few seconds later a static pop comes out of the speakers. Can anyone tell me how to check the power from the PS to the main board? Thanks

I suspected a bad PS since it is doing the same thing with both the old main board and new main board. Now it turns on and the Magnavox logo comes on and HDMI text at top left of TV, but after a few seconds it has that static pop out of the speakers and turns off. Not sure where to go, but this is a relatively new TV and want to give to my son and daughter-in-law expecting first child. Any help is appreciated. Would pictures help?
