Re: Sceptre X32 stays on for about 10 minutes, then turns off.

I replaced a Sceptre 32" X320BV-ECO for a Customer that was turning off after random amounts of time with a screeching sound until it was unplugged.
The TV had been shutting off after progressively shorter times over the last month. It would not shut off or reset without unplugging it.

When i opened it I noticed swollen Caps on the Main Video Board.

1st one is by Power Supply feed header in between Inductor and Tuner (Cheng 1000uf 10v). Barely noticeable but very dead.

2nd & 3rd are by the Speaker header (Cheng 470uf 16v).

HOWEVER... In my haste to measure power supply voltages... My meter lead hit the supply leg of the Back light Mosfet (FDPF-5N50FT) promptly shorting it out. This caused MEGMEET MP320P to throw a self protect Blink 7 times Code (Onboard Diag LED). So I replaced the Mosfet and the bad Caps with their 25v versions. Put everything back together and It has been running perfect for 8 hours now. Before repair it wouldn't last 5 min.

Referencing above pictures 1st one is CE5 1000uf 10v. If buttons on TV stop responding and TV won't shut off without pulling plug. Check this cap for low uf reading.
