Sceptre x320bv-hd Megmeet mp116

[tom thumb]

Ok so here is what it is doing
Turns on but the sceptre logo has a slight flicker when starting
Tv runs for about a minute with perfect picture then screen keeps going on and off

5v line =5
pson =4.63
12v = 11.7
24v = 24.0
When tv goes off the 5 volt line and pson are fine but both the 12v and 24v
line are turning off and on and the screen says no signal as if it is resetting

So is power supply to blame or is main board shot.
It acts up within a minute so not sure if heat is a factor but I am not sure if this is a sign of a bad cap or not

Post good clear pictures of the boards, it sounds like the power supply board problem in the 12V/24V SMPS section due to bad solder joints, bad caps, or the inverter board is drawing too much current, etc.

Sorry cant send pics so i will have to just wing it all caps appear fine replaced a couple of them anyway and still same problem and problem still exists if I disconect panel lvds
One cap was replaced before and it was soldered on the bottom of the board
instead of through the holes but that should still not make any differance

Update If unplugged for awhile to discharge caps it will turn on and keep working
turn it off and on several times and it works fine

But unplug it and plug it in b4 caps are fully discharged and the pic goes off and on within a minute
