Re: Samsung LE46M87BD
Been testing all input on main board, still turns off and on no matter what input is used, but only when using freeview will the picture freeze for upto 30 seconds before turning off,
Looks like someone has been in here within the last few weeks as had some caps replaced and there clean with no dust,
I have i soldered them to check and even though that are cheap and nasty caps, that read fine.
Looking like a main board fault, as all readings from power supply look good,
I'll get some pics up tomorrow, as can't get them to go up here on the phone,Attached Filesif you find these attachements useful please consider making a small donation to the site

Re: Samsung LE46M87BD
One possible cause are cold solder joints, hit slightly the pcb with a screwdriver's handle and moove connectors while ON to see changes.. especially the main boardLast edited by Davi.p; 01-17-2015, 09:03 AM.Comment

good morning, I have a samsung UE55F8000SZ tv that turns on, shows the logo and turns off after 1-2 seconds.
This defect happens continuously, hearing the classic click of the relay every time.
Power supply board BN44-00636B
disconnecting the mains and lamps from the power board always causes the same problem.
Is it normal that without anything connected this power supply turns on and off cyclically?
any suggestions on what to check?
thanks in advance
