What have you tested so far?

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,

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 board
