Hello, for a few years now this tv has had an intermittent fault. At random times it switches off and begins power cycling - the samsung logo appears, and I can hear the relay click, as described in other threads. If I leave it for a while it will often stop cycling in this way and sit with the LED blinking. It alternates between these two states at random intervals.
For some reason, punching the TV in the lower right corner usually resolves the issue for a while! This can fix it from anywhere between 2 minutes to several hours. This even resolved the issue for around 6 months with no trouble, though recently it has reemerged.
I haven't tried repairing a TV before, but my first thought was dodgy capacitors, so I checked and couldn't see any obvious issues. The fact that giving it a smack repairs it would suggest a bad solder joint or similar, but I don't know if it could affect components in other ways. From reading around the forums these symptoms could tally with a bad voltage regulator?
Unfortunately I can't provide pictures right now but will do soon. Thanks in advance for any advice.
