Hi I have a samsung le37r88bd tv {3 years old) that keeps switching itself on and off.
I've replaced 3 bulging capasitors on the psu.
Which solved the power problem on cold starting the tv.
However the problem persists.
Today it lasted 6 hours before fault started.
It is much more frequent when i switch to component input.
Any help will be great
thanks in advance

Ok guys I've ordered a new psu pcb for the tv.
Now the question is if I still have the same problem what else could cause it ?
Thanks

Well replaced the psu with a brand new one and the problem remains. I switch the tv on and its ok for 5 to 10 minutes then starts switching on and off exactly every 18 seconds. Any ideas please as i'm at a loss now as to what is broke and needing replacing.
Help
