samsung lcd LA40M81BDX

[Hillbilly]

I have a 40" inch Samsung lcd tv which is starting up,then shuts down then back on again. It did this before and the caps on the power board where replaced,now it is doing the same again. I have tracked it down to the main board which is around $400. I found a fellow in Sydney who can fix it for $100 but he wants me to take it there. I live in S.A, has anyone fixed this problem on the main board

What caps did you use for replacements? (Or if you had a tech do it, what caps are in the PSU right now?) If lower quality caps (i.e. not low-ESR) were used, they could fail after some time.

I have replaced the caps for a second time and also tested the PSU in a second Tv which works ok just to make sure it works.

Did you replace any caps on the main Board?
