Polaroid TLA-01511C 15 inch TV Picture Cuts Out

[radiowilbur]

After a few moments, my TV screen goes dark. The sound cuts out for a moment, but then continues playing, with the dark screen. I was getting nothing from this TV, but I then dismantled it to check the caps and note the numbers on the boards. I then reassembled it and it came to life, but only as described above......any ideas what is wrong or what I should check?
