sanyo model FV3982 intermittent sound but no picture

this TV works fine for a while and then goes to a black screen. Tore the back off of it and cant see any obvious problems. Any advice?

ok, I ran TV out of the outside case for hours. It worked fine and never went to a black screen with sound only. Only variable is that the garage is cool, around 50 degrees. I added some ventilation holes with a drill in the back near the boards and put it back together. I now have it playing in the house where it is warmer. So far, so good. Did anyone ever run into this problem?

in a few threads people have also added pc fans to tvs to keep them cool etc maybe if the set plays up again heat one board at a time with a hair dryer untill the set shuts off then concertrate on that board by heating a smaller area to track the faulty part.

Only variable is that the garage is cool ..piffle ..
how did it get there ? was the back removed making things more flexible before or after you moved it ? ..
if i was to guess it has a bad connection that will come back later ..
