Could be a bad solder joint or a CRT getting weak. Check for bad solder
connections at the low voltage regulators and HDT, test and maybe restore
the CRT and maybe it will last a while longer.

okay this is the 2nd sony tv that is going bad on me this week.
If some can tell me if this is worth fixing.
It powers on fine, sound is fine but in about 10-15 mins, picture blacks
out. Sometimes returns in 5-10 mins WITHOUT turning off set. Will have
picture again if turn off set for 2-3 mins. worth fixing??
Thanks for reading.
