Fisher tv monitor intermittently turns to snow and loud buzzing

Fisher Standard TV is about 20-25 years old. Intermittently picture turns to snow with loud hissing sound. Usually after a few seconds it clears up and picture and sound come back. Other times, turning it off and back on with the remote clears it up...and sometimes have to turn it off and try later.

Could it be vertical IC loose connection. It is sometimes connected with correct tuning. Check it for crack or wiggling connection best is to resolder.

No Sound from Fisher Box TV


I think your problem is with the scart socket . It most likely to be a dry joint on the pin where the sound goes in to the tv. you have to take back cover off the tv and turn the chassis over to do the dry joints if you can do it yourself otherwise get an engineer to do it. Good luck.
