Question about Sanyo DS27820 27" TV

1 Answer

Sound cuts out periodically

Sound comes through normally when TV is turned on. However, it starts cutting in and out periodically, for longer and longer times. Sound comes back briefly (a word or a sentence) then goes away again. Tapping the set sometimes brings the sound back for a short while.

Re: Sound cuts out periodically

Sounds like a poor or cold solder connection in the sound circuit. If your not a tech, this repair really should not cost an arm and a leg to repair , but maybe your first born??LOLOL No really if you have no solid state repair experience please seek out a local repair person to assist you in this repair.

TV cuts off


Offhand, initial suspects could be:
  1. power supply;
  2. cold solder or loose connection (heat related);
  3. internal protection circuitry kicking in.
A couple of question pls:
  1. any burning smell or crackling sound;
  2. was there any power surge or interruption prior to the problem;
  3. anything out of the ordinary;
  4. during the the 75 seconds that it is on, picture and sound normal?
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.
