Re: sony dav-sc5 power problem

It is power regulator ic and must be changed.
you must check around ic pins for short capacitor or burnt resistor to complete your job

No sound

Did you have storms go through your area and lightning strikes or power surges? We did a few weeks ago and I have very raspy sound but perfect picture...

How to connect other dvd or HDMI player into dav-sc5 for amblification

If your alternate DVD player has digital audio out you can make this connection via the 'optical digital in' port on the rear of the unit which corresponds to the Video 2 function. I have done this myself because the inbuilt DVD function in the Sony unit is dead (fixed once under warranty, problem recurred about a year later, same issue as other unsolved posts on this board, DVD function hangs, system won't switch off, etc. common problem with this unit, crap product).
