sony trinitron 27 japanese

My TV Sony Trinitron FSS series has a sound/audio problem, at startup power ON, the sound is so faint (no sound/if audio volume is increased garbled sound), when operating the TV is prolonged, the sound will become good and clear...

Why is that? Please give me tips and solutions to remedy


Thanks a lot,

PS

I already have the schematic diagram, but where to find the fault?

First check if the problem comes from the Tuner .. This you can do by using a VCR if the problem persists .Then we know is not the tuner . The it could be the capacitors around the audio chip ,or the audio chip itself ! .

Usually tunners are hard to repair.Only if you know what you are doing you should try to resolder it with a "proper" soldering iron .Otherwise just replace it ..This is not hard .
If this is an old set .Is probably not worth it to invest money .So you can always use it with the VCR by using the VCR tuner for reception .And use the video inputs and audio in the TV ..
 

I guess that's that. Problem must be fixed.
