hi...your convergence IC's have gone bad.
These IC's operate at a very high temp, and usually only last 4-5 years.
If you remove the back of the set, you will want to look for the
BIGGEST heatsink in there, on that heatsink, you will see 2 large IC's ,
probably STK392-040, or STK392-120's or something close...regardless -
you can go on ebay to order the new ones, but MAKE SURE they are
Genuine SANYO IC's and not counterfiet cheapies. the cheap ones may
only last 2 months..
You will also need some "Heat transfer paste" - you can pick this up at radio shack.
Once you remove the old IC's, test all the large resistors near
them.. pull one side of the resistor out of the board so you can check
it out of circuit. they will usually have the value in Ohms, printed
directly on the resistor, but you may have to use the resistor color
code to find out what value they are....However, usually if there is
any damage, the resistor will look like it has been HOT or fried.
replace the IC's and any bad resistors, and you should be good to go.
If after replacing the IC's and any defective resistors, the
convergence is still bad, make sure to use a multimeter to check ALL
fuses on the boards, --- sometimes when the IC's go, they will take out
a fuse to the convergence power supply. If you find any bad fuses,
replace them accordingly!
Hope that helps u alot...
thank u!!!

Hi,assuming you have the volume up on your receiver, and on your TV, the
problem must be in either: The A/V sockets on your TV = try another
set of sockets (eg: AV1, AV2, AV3,etc)
The scart-to-AV lead supplied with the receiver = take it back to your supplier.
The receiver itself = take it back to your supplier.
Note,
though, that some new TVs have so many A/V, Component, S-Video sockets
on the back that it is hard sometimes to work out which audio sockets go
with which video socket, so you may have (for instance) the yellow
video plug in AV1 while the red & white audio plugs are in AV2.
Hope you're able to sort it out.
Also, check the 'mute button' if your using those cheap black scart leads,
please get rid and buy better ones as they are only to get you started
and wear out quickly hence your problem..
You can do the old Sky trick of pulling the power cord out for 30 seconds and that did the trick.

I think you hit the wrong button before....
To restore the settings please try to restore factory setting and see what happen..
