Wharfedale LCD3210HDAF - no sound and slow button response

[jestah]

Hi,

I've recently had a real pain with a Wharfedale LCD3210HDAF tv.

It came in as the usual Vestel psu problems, ended up being a total re-cap almost, all the usuals, the 15nfs and nearby caps - and the caps around the 78L05.

I now having it running well, as far as picture, but no sound at all.
Power to the amp board is good, no audio input signal present, so must be the 17MB15E-7
When changing volume level up/down - that's when I noticed really slow button response, maybe 3-4 seconds of holding needed before action is done.

same for all buttons, I've pulled the button board and checked the switches (I was concerned as its from a heavy smokers  place) - I did change some as the switching was poor on some - no change to the response though.

Also when in no signal, it counts down in 2 second jumps - 4.59 - 4.57 etc is that usual? I thought not.

The psu is all good, so I'm suspecting the 17MB15E-7 eeprom next...
Does anyone have an eeprom dump I can try?

Thanks in advance,

Si
