Hi Davy,

Recall had a Vestel with no speaker sound. Chap had an elderly neighbour who kept banging on the wall so he used headphones in a rather energetic manner duffing up the socket - No speaker sound. Guess in your case something different as you note switching - Chris.

Yep, headphone got it's own amplifier in the chip and the switching voltage mutes the speakers.... I've checked the contacts as well on the headphone jack and all voltages seem to agree on the chip data sheet, checked from chip to speakers.

Half the time the Tesco Wonder Telly's sound are crap anyway, reckon a sound bar is the way to go or at least a audio feed to an amplifier, analogue audio is OK on the scarts.

Hi Davy,

'Tesco' tellies have recently got even worse, as they seem not to use Vestel as China is cheaper, and may work 'till the guarantee expires.

On the up-side, just had a couple of 32 LG where the sound is rather good but the screen Leds die like flies. Not an issue with Vestel small screen sets, not yet had a duff one smaller than 32 inch using a Vestel panel and LG Leds.

Good luck changing the chip, should be a doddle as has pins - Chris.
