HELP!! Bush LT26MC1A

(1/2) > >>

Geoff S:
Any help would be appreciated on a BUsh LT26MC1A with a 715T2907-2 psu.

The set responds to remote or manual switch on IE The standby light switches from red to blue and that's it, no backlight no sound. I have to switch off at mains to get back to standby.

Upon inspection I found the 12v reg IC had failed. After extensive searching I obtained and fitted a new one which has got the 12v back up but the set behaves the same. I'm thinking eeprom corruption. Any thoughts? Customer is starting to get restless!!

Cheers

looks very like one I've been working on came out an acer 26 inch found the two mosfets on the left hand side of the primary were faulty although not shorting which is unusual they weren't passing power either.... worth a stab takes 10 mins and a steady hand to change !
