Hi, it seems like you are having fun! I would make certain that you have bought a identical board to the original first, this is a vestel power supply and there are a lot of variations, so scrutinise all the components,etc, If you are sure you have the right board then you probably have bought a faulty board(unless you are unlucky and have another fault). I dont know if you are an engineer or not,but my experience on these boards is that the majority of faults is usually a electrolytic capacitor faulty, if you have a ESR meter check each one in turn, if you dont have a meter, then look for a capacitor with a "bulging" top - failing that then your best option is to buy a repair kit for your original board.

hi brainstorm, thanks for the advice m8, i checked the boards when i got them and they were identical , no bulging caps though   :bo:
thinking about investing in an esr meter though.

i'm not an engineer . i'm just a novice hobbiest trying to fix my own set .

i've sent it to a guy to be tested now but i will post the results of repair up just incase anyone else has the same prob !

ok guy's , i sent my two faulty power boards off to a guy i met off ebay . he sells these boards  and other television parts . his ebay id is -  sparedparts , so check his ebay site for spares, he sells these boards for a very reasonable £45 + postage and is both a top bloke and 100% genuine .

unlike ebay member -  juraseknr who sold me a faulty board  :sad:

 sparedparts managed to repair both my boards for me  :clap:

and sent me the following results -

Board 1. which was blowing the 2.5amp fuse had a faulty bridge rectifier,

Board 2. was pulsing in standbye  - which was the power factor and regulator ic faulty .

hope this helps someone 1 day who has the same problem . many thanks to all those who offerd advice and help on this.
