Hi Feenix,

That black disc might be a VDR across mains for spike protection. Note the chopper semi seems to have three pins so suspect a drive chip under the board - Chris.

Yes but no amount of heat brings a change in value which it should
Looked all over for a board and it is hopeless even used and breakers I will have a play after xmas but with the price of another is it really worth it

Well I got lucky or so I thought, someone won a Tevion 19" Hd usb and all that--- and I bought it cheap but despite a 3 yy warranty the picture is truly awful and no amount of adjustment makes a diff so I will be fixin my AS set in 2012---streaks ahead on picture and colour

What I have done before with an unobtainable power supply, is substitute a completely different one.

At the end of the day, it only needs to supply a few voltages (they even label it so you know what they are)

So first power it up with a bench power supply (you may need several) to determine the current requirements for each output.

Source an alternative generic power supply.

You will need to figure out some switching so the standby functions work. I used the "on" signal from the main board to switch a relay, via a transistor.

I did this on a Bauer XT32 a while back as the original PSU had a well known habit of self destructing, and I wanted something more reliable.

Hi Folks,

Guess our original chum has had some sort'a solution - he got lucky, as he said - who are we to deny his version of reality - Quuq folks are known to be cool and sometimes a bit whimsical, but ever total empathy - Chris.
