Re: Benq BL3200PT with a cooked PSU.

So I coulnt find a SOD-80 packaged fro the diode suggested by the application note, so I just picked another "small signal node" in that package with slightly better characteristics, and I'll just have to hope it works!
Resistor I've 'decided' is 10K, more or less inspired by a schematic from another BenQ supply. it seems these supplies change the DC-Dc and various bits, but most of the drivers and passive stay the same, so I'll just have to hope it works!

Re: Benq BL3200PT with a cooked PSU.

Hi, turns out I have /exactly/ the same problem with a BL3201PT screen -- same damage, same location after 5 years of use.

I've JUST managed to decode the label on the driver, which lead me to this thread; but I spent some time trying to probe around the board and discovered that 2 of the SMT diodes underneath the board are shorted in my case. As well as the crispy resistor, and very likely the driver itself. FET looks OK but definitely looks a bit sunburnt.

I found some replacement ICs, replacement FET, but I still...

Hello, I live in the UK and have somehow embarked myself into restoring/fixing vintage Macintosh and other bits and pieces. I'm more of a 'digital' guy but I've had to deal with quite a bit more analog lately and I can certainly use this forum for help!
