Hi romanko
The IC is actually shown as a MP1593 on the schematic, but not sure if the associated components would be the same values for a MP1593. Not easy to tell without markings on the components or the board. Probably worth a try if you`re good at soldering, but keep in mind that you may need to fit the right IC to avoid confusion over whether or not you can use a `93.
Regards
John.

Hi Guys
Was given one of these sets recently with the problem where U696 needs a dose of the hairdryer to start it and spent a little time scoping waveforms. Ended up with the 'assumption' that U696 couldn't deliver enough current at 'power up from standby' to get the set started. Got round the problem by adding a 1000 microfarad low impedance type electrolytic capacitor from the output of L 107 to chassis. ie across the standby 3.3 volt line. Found then that the set started every time. Don't know if this would always work for this problem, or if there is a better solution. Anyone have any further info?
Regards
John.
