Hi Alex, unfortunately I have to notice, that the pot R11 2k Ohm is not the cause for that little problem I got with the power supply. As I described, I changed the whole part platine 99P0108-000 (where this pot is mounted on) and I'm still not able to start the unit. Nevertheles I tried to change the pot's adjustment - always at the opened unit so I didn't see the hole you described - but no results, it doesn't even make a single noise. The only thing which "talks to me" is the little 2x 10 Volt primary transformator, which I can hardly hear silently "buzzing". The unit's power consumption is roundabout 20 mA at 230 V here in europe. Normally after switching power on with 5 V standby the unit itself needs more than 100 mA without a connected Lisa and 0,25 to 0,35 A with the tube at max. brightness. But mine doesn't. I can't switch it on cause Q6 Collector is always on ground, due to the 0,7 V at it's Basis and I don't know why, cause I don't have a schematic of this type of power-supply. I have the 150 V at the two 470 microfarad after the rectifier, so the unit could work if it wouldn't be permanently inhibited.
CRY, WHINE: can anyone help me? Tom ---------- >Von: Alex <[EMAIL PROTECTED]> >An: <[EMAIL PROTECTED]> (LisaList) >Betreff: Re: HELP Lisa dead 150W Power Supply >Datum: Mit, 26.
