Hi, friends! I need, if someone can help me with schematics diagram of this power supply.I changed all the capacitors on the power and C380 on the mainboard, but after it warms a bit, stops, starts again and the process repeats.Thanks in advance, from Cluj-Napoca, Romania,alll the best!

Hi ANDRASONI,

Very astute of you to replace C380. I have the service manual for this model, but it's totally devoid of schematics. Only suggestion I can make is to replace the capacitors near the series regulators on the main board. Strange, C380 usually cures most problems in these as a rule, but I guess that model is now ageing.

Perhaps our man in Slovenia can help with a schematic from his Strahov library.

noroc bun, Bruce

PS: I believe there is another 100uF below the big heatsink on the main board near the voltage regulators (possibly C480), that should be changed, along with C414 (470uF 16V) which you may have already changed.

Yep, that's the one, Flash Jordan. Transilvania, you say. Isn't that a hangout for disgruntled vampires?

I do not know how to see Transylvania from your home ... I can tell you is that Bram Stoker had a vivid imagination, Vlad "Dracul" (Dracula) was not really that evil and Transylvanians are special people ...All the best!

SM dont exsist
On main board replace two electrolytic capacitors C-348 and C-350 (all 100uF/6,3V)
Allso check three 330KR SMD resistors in series in the PSU which supply voltage for DLA 001 (check if resistors are high resistance)
