They won't power up properly if the battery is not connected. Yeah, looks like the diode has suffered some distress. If you cannot download this file, try it with or browser.

Getting back from that sort of failure is pretty difficult unless you have a copy of the existing calibration constants and firmware version. Előre is köszönöm a véleményeket, ötleteket! The batterypack now measures 25,6V at idle, which is fine and dandy. Always try to determine the cause of the failure before replacing the failed bits. This only applies to the big transformer based units, I have no experience on the really new ones. A biosba belépve minden rendben, amíg ki nem lépek nem fagy le.Next
Have you put a meter across it to see what you have on the pads? Great idea to power it via a current limited supply, after the fuses are replaced. Azt írja, hogy sikeresen kapcsolódik, de nem lát semmit, üresen jelenik meg neki a mappa. As said above, the unit powered up after charging the batteries. The blowing of the fuses is characteristic of the switching mosfets failing. I'd maybe look at 1n914's or 1n4148 rather than a 4007, but whatever you have on hand will probably work.
Picture attached Does anyone have a clue, what type of diode that is blown? Instead, contact your nearest service center! Please, do not make a copy of the downloaded manual and do not offer to sell it, just use personally to repair defective appliance! I usually start with about 12W and work up from there. Még nem javítottam ilyen szerkezetet, most szereztem hozzá akkumulátort, mert ami benne volt semmilyen feszt nem tudtam mérni. Tried to disconnect it from mains, power it down, remove the batterypack, and let the caps be discharged. Maybe the caps are charged via a resistor, when on mains? Hi, Can someone help with a service-manual to this unit? We powered it up the other day, because he needed it now. If you are not familiar with electronics, do not attempt to repair! I'd hazard a guess though that the diode did not go up in smoke on its own, and there is likely an underlying cause.Next
Állapot: Az adatkapcsolat létrejött, várakozás az üdvözlő üzenetre. The resistor failed because it's actually a badly designed circuit which runs the resistor in excess of its rating and eventual heat related failure. You could suffer a fatal electrical shock! Aspire737 Edit: after a long day searching the internet I finally found the right schematics. That way a shorted component won't go up in smoke, it'll just light the bulb. A bit like don't replace the fuse until you figured out why it blew.Next
This causes it to power up thinking its a completely different device like a 110v 60hz unit and that makes things go haywire. Ja, és az illető külföldön él, tehát nem Mo-ról csatlakozik. Replacing the diode with something bigger or stronger may well just move the failure point to the next weakest component and let the smoke out of that too. Ha kicserélem a processzort egy Sempron egymagos procira, akkor teljesen hibátlanul működik. A címben említett alaplap az eredeti Athlon 64 X2 processzorral 5 másodperc után kikapcsol.

The transformer isn't that big. És ha hálozat kimaradás van akkor nem kapcsol vissza hanem továbbra is az aksiról megy, mi lehet vele? The fuses did blow when i attached the battery and the caps was bleed to 0V. Anyway, I can replace the fuses - But another component is dead, probably a diode picture attached - The question is, was it blown before i reconnected the batterypack, and is it that thing that causes it to beep? Most csere után, ha nincs 230V a kimenetén 200V-ot mérek, ez normális? Totalcommanderrel és Filezillával is próbálkozott.
