Hi, need help get service manual for Dynacord CMS1600-3 a very wanted audio mixer in India. I don't know why company does not publish schematic diagrams of the machines. Tried all web sites, could not find anything helpful. It has smps with microprocessor, available in the market but the software is not. Effect board is also costly. I will be very much thankful to get help. Thanks again.
Hello everybody in Hungary,
I am looking for schematic diagram of portable player THOMSON TM9670.
When I connect an USB drive into the machine, the normal supply voltage 5.5V drops to approx. 2.0V in dependency of each usb drive. The player reports that no usb is connected.
I found out that power supply circuit comes from transistor D882L – from pin No.3 which is base pin. This doesn’t make any sense to me. I would expect it should be connected to collector or emitor pin. Therefore I need schematic diagram or service manual for this player.
Thank you in advance for any help.
Regards,
smith666

hi.
a fenti rádiós szett-bár újkeletű- olyat tesz, hogy kb 5m után a vevő lenémít és vége.
akkut jónak mutatja, freki beállítások jók,minden egyéb beállítás is jónak mutatkozik.
leejtve nemigen volt-nem emléxenek rá -és nem is látszik mechanikai sérülés.
természetesen működött rendesen és egyszer csak lekorlátozta magát.
találkozott már valaki ilyen hibával???
üdv: egon
