|
Hi I have just obtained a Promax MC-944 satellite / tv&FM spectrum analyser, It has a fault in that on power up it always displays low batt 5.5volts and then shuts down, I need to find a service manual or schematics for the thing, anyone help. The fault seems to be the power supply, it is a multi-rail output fed from a 12 volt input from wither a internal 12v supply or a 12v internal battery. The only numbers on the pcb are OCD0214, means nothing to me, Google has not helped either. I have emailed Promax, but as yet heard nothing in two weeks. Any help appreciated please. Regards FFr |
