Question about Audio Players & Recorders
The screen only lights up on the right hand side the information screen does not come on and there is no sound output because the main controller isn't powered up. the heat sink inside the unit is heating up.
If you could be of some assistance that will be great thankyou Rodney
Have a look at the following. 1. Check your supply to the frnt panel. You ma have some power there but also look for a Resistor that will mesure open, and look for a Reulator. This will be fitted to a heatsink, not a big one though. If there is no heatsink look for the transistor on the main heatsink starting with la78XX. The last 2 dig should give you the power it is letting through. for expl: LA7812 will be a 12V+ regulator. A LA7912 will be a 12V- regulator. If nothing is found on the front panel check for this on the main bord. Once you get this right you will see that your fron panel will switch on and the controler will also switch.
Now for your heatsink that is still warming up. Disconnect your power to the main Transistors. You can do this by desoldering all resistors that is going to all the transistors. Your supply is going hi and your transistors is getting hot.
I know all the above is much but try it.
