16-10-2015tv ctc195 beeps when i try to turn it on, does not turn onHi, my tv was on, working well, no issues. It made an odd sound that I had never heard before, then the picture went black. I turned it off, using the button on the actual tv, not a remote, then tried to turn it back on. It didn't turn on, instead it make

19-10-2015Thanks for that link mate, looked high and low for that. I have seen that other thread ( where I got my ideas from) but It he found a dry solder, I can not see anything like this on either board.

19-10-2015Was just pointing out the existence of that other thread and the fact that the Model codes may end in a different suffix - hence schematics may also differ. Person who found dry joint was NOT the OP. I think in end you'll find one or more output ICs

19-10-2015Hi guys, I'm hoping one of you on here may be my saviour. I've got an old Denon UD-M30 which also has the CD tray 'open' problem. Apart from this the stereo works like new, if I manually open the tray and put a CD in, it'll still spin up, read it and p

19-10-2015The 'ZERO' at the end of YOUR model number would be a LARGE clue. $1 / $10 / and a $100 bills are all currency, but the extra zero(s) make a HUGE difference.
19-10-2015Ok so here is where the dumb questions start.... What are the output IC's? Where should I be testing voltages between? Could you mark the points on the schematic for me? If I'm to much hard work I understand, just trying to self teach myself.
19-10-2015The reason I put it on this thread is because there were other people reporting the same issues with similar models and they seem to have repaired them successfully

20-10-2015Sorry, I don't see that. I See M3 / M5 and a couple other units that appear to be of different brands. Only one with a zero at end ... in next post he admits error.

20-10-2015Thanks mate your a legend, that is a lot easier for me to understand I will test it tonight and let you know how I go, I'm due for a new multi meter are the auto ranging ones better or just a standard one?
20-10-2015I have an auto range, but more important that you get switched onto the correct Function (DC Volts, Ohms, etc.). You can try to measure Ohms on the DC Volt function no harm/no foul, but if you try to measure DC Volts with meter set for Ohms, there could b
20-10-2015Thanks for that, is it safe to test the 12v and 35v circuits with a multimeter? Im not going to get electrocuted from it am I?
20-10-2015You should be fine. Just don't slip or otherwise connect two points together that don't belong together. Most dangerous area for voltages in that unit is going to be where the Mains / AC is connected.
20-10-2015Copy that! Thanks
20-10-2015Ok so Pin 1- 0volts Pin 7-34.7v pin 8-34.7v pin 9-34.7v This is with the D31 diode disconnected, with it connected the system does not start just get a flickering of the standby light.
20-10-2015... with D31 diode connected the system does not start just get a flickering of the standby light. (Everything connected normally And ... 12 volts present or not on pin 1? along with 34.5 volts present or not at pins 7 through 9?
20-10-2015With all connected except D31 diode i get Pin 1- 0volts Pin 7-34.7v pin 8-34.7v pin 9-34.7v That is only for a short time until it says protect on the screen and shuts down, with the amp PCB disconnected totally it will still read the same
20-10-2015So basically speaking, you guys are saying there is no similarity, so it's going to be difficult to find a fix?

20-10-2015I'm looking to see if you HAVE or DON'T HAVE 12 volts DC at Pin #1 of J3 (or pin #9 of CN2 at the SMPS)(There should be a jumper cable running from the AMP board to the SMPS board (at the Amp board it is called J3 ... at the SMPS board it is called CN2).
20-10-2015With D31 conected and installed there is no power at pin1 - no power pin 7,8,9 also no power (the machine wont power up with d31 connected. With D31 disconnected and everything else connected it will give me Pin 1 will read 12V Pin 7 w
20-10-2015All these were measured off the CN2 on the SMPS board.
