Its better to get the schematic diagram or a similar one to be sure, but the reason for a blow up may have to do with a s/c along the line.

Is there a way to make the sound of the reverb on my deville 2-12 sound better ?


modding the reverb takes some electronics experience...if you know where the reverb circuit is. all you can really do is change the input caps that make the tone bright or dull... larger uf for dull... lower cap values for bright... it's in the signal circuits... dont mess with power caps. The schematic shows op amp into the tank and out of the tank to another op amp...Output of the tank to opamp.. Id double that input cap ( 330 pf ) to see if you get more response into the opamp... then look at the circuit C17-C18/R33-R34 894cf4a0-46f7-4f21-9667-be620f05b31d.png

You would have blown the fuse. There was a reason why the fuse had blown the first time. Being that this unit is self powered. I would look into the power supply board and look for blown caps. Hopefully you didn't burn the board. Most times a problem like this is a bad Capacitor. Look for blown Capacitors on the board. They will Look like little soda cans. They would be buldging on the top of the cap and possibly leaking yellow or white if bad. Capacitors should be FLAT not having buldge at all. Replace Caps with exact uf EXACT on the Volts you can go over what is printed on the bad Capacitor but never go under. Caps can hold a wallop of a shock and possibly kill you. So either you or a pro discharge the caps. They can hold a punch and knock you on your but. Even unplugged. So Discharge them and proceed.

It just turned off by it self and it wont turn on


TV is in fault protection mode. If the TV relay clicks on then off and the Fault LED starts blinking. You have bad/blown capacitors on the PSB-Power supply board. Recaping the blown UF caps works 90% of the time.

Re: Onkyo DV-CP500 DVD player stuck in standby mode (by 7 users)


Hi Yes, sorry just saw this comment. Swap out C7, C17 and C18 in the power supply. Also I would check if you are getting 9Volts to the motor control IC's pin 7 coming off of C005 on the Mechanism Board which is under the unit. The hole for the C005 cap was drilled into a very narrow section of the circuit board and has marginal connection at best.. mine stopped working because of this 6 months after I fixed the power supply.

HCN4727W with Convergence issues


Mike,
The ICZ designations on that board are two Sanyo STK392-040 amps used for convergence. Rz142 through Rz145 are the yoke return circuit are 3.9 ohm 1/2w resistors. CZ140 and 141 are two electrolytic radial 22mf/50v caps in the feed circuit for those amps.
My question would be - and I've NEVER seen this, in my 30 years in electronics, what caused such a domino failure? The amps are basically LV fed by a +/- 24v line input. If the yoke(s) were to short shouldn't cause enough feedback to destroy the convergence board in the manner you've indicated here. That's a P58A chassis used in several models of the Samsung and Akai designs. Only trouble I've heard of with those boards are cooling and most techs have taken to installing cooling fans directly on the board, driven by the +/- 20v line. That drops the temp several degrees and allows the amps to operate at a much cooler temp. We rebuild those boards here on a daily basis and add the mods for greater reliability. But other than that the P58A is considered a bullet proof chassis.
Hope this helps!
