I also have a fried zd3 on my boston acoustic mcs 95 Sub amp board. Do you know the radio Shack part number you used and did your amp power up? My Sub is not working. No power and no green light but my...


zd3 is a zenna diode, you will need to find the volts that it triggers at, most amps (99%) have a mirror circuit board so all components are dobbled so this will help you find what you need Re: Jeff

My Pioneer VSX 820K will not turn on. Son sprayed some windex on it when it was on and it shut down.


More than likely the windex fried a channel or two. If you have a DVM you can find out wich chanel or channels is bad by checking each output transistor for each channel until you find the one that is shorted.

MCS 95 SUBWOOFER WON'T POWER ON..REPLACED FUSE WHAT ELSE TO TRY


Concerning the Boston Suwoofer not powering up, I just had the same problem and this is what I did to fix it.

1. Uplug the unit
2. Remove the outer screws and remove the board unit
3. Unplug the board (Power Board) that is connected to the switch and unplug the two connectors that connect to the amp.
4. Remove the 4 screws(on the front panel side not the nuts on the board)
5. Look at the switching diode (labeled #1) directly beside the transistor cooling plate, if the board around this transistor is burnt there is a good chance that the diode is fried. If you do not trust your eye you can measure across the positive and negitave of the diode with your multi-meter (on the diode check setting) and you should read ~.565 and you should read infinity if you swap the leads. If the diode reads ~.667 and you can read this taken across any polarity the switching diode is fried.
6. If the diode is fried go to radio shack
7. Purchase a 1N914-1N4148 Switching Diode. Cost about $1.36.
8. Go home de-solder the fried diode.
9. Solder in the new Diode. ***Pay ATTENTION to put the new diode in the exact way the old one came out!!*** If you do not get the polarity correct the diode will not work properly and your unit will not power up. Also, it is a good idea to leave ~ 1/8" between the diode and the board, this will help disipate heat the cause of the problem to begin with.
10. Place power Board back on the backside of the front panel
11. Install 4 screws(on the front panel side not the nuts on the board)
12. Plug the board (Power Board) that is connected to the switch and plug the two connectors that connect to the amp.
13. Place the panel back onto the subwoofer and secure it with the screws. You can use a screw gun for this just make sure to turn you tourqe level back to ~3 otherwise you could strip out the screw and or the particle board.
14. Plug it in and your rolling.

I hope I am not to late and this works out for you. I just fixed mine tonight.

I have a lowrance LCX-17M that keeps blowing the internal fuse. I see a component on the circuit board that is fried, but I don't know what it is called. Does anyone have a schematic of a circuit board? ...


It could be a 33v zener diode that is in the circuit to protect it from high input voltages. If you can send a picture, I will verify. I had the same problem with a similar unit.

Got wet


Most likely he sprayed the screen, and the fluid dripped down onto the board where the pushbuttons are. The pushbuttons them became contaminated and shorted out inside. Usually, the damage done will not be reversed by drying the set out. He should not feel bad, though, because we see adults doing that all the time. The TV has not "had it", since it is quite easy to correct. The board should be cleaned and any defective pushbuttons replaced by a qualified tech.

Green color lost


First thing to check my friend is bad connections on the green CRT board, or cannections on the green crt and the socket. If there are no bad connections on the board, but to tell you the truth there most likely is, as I have found this problem many many times in the past, you could take off the green crt board and swap it with one of the other board from the other two crts and the picturew will not be right, but this will tell you if the problem is on the green board or the green driver circuit. if the green continues to go out on this setup, then I would tend to believe that the green CRT is intermittant. Good Luck

D20 Diode value on Motherboard.


Contact Dell support. Tell them that you were told by a tech (that has repaired many of these problems) that you believe you have a motherboard with leaky capacitors (do not mention the burnt out diode, just tell then it no longer boots). After much interaction with Dell technicians, it turns out that dell has extended the motherboard warranties of most of their PC's including laptops. I know of two people so fat that have had Dell warranty repairs done, even though the system was out of warranty. Once they hear "leaky capacitors" they will advise you that even though your unit is out of warranty, they will replace it. Hope that helps! Best regards

Ipod video conncted the wrong way.


I'm not 100% sure it has a fuse but it could have a protection diode, a fusible link or fusible resistor. Failing those it could be a burnt track on the printed circuit board. Then again you could've fried the whole shebang.
