01-12-2008 | Vintage Pioneer Amplier SA-500 Repair HELP!!! | I have a vintage SA-500 pioneer amplifier that was not outputting anything out of the left channel. I opened it up and saw the fuse was blown for the left channel. i replaced the fuse, switched it on, and it blew immediately. After this, I de-soldered 1 |

01-12-2008 | | The power to the inverter is a monitored 5 volts and the supply is usually either 12 or 24 volts. If the supply is missing the 5 volts drops down. |
01-12-2008 | | if you have a multimeter i would suggest you check any other transistors around the one you replaced for shorts |
01-12-2008 | | I can test the other transistors for short. I think I did that, but I'll try again. There are 2 transistors per channel. I replaced both in the left channel, and experienced the blown fuse problem. Would anything else nearby affect that part of the circu |
01-12-2008 | Convergence chips can stk392-020,s replace STK392-040,s | Hi, I'm new here and have a question. I have 2 new STK392-020 and a panasonic With STK392-040,s in it. I've determined that the the problem is definately on the convergence board by removing the output plugs. (the TV now works) Now the STK392-040,s are a |

01-12-2008 | stk392-020 and stk392-040 | hi, I know an stk392-040 will replace an stk392-020 but is it just an upgrade and the stk 392-020 will also work??? |
01-12-2008 | replacement screen for a pionreer model pdp502mx | any one knows where i can get a screen or buy one of these tv for parts |
02-12-2008 | | I believe the screen is part of the panel. |
02-12-2008 | | STK392-020 is a lower wattage. Usually 040's replace 020's. They may not work or may fry. |

02-12-2008 | | Thanks. I'll take a closer look at that schematic and try testing the components and compare them to the good channel as a reference. Any other advice. So far this has been helpful. |
02-12-2008 | | May not be a bad idea to change or at least test the electrolytic capacitors(if you have a tester?). The amp at this age will probably need them---After you have found and corrected the problem.
Generally they do not cause a short or a catastrophic pro |

02-12-2008 | Gps u/s | I posted areply but my ISP cut me off(3 times!!!) They are just dirty @#$#@@% bassids!!!. If this gets thru, get a circuit, learn how to test electronic components- start at power supply. If all else fails, I am sure that Minnie or vtech would be happy t |
02-12-2008 | | When troubleshooting an amplifier with a such problem, it is a good idea to replace the fuses by suitable current limiting resistors during testing. Then, if anything goes wrong, there is no risk of a temporary current surge that may cause unnecessary da |
