Dead JVC AV3589S 35" TV
Got a dead JVC 35" (or maybe 36") TV. Model AV3589S I hear the relay click when power button is pressed. No LED's light up on the front and no high voltage felt on screen. Haven't opened it up yet to check B+ or other supply voltages (damn this thing is heavy). Any repair tips would be appreciated. .. |

Step two: learn how to have it go to a search site like google. Step three: learn how to enter usefull search terms like "sci.electronics.repair faq" step four: visit http://www.repairfaq.org/REPAIR/ step five: look for stuff on repairing tv sets like: http://repairfaq.ece.drexel.edu/sam/tvfaq.htm Pay attention to the section about high voltages if you want to avoid a painfull mistake. |

I have many years of experience working on TVs and computer monitors. You've told me absolutely NOTHING. Now what I have here is a dead JVC TV with no service manual or schematics. I'm sure I could get in it and familiarize myself, and eventually fix it, but in order to maybe save some time and troubleshooting, I thought maybe someone had encountered this problem before. Thanks for nothing. |
ESR the caps in the stand-by power supply and regulator circuit. Check the
obvious things in the deflection circuits. Good Luck. "Slim" wrote in message ...

Doing a google search, I found three references to high esr capacitors
in the power supply taking out the regulator ic. Start there. |
