Hi all, I have a very nice 65 jvc tv with good ole component inputs. Its dead as it gets no power, no standby light. I know these tv's have issues with eeproms. Anyways here's some pics I cant find a eeprom for my board # on shopjimmy, kinda weird.
Thank you to the guys at HEGE supporting Badcaps [ HEGE ] [ HEGE DEX Chart ]

Re: Jvc EM65FTR 65 No Standby light DEAD
Shopjimmy has the correct eeprom for $15.00. If you have any freeze spray, Unplug the tv, Spray (freeze) the ic, wait 10~20 seconds and plug in the tv and see if it will turn on. Some times this trick will work indicating the eeprom is at fault and allows the tv to be checked. If this does not work, it could still be a bad eeprom.

+19v supplies UP1? which outputs +5VSB. I will find the correct ic numbers, I believe they are up18 & up1Last edited by R_J; 07-12-2021, 08:05 PM.

Re: Jvc EM65FTR 65 No Standby light DEAD
Not to beat a dead horse, but almost without fail the 5vdc reference/stand by voltage is produced on the power supply board. I’m not familiar with your set but in general, that’s pretty much standard throughout the industry. There maybe a 19v-5.0v regulator on the main board but its possible that 5v is for another purpose. Good luck.

Re: Jvc EM65FTR 65 No Standby light DEAD
If I would have known earlier that this board has an MSD main IC... that's your problem. 9 times out of 10 when I had a main board with the MSD main IC it was bad, not the eeprom.
Looks like there is some questionable (re)soldering work around the MSD IC.
