Hi everyone,
I've got a Sharp LC-55N7000U. It has a standbuy LED when plugged in, but powering it on causes it to blink 1 LONG and 5 FAST. Theres no display and no backlight.
Nothing I checked has that blink pattern for Sharp TVs and there's only one multi-button on the TV itself so that service menu trick involving the input button doesn't work either. Its a post-Hisense buyout TV so that probably makes sense lol
I've tried disconnecting the panel sides from the TCON alternating sides, but no change in behaviour even when the whole TCON is disconnected,...

OK so I tested the CN/OFF pin as well and it comes to 4.7
And it seems it now takes multiple power button pushes to get the red standby light to GoTo the white turning on light and that's when I can get the 12v on the 12v pins...Leave a comment:

Re: JVC JLC37BC3002 Glitching out and crashing to standby
The ON/OFF maintained a voltage of 3.29 after pushing the power button and the 12v pins maintained 12v this time even after going back to stand by
All though I repeated this and while the ON/OFF was the same this time the 12v pins fluctuated between 5 and 0...Leave a comment:

JVC JLC37BC3002 Glitching out and crashing to standby
Hey everyone,
I got a jvc jlc37bc3002 from a friend, and i can turn it on to the logo but when it does one of 2 things happen either the logo comes on and turns off again or the logo comes on and it will crash in a spectacle of graphical glitches and then turns off.
Each time it turns off it goes back to the stand-by light, but won't turn back on until i unplug and plug it back in again.
I've got the Voltage Regulator readings:
UP3: All i can read on it is 1117, line 1 is something like DH11D or something
1: .258
2: 1.524... -

Hey all, names jared.
Looked like this was a great forum to join and learn how to actually fix broken main and power boards instead of just defaulting to replace them
