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.

Re: Jvc EM65FTR 65 No Standby light DEAD
So this is what I need? That is for a vizio tv not a jvc though. I wonder if that would work?Comment

+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.Comment

Re: Jvc EM65FTR 65 No Standby light DEAD
Yeah RJ, I can't see that on my lil iPad. Next time I am going to buy the big one. Anyway... still same idea here, by checking the buck regulators that down convert the 19V to 5V STBY. If that buck converter is good, then its either the flash or the main CPU. You can try freezing the flash with a can of air upside down, then turn on the TV with the frozen flash IC. After that I would try backing the whole main board and see if that fixes it.Comment

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.Comment

Are you saying you ordered and received a new eeprom? Dot facing same direction? same direction of what? pin 1 is marked on both the ic and the boardLast edited by R_J; 07-21-2021, 09:14 PM.Comment

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.Comment

by mecha1166I am working on a QN750Q8FNBFXZA. Dead except the standby light. It blinks what appears to be 1 3 1 2. 1 long blink, pause, 3 short, pause, 1 long, pause, 2 short, pause, repeat. A service manual would be very helpful, or if anyone knows these error codes. Thanks!

by esqmoooHello everyone.
This is my development machine. I've been using it since two years and half without any problem except sometimes it wouldn't wake up from sleep.
Lately the issue became more frequent and powering it up would take few seconds to show the POST screen.
Then the computer refuses to power on at all. Now only the caps lock button flashes 7 times then stops. The charging light is always on whenever a power source is connected (battery or charger).
I tried long pressing on the power button, after several seconds it would go off then when the button is released... -
by wushumikeThe problem: When remote controller is press, the TV seems to wake from standby light goes off; but there is no backlight, image and sound. The relay did click on.
I have removed the power board to check. Using 2 x 10K resistor from 3.5V to PWR_ON AND DRV_ON, all the voltages is correct.
The main board has a red LED and is lited, but the optic link does not light up.
The Power board after sometime will start to blink x 5 interval.... I would assume this is to indicate DRV_On not working.
Any expert here came across the same problem? I... -
by shagsterHi, haven't been on the forum for a while. But I thought I'd ask here incase this has already been solved.
Anyway, I have this Panasonic TX-P50UT30B. It's completely dead, no red standby light, nothing. I took off the back and had a look at the fuses. All of them are intact. No shorts when testing the mosfets of the Power supply either.
And the capacitors look fine also.
I'm guessing it's a main board issue. But I don't really know tbh. Maybe a corrupt firmware flash, dunno. -
Hello everyone,
I got a Samsung The Frame 55 inch TV for free from uncle cause it is not turning on anymore. I am in the second year of training as an electrician so I have knowledge already but I am far away from to be a pro.
The TV has Standby but ist not turning on. A Friend of mine owns a 50 inch Frame TV so I checked the One Connect Box and the One Connect Cable there. Both are good and working normally. I have opened the TV case and measured some voltages on the Board.
What I already found is that the 12.8V are not an the connector to the main board connector to the power... - Loading...
