Re: Vizio E65-E3 Dead after backlight replacement
so I did all what mentioned above and still did not turned on the LEDs however I did try to put an E80-E3 main board and it starts right up and LEDs on
(the picture is shifted and stuff like that but I guess its because the E80 is programmed for a T-CON with 4 output)
anyway the red wires from the mother board to the LEDs is all having the right output voltage but no GND (I assume its a low side switch circuit) while I was testing the LED switch transistors for GND continuity I placed the multimeter's...Leave a comment:

Re: SHARP LC-70UC30U starts up with RESET then turn off and blink 1 LONG 1 SHORT
UPDATE:
So I tried to run some tests on the T-con
It has 4 ribbon cables connected to the LCD panel I've disconnected those in every permutation but the set always ended up turns itself off and blink 1 long and 1 short on the stand by LED
The display was "rotating" in 2 states Black/White/"Actual picture" depend on what combination of the ribbons were connected/disconnected. But again after the SHARP and the android logo still turned off.

I cant make it stay on long enough to bring up any kind of menu... as I originally wrote the set turn itself off after the SHARP logo. That's my main issue ... picture seems good LED seems good even after disassembly and still 1 long 1 short and it means hardware error
My tester is able to put out 350 V and 160 mA BTW...Leave a comment:

I have no history .. found the set on FB Market as a fixer upper for 40$ and I thought let's give it a try since the TV originally a high end model...Leave a comment:

SHARP LC-70UC30U starts up with RESET then turn off and blink 1 LONG 1 SHORT
Hello guys,
I have SHARP LC-70UC30U which won't turn on and the stand by LED blinks the 1 LONG 1 SHORT error
According to other sharp SM-s it is lamp error (I can't find SM for this model)
And yes I checked other blink error threads on the forum about other Sharp models and still can't make it work.
If I unplug the set and hold the POWER and INPUT buttons while I'm plug it back the set fires up and shows sharp logo and after that the Android logo and turn itself off again and starts the blinking and wont turn on again except if I do the RESET procedure again....Last edited by Mitike; 02-16-2020, 08:14 PM. -
