Sharp LC-52LE830U one long one short blink troubleshooting - part 1

[royatavassoli]

Would you please explain alittle more about the LED drive portion of the USB in the sharp tv 52 le 830 . Perhaps in another video . Thank you ....

Did you ever fix the TV? Is there a part 2 ? I have the same problem. I got the flashing emblem to stop by pushing down volume, Chanell up, and power all at the same time. But never got back light to light. Never heard a click from relay on board. Don’t get the 400 vdc @ the 3 caps you show 170 vdc on. That’s what I get is 170 vdc. Is it safe to say it’s power supply because I don’t here a relay click if I have 5 vdc on PSON?

Hi, i have a sharp LC-52LE635U. The TV doesn't turn on but the LED at the bottom on the TV has a fast flash h and a slow flash

Do you have any links to or have a schematic for this power supply. I have one with a 1-1. Looks like the transformer has been getting pretty hot and also a few thin resistors have some browning on the board around them.

Any follow up? Did you wind up finding out what was the issue?

Hi, i have a sharp LC-60LE650U that stopped working when my house got struck by lightning a couple weeks ago. I tested the power board using your tips and determined that the board was bad. I got a replacement power board from eBay and installed it. I checked all the voltage again and everything seems to be the same as yours except that when i press the power button, i get 7.5V instead of 12V on pin 1. The TV still doesn't turn on but the LED at the bottom on the TV has a fast flash and a slow flash. 

I should mentioned that i didn't check the voltage output to the LEDs. Not sure what these should be reading. Im assuming that the power board i bought is oK since i get some lights but i get worried with the 7.5V. Could that be the main board?

Please let me know what you think. I tried the reset sequence and i still don't get anything.

you need to jump stby and dimmer with 5v in order to activate voltage to the panel.

[lordklark]

friend, I have the same board, I have the voltages in the primary board, but in the secondary I have not even the 5 volts could you give me a hand? Where can I start from? Thank you and hugs from Brazil.

Ok I have a 55 inch sharp lc55ub30u when I plug it in it blinks on the Sarp logo on screen then off .. do you think I should just change out the power supply board?

[waltersantiago]

i have the same exact TV that is complete dead. Change the main board and now it power on and off thru the remote only, but there is no sound, image.also, it doesn't power on nor respond manually. could did be my problem? i don't want to keep trowing monies at something not worth to repair.

Hi good day I have this same error code. Is it safe to say it’s definitely the power supply?

[mysterypostman]

I got the same problem with same model. Watching this wasted my time. Thanks anyways.

[jeff-yrwi]

Waste of time!! You never determined or told what the issue is

[bikerboy]

I cant understand this guy, whats up with his voice?

[TungstenCarbideTempe]

2) change the title of your clip

There's literally no troubleshooting in the video. Just continuous incoherent babbling.
