70c7500u
Hi guys,
I have a sharp LC-70C7500U which was giving me 2 slow blinks and 5 fast blinks . I have disconnected the tcon cables and when I disconnect the right side the tv comes on with one side working and the other side just a white screen. Do you think it's a bad panel or can it be the tcon ? Thank you ..Last edited by Samantha143; 10-26-2017, 12:36 PM. -
Re: Board capacitors
So you wouldn't recommend removing them from the old board even if they are the same ??Leave a comment:

Board capacitors
Hey guys this might be a stupid question but I want to know if it's even possible before attempting... I have two exact tv boards they both are not working. One has two bad popped capacitors and I don't know what's wrong with the other one. My question is can I cut at the curve ( see pictures) the two capacitors that are good on one board and cut out the ones that are bad leaving the two legs and Solder it to make them "like new" capacitors. I know it might sound confusing it's just if I remove the soldered legs won't be long enough so I am trying I use the good capacitors into the old...Last edited by Samantha143; 07-09-2017, 05:43 PM. -

Re: Sharp LC-70LE745U
Also here are some pictures with voltages that I got from the wiring and to the leds themselves. Also a picture of how the wiring splits. But when I measure the wiring coming from the PS I get 83 from all positives....Leave a comment:

Re: Sharp LC-70LE745U
OK here is an update. I tested each LED individually and they were giving me 2.8 volts each. Tested the strips with the LED tester and it read 92.1 volts to power on. I measured the volts coming out of the power both PB the old and new and they both are giving me 83 volts.Leave a comment:

Re: Sharp LC-70LE745U
We have the led removed from the back to the front with the boards connected and the logo still turns on the same way but the LED do not light up at all not even a quick flash. We even tested the LED cable that connects to the power board and it works.Leave a comment:

Sharp LC-70LE745U
Hi guys I am breaking my head here and not sure what to do next.
We have a sharp LC-70LE745U that was originally giving us a blinking error code 2 long 3 short and it pointed to be a main board error. We replaced the main board and the error code went away and he front logo turns on regular. Now we have no backlight. We did the flashlight test and there is a faint image. We opened it up and tested each LED strip and they all turn on , we replaced the power board and it does the same thing. Not sure what else to do, any ideas ? Maybe a reset ? Not sure -

Re: LC-60LE810UN Sharp
LED tester. I can test indivial LEDs or the whole strip. No i have not tried that. I assumed that testing the LED strips it would show me if one was bad or good. Thats how i found the one strip bad.Leave a comment:

I tried reseting the TV by holding input and vol - on panel it self and nothing. Still same error message. What... -
