    Sharp 70" LC-70TQ15U Won't turn on.

    Hello,

    I'm trouble shooting this unit and could use some help. Here is what I have found so far:

    *Standby light is on.
    *Back panel removed.
    *No signs of heat or damage on any boards or components.
    *A tiny led on main board is lit when plugged in.

    Pressing power button does nothing. No clicks, nothing on screen or any sign of life.

    Any advice on what I could do from this point is greatly appreciated.

    Thanks in advance,

    Todd

      Interesting because I have the same TV in the garage that I put in there because it did the exact same thing as yours. Must be something about this model.

      I hope we can find a fix.

          Hope we get a response. I'm not charging for the repair. Working on this TV for a friend

              search on the sharp 70 ... lots of posts on how to check and potentially "save" the set.

                      If you can you supply photo's of the rear of the set showing circuit boards and interconnections and also power supply voltage readings you have taken, perhaps someone on this forum could assist.
                      Willing to help but I'm no expert.

                              by thetonywarren
                              Sharp TV/Display, wont turn on. Brand new, used for maybe 30 minutes. Possibly heard pop then set went dead. I took a look at the boards, no visual damage to boards. The led power indicator is ON, remote will not turn on. I verified that backlights do come on when powered with separate power supply/LED tester. I also...

                              Sharp lc-55p6000u won't turn on
                              by JunkmanJimbo
                              Sharp lc-55p6000u won't turn on. The standby light is on but nothing happens when the power button on the tv or remote is pushed. I'm thinking this is a main board issue but they are expensive. I was wondering if anybody could tell me how to repair the main board I have. There is a repair service on Ebay but they're also expensive. Since there's a repair service for this main board I was hoping somebody could help me with the repair. The main board part number is 221999. Thanks!!...

                              Hello, i have some issues with my laptop Lenovo Y700-17ISK (motherboard BY511 NM-A541), it started when i turn on the laptop, but the lcd wont turn on, i then connected it via hdmi to tv and screen was ok. So i thought maybe lcd stripe is faulty, i removed the bottom cover, disconnected main battery, reset the cmos by disconnecting battery for 1 min, then slighty move the lcd stripe. Conncted power supply and tuned on my laptop, the lcd turn on, it started to load os, then it turn off, after a second it turn on, then after like 3 seconds turn off again, and so on. Removed power supply, waited...

                              SHARP LC-40LE814E does not turn on 2 flashes
                              by Egidio85
                              hi, I have a sharp tv model LC-40LE814E with DPS-126CP-1 A power supply.

                              the tv initially turned on, displayed the image for 10 seconds and then turned off. so in a loop until the power was cut off.

                              reading the classic optocoupler problem I changed the mounted cosmos with SHARP PC817 recovered from other boards.

                              now the TV turns on for 1-2 seconds and turns off giving 2 flashes in the front LED.



                              to avoid banging too much I preferred to take an identical tested and working card (or so the supplier says)

                              SHARP LC-70UC30U starts up with RESET then turn off and blink 1 LONG 1 SHORT
                              by Mitike
                              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....
