    Sharp LC-70LE650U Will not turn on

    Hey Gang,
    I bought this one second hand but I am now thinking I got a dud. I've got an error code of 2 slow then 5 fast blinking lights on the stand by. I've checked to see if the main board is getting 5 volts and that checks out. I unplugged the tcon board and it now powers up. However if this is the case i've heard I may have a bad panel and not a bad tcon board? Any help in troubleshooting would be greatly appreciated.
    Cheers.

          Yeah I did check those but they didn't seem to line up with my issue. However I was able to determine that it was a panel fault. Thanks for the response.

                  BUT... what do you mean "panel fault"... a lot of these have panel faults ... BUT they can be saved by removing the drivers on the faulty side IF that is the type of panel fault you have... hence the question.

                      Driving a Sharp TCON/panel with a universal main board
                      by advant
                      This thread is about trying to get an Universal Main Board to work with a Sharp TCON and panel.

                      I have a Sharp LC-46D85UN TV that has had a main board issue. Since this model is from 2009, I am not able to find an exact replacement of the main board. Instead, I decided to see if I can future proof this tv by getting a Universal Main Board (T53U21.2) from China to work with the Sharp TCON (CPWBX4291TPZA) and panel. The universal main board supports a 8 bit dual channel LVDS interface whereas the TCON requires a 10 bit dual channel LVDS input. I have modded the LVDS connector to match...

                      Sharp LC-52E77UN TCON activation WITHOUT motherboard. I2C reverse engineering help?
                      by moltensolderlabs
                      Hi everyone. [Sorry for the long, detailed post in advance].

                      I have a Sharp LC-52E77UN which randomly shuts down--could be within 15 minutes, could be 40 minutes, over 1 hour, it's unpredictable. From reading the service manual, I was able to get into service mode (where the K is displayed), and found the following error flag toggled: "04 Initial Communication Error 4 -- Error reason: To the communication setting reception," which, from contacting an eBay TV repair store, I was told is caused NOT by a bad TCON (which was my first guess), but rather the motherboard....

                      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!!...

                      TCL 50S535 bad tcon or panel issue?
                      by x_orange90_x
                      Just bought this for 10 bucks yesterday hoping to fix it. The guy said water dropped inside from a dehumidifier hose and it started showing black and white vertical bars then went blank. When I got it home and turned it on it came on fine and displayed correctly but I was noticing faint vertical bars in the image. After a little bit I turned it off and back on and it was a black screen again. I opened it up to check for water damage and corrosion but didn't find anything of the sort. I cleaned the ribbons anyway and reconnected them but still got a blank screen. If I disconnect the right side...
