    Re: sharp aquos LC-80LE632U led tv lamp error

    Your TV is a completely different ballgame the 80 inch uses LEDs that are backlit your TV uses edge lit so if you have one LED go out in your string you're going to have an array of LEDs in that same area go out causing a black patch.
    Did I leave the soldering iron on?

        I have sharp LC-80LE632U tv I have no picture at all. was watching and the screen went blank. I tried a factory reset and flash light to see if the screen was on but it wasn't. I not sure if the back light is bad. The service manuel they show the componet positions and interconnections. The light is white and steady flashing when you turn the power on with the remote it goes out like power came on but the screen is still blank. Is there anything else I can do before I open this beast up. I would much appreciate any type of input.

        Thank You.

          Dont know where to start tv won't power up at all. Tried reset with the input and volume down holding and pluged tv back in. No luck, anyone know anything about where to start to test to find the problem. I hate to open this beast up unless I really have to. The power light is white and flashing steady. When you power up on the remote it stays on steady. The screen is still blank, anyone have any idea's. The service manuel doen't tell you anything it just tells you how to take it apart and the layout of all the boards that interface with each other.

            freakaftr8, I don't think you posted how you repaired your TV in the end?

                  Hello Sacosta
                  This is a different model so you would be better off starting a new thread.
                  Willing to help but I'm no expert.

                      Have you hooked up different inputs and it happens on any of those inputs?
                      Don't buy those $10 PSU "specials". They fail, and they have taken whole computers with them.

                        What was the fix for this? I am having this exact issue and the fix was never posted. I am having these EXACT same issues with a Sharp LC-70LE374U. If I hold the vol+ and channel- when I start the tv, the tv works great.

                          Sharp LC-60LE810UN Lamp Error
                          by Yanleb
                          Hi all,

                          I have this Sharp LC-60LE810UN that stays off and blinks a Lamp Error (1 long flash followed by a short flash, in a loop).

                          I already confirmed that the first backlight strip has an open LED using a LED strip tester. The other 3 LED strips are fine.

                          Before tearing the LCD panel apart, I want to make sure that the rest of the TV set is good. I've tested the power-supply/LED inverter board by sending 5 volt to PS-ON, to PNL-POW (that commands power the T-CON board only), OFL and STB pins. The power-supply is good.

                          I've tried all the key...

                          by michalk3777@gmail.com
                          Hello, looking for a list of error codes for this TV. made in 2020, its manufactured by Hisense under Sharp brand. No clicks, black screen, no sound, power light is on solid. When I press power, it blinks 5 normal blinks and 1 short. and nothing happens.
                          Anybody has a list of error codes that might apply to this TV? I have not opened it yet.
                          Regards,...

                          Sharp Aquos LC-70C6400U Half Screen Dark
                          by scubacamper
                          I found another post on this site the other day which has been very helpful in troubleshooting this issue I am having with my tv. The left half of the screen is dark, and the other half is VERY slow to generate it's image - and it only generates part of its image at that.
                          Based on this yt video, I have narrowed it down to an issue (short?) on the left side of the display, somewhere in the system of ribbon cables.
                          when I remove the bezel and the rear cover, I can get the image to display correctly by manipulating the ribbon cables on the left side which connects the left lower display...

                          Sharp LC-60LE810UN Lamp error
                          by Eric D.
                          Hello everyone!
                          I just acquired a Sharp Aquos for free.
                          When I plug it in, it will try to power on, but it fails.
                          The "error code" is 1 long flash, then 1 short flash, which suggests it is a lamp error code, according to the manuals.
                          I did a bit of research and did what I found could be the possible issues;
                          I removed the back panel, checked for continuity on both fuses where the power cable connects, and I get somewhere around 0.05. That should be good.
                          I also tested the leads going into the psu board from the wall connector; I get 120V.
                          I disconnected...
