sharp aquos LC-80LE632U led tv lamp error

[Inverted]

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

service manual shows input vol- at the same time in plug in TV but when I try to do that I get the one flash two flash sequence I can't get it into service mode. the only way to get this set to turn on is to hold down the volume down channel up button at the same time but that wont allow going to the service menu

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.

Hello Sacosta
This is a different model so you would be better off starting a new thread.

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

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.

The mainboard must generate only one signal the power supply gives it if backlight is in error. All other errors are generated from mainboard. Off the error pin if it goes high it generates a power supply fault codetwo quick flashes 5 slow flashes. The error pin stays low all tje time. Without or with the backlights working I believe the mainboard monitors this by the balancing of the data and clock signals generated by the backlight driver. The pins are called adl and acl

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.

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.

"Do you know if the burnt out LEDs could cause this problem and are they replaceable?" Yes, the LED driver will go into protection shutdown mode.

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

hey all well I picked up this 80 inch Sharp Aquos and I'm getting one short flash and 1 long flash. according to the error sheet it appears to be a lamp error. Now this is an LED TV and a lamp air would be generated by possibly a bad LED backlight? This is the biggest TV I have ever worked. Has anyone else encountered lamp errors with the Sharp Aquos line?

by the way nothing lights up on the screen upon powering it up it immediately goes in the lamp error flash sequence

I am a little to the game here and not sure if you'll get my message. Perhaps it will send it to your email. I've got a Sharp Aquos LC-60LE640U and I have the one and one flash. I replaced the power supply/inverter board, but it didn't fix it. I did try to do the reset and the light stayed on for about 5 seconds and went out. Then I tried what you said, to press the volume up, channel down and it does bring the screen up and is operating. Once you pull the power, it won't come on. I noted that before the set went out a few weeks ago, the lower part of the screen appeared to be missing some of the LEDs. There was dark patch at the corner on the bottom. I read through the blogs and if I understand what you're saying, an imbalance in voltage can cause the power supply to shutdown? Do you know if the burnt out LEDs could cause this problem and are they replaceable?

Sounds like bad led strips to me.

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

Good Evening! I did not want to hijack a thread but seems I can not post a new one and my issue is kind of the same as the original post. I have a Sharp LC-52LE830U. It turns on but throws the lamp error. The TV when powered on will come on for about 2 seconds then shut off. After resetting the lamp the TV will turn on but the backlights go off after the 2 seconds but the screen stays on. I can turn all the lights off in the room and shine a flashlight on the screen and see the screen and service menu and all just no backlight. I replaced the backlight inverter board and still have the same issue. Any suggestions? Thanks in advance.

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

Hi. So, the TV finally came on and I was able to access the factory menu. Service model. By keying menu 3481 on the remote one after another. Not holding menu while keying the numbers as the manual seems to suggest. Problem is, there is no lamp error reset option anywhere in the factory menus. Should I just restore back to Factory a Reset?

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

Thanks for helping. While not for my TV that PDF offered something. The only service mode code that did anything was for the CSM. It turned the red front LED green. But alas, since I have no image even if I was in a service mode I can't see anything to find and reset the codes. I fear this is a lost cause. Which is frustrating as for a while on cold mornings the TV started. Then, now armed with what appear to be the correct codes, I would be able to access and reset. So, what I need now is a way to bring the screen back to life. It stubbornly remains black. The back lights all work but no input image, no blue screen. I miss the blue screen.

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

Dont know if this is something to look at ?

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

Hmmm... A small sign of life. The service manual says to enter service mode you hold menu and key in 3481. I assumed all on the remote. But menu button on the TV and numbers on the remote turned the red led to green so I think maybe it did enter service mode. But without an image on the screen there's not a lot I can do with it. Hopefully a cold start will work to light up the screen in the morning and then I'll enter service mode. Again hopefully.

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

Hi. Was that for my 32" Sharp? I did try it as it's yet another suggestion as to how to get into service mode. Alas it did not work. The red LED on the front is unmoved and TV appears to not recognize any remote command. The led will turn green if I use the power button on the TV. Remote batteries are fine. When, on the rare cold occasion the TV works it recognizes the remote and all inputs and instructions. Vexing issue really. Just need to reset those lamp error codes or jump the component on the led board if you happen to know which it is. Thanks.
