I replaced 2 strips in this unit and was able to get it to turn on by pressing v- channel up and then power button.This unit has touch type controls.I went into menu each one and done a reset but when i unplug unit im back to powering up with v-,channel up and power.The lamp error isnt resetting.Is there special method for these non conventional control button units or is reset procedure done from remote in menu setup?

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.

Hello Sharp TV experts
Our Sharp LC-80LE642U displays one short one long flash error code which is a backlight error. I went into service mode and there were 8 lamp error counts recorded. I reset the count to 0 and did a reset. The last monitor error cause was 16 B00014639:12. 16 is the code for backlight error. I tried to power the tv up but went back into error mode.
> I checked voltages on the power supply board and they all check out .. including 3.28 volts at the error pin.
> There is power to the cpu and T-CONN and no faults found there. The cpu has a flashing...01-24-2025, 11:51 PM -
Hi,
My lamp has going to end its life by counter, but lamp phisically seems to be in good condition.
As far as I get known there is atmel 24c64 eeprom used to save lamp life counter. Here is dump of it but unfortunately there is no counter in plain text.
Maybe someone has clear dump of it or has tips how to set counter value.
best regards... -

how to reset lamp hours on acer x117h projector after replace lamp. -
Hello everyone, I just got my hands on a Sharp lc 80le632u TV that initially had the 1 short, 1 long blink sequence. That indicates a lamp error, however if I follow the isntructions to reset the error counter, the TV starts correctly: no missing LEDs everything lods just fine.
I went through the process to get to the diagnostic screen, and got this ( attached).
Since all LEDs are working correctly, and the TV seems to load fine after reset, that tells me that the power board and the LED strips are working correctly. Could this be a main board issue?
Any...
