Re: Sharp LC37D44U Blinking LED
I have been able to get sound after unplugging the unit and while unit is unplugged hold the volume up button and channel down buttons down and while depressing both buttons plug the unit in which should have put it in SERVICE MOD. but the picture is blank, I can see the backlight is on but no picture. -

Re: Sharp LC37D44U Blinking LED
Well I took the back off and I found everything to be looking good exept I noticed that 2 screws are missing on the power board, they have what looks to be grounding pads but no screws, doesn't look like there ever was so I don't know would that be it? I have heard some electronics can detect missing screws. Here are the pics, all caps look good.

Re: Sharp LC37D44U Blinking LED
The link above may point to the service manual; the service manual is also on Scribd.Originally posted by snipe
The failure codes are listed on pages 6-14 and 6-15. This appears to indicate failures in the 3.3V and UR6V supplies. The 3.3V supply is generated on the main board from the 5V supply, I didn't notice where the UR6V supply comes from.
The power supply schematic is not included. As a first step, look at the labels on the connectors of the power supply.

Re: Sharp LC37D44U Blinking LED
Well I have taken it in to be looked at and well it aint gonna be cheap, about $900.00 to repair, so I am working on getting Sharp to repair or replace the TV under warranty, so far it looks like they might.Comment

Re: Sharp LC37D44U Blinking LED
Well Sharp has offered me an LC40D68UT as a replacement @ $285.00. As much as I am not happy about it, it is cheaper then buying a new TV from a store. Oh the LCD screen on the old one has a short, that is what the repair shop has found, so I am trying to find someone that might have a dead TV that I can steal parts from, but I ain't holding my breathComment

Re: Sharp LC37D44U Blinking LED
Well I have kept that TV around all this time and I just came across an LC-32D44U that the sound quit on, so after doing some research I found that this TV uses the same Mainboard as the LC-37D44U and since the 37" has a toasted LCD panel I swapped the mainboard and boom, sound fixed on the 32", so I guess it paid off to keep it around all this time.Comment

Hello, on Sharp LC-40LE830E is everything OK. Working great. If I put the 230 V off and on again, it just blinking white standby LED. I can power on only via VOL- and CH+ and POWER button on TV. After that, I can power off and power on again without problem (by buttons or remote control) until the 230 V is connected. If i put the plug off and on again, just white standby LED blinking. TV needs three button starting again.. On the first look, the backlight looks great, no darker or lighter spots. Any idea what is wrong?07-21-2023, 09:05 AM -
Hi everyone,
I've got a Sharp LC-55N7000U. It has a standbuy LED when plugged in, but powering it on causes it to blink 1 LONG and 5 FAST. Theres no display and no backlight.
Nothing I checked has that blink pattern for Sharp TVs and there's only one multi-button on the TV itself so that service menu trick involving the input button doesn't work either. Its a post-Hisense buyout TV so that probably makes sense lol
I've tried disconnecting the panel sides from the TCON alternating sides, but no change in behaviour even when the whole TCON is disconnected,... -
Just picked up this sharp tv not too long ago and it started not wanting to start the other day, giving me the notorious 2 long-5 short blink pattern indicating a power issue. I was able to force start it a handful of times (once the tv has fired up it has no issue running for 5+ hours). But now as of yesterday, no matter what I try to do button combination wise, I just receive the same blinking code.
So I busted into it and have done the following:
-Removed the power board and inspected for any bad caps, burn spots etc. Do not see any instances of such ... -
Got this SHARP AQUOS LC-70LE836S for free - did some basic troubleshooting, and found manual - without detail schematics though. Comes from a meeting room with extremely few working hours.
Symptoms :
When connected to mains, the logo blinks continously, approx 6 times per 10 seconds.
A press on MENU as per the manual changes this to one short blink, one long and then repeats.
Only 5V ( Standby ) on PSU module present, no AC_DETECT, no 12V, no 13V, no PS_ON from mainboard.
As I see it mainboard has some kind of life, but does not... -
I am trying to repair an LG split AC indoor unit, which does not start and gives a CH05 error code.
This indicates an error in the communication between the outdoor and the indoor unit.
The outdoor unit is fine, so the problem is the indoor PCB.
The indoor unit is an LG PC09SQ NSJ (3SNM09JA2FA), and the PCB has the following type number: EAX35907219-1.2 (see photo1)
I changed optocouplers ICO1X & ICO2X and the NPN transistor S9013 which drives optocoupler ICO2X (see photo2), but this did not remedy the fault.
Does anybody have the schematics of this board,...02-01-2025, 12:55 PM
