Re: Sharp Aquos blinking error help needed
Disconnect inverter connection - a shorted inverter can cause the 15V to drop out (will short 60V which runs off same trafo)

Re: Sharp Aquos blinking error help needed
The model number of the TV would be great help, as would pictures of the boards inside the set so we can understand the layout and configuration.Leave a comment:

Sharp Aquos blinking error help needed
Hi folks, I'm hoping someone can help.
I've got a Sharp Aquos LC32X20E in that has a flashing light error of LED x 2 OPC x 3
After speaking to sharp customer support (who weren't much help) the error was pointed towards either firmware upgrade or power supply issue.
I've done the firmware upgrade and also after testing the power board the error pointed at a Schottky diode which I've replaced. However the tv is still stuck with the blinking error code cycle. Before fitting the new diode I could force the tv on, However now I cannot.
Any help would be greatly appreciated

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 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... -
I have a Sharp Aquos LC-80LE757U that randomly made a loud popping noise when when watching TV one day. We found that the fuse blew and the thermistor. We ended up replacing the entire power supply board and have also replaced the TCON board. Now as soon as I plug the TV in it lights up and has the Sharp logo flashing on and off of the screen. If I unplug the ribbon cable from the TCON board to the main board I get the 2 long 5 short error code. Any ideas on where to go from here? We've tried resetting it but nothing has worked. If we plug it in and let it cycle through the flashing of the Sharp... -
Hello!
I'm a few days old into this TV screens repair universe so please bear with me.
Recently, and all of a sudden my 40” 4K Sharp Aquos LCD TV turned on with colors all smudged in some places on the screen that remain like that even without any kind of video source. I do have image but the colors are smudged/tinted/ washed out in patches as per defects. This to me looks similar to burn in but I’m shore this is not an OLED.
- I did the classic unplug and hold power button to discharge the caps but it didn't help.
- I did a factory reset as well... -
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
