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... -
Hello, I'm new to this forum. I like to tinker with Sony electronics, I have been lucky trouble shooting sony stuff, But I can't find much info on this Sharp TV.
The problem; plug to power>white led power indicator light is on>it turns on to the red Sharp logo>
then the android logo is displayed, lit fine then the android logo brightness varies, then lit normal, then the tv restarts and does the same startup logos over and over for 5 times then it turns off and the power indicator light flashes the trouble code 3 long blinks plus 3 short blinks .

hi, I have a sharp tv model LC-40LE814E with DPS-126CP-1 A power supply.
the tv initially turned on, displayed the image for 10 seconds and then turned off. so in a loop until the power was cut off.
reading the classic optocoupler problem I changed the mounted cosmos with SHARP PC817 recovered from other boards.
now the TV turns on for 1-2 seconds and turns off giving 2 flashes in the front LED.
to avoid banging too much I preferred to take an identical tested and working card (or so the supplier says)

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...
