Re: Sharp Aquos LC-32XL8E blinking lights
You will get a lot more help if you upload good clear pictures of the whole backside of the TV showing how all the boards are connected together, and tell us the history of the TV and what kind of testing you have done so far. It is not easy to do long distant troubleshooting when we do not have the TV in front of us to look at.Never stop learning

Hello,
I have a Lenovo here that does not want to power on. The motherboard appears to be clean, no sign of corrosion or obvious fried components. When plugged in, I see 3 blinking lights and then off. It would cycle the 3 blinking lights every 10 seconds or so as long as I have the adapter plugged in. Amp meter shows 20 volts, 0.224 amps, no fan spin, red light indicator near the charge port.
Thermal camera shows a section of the motherboard that is warmer than the rest. It is near the connector labels JRTC1 (CMOS battery). Diode measurement to ground for pin 1 = OL,... -
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 2019 75" x950g, and while playing a movie, the screen suddenly went dark in a weird way, where it faded towards one corner into being fully black. Now the TV turns on, and the backlight comes on, but there is nothing displayed except black. Sound still comes through the TV speakers, and i have tried doing a hard reset using the volume - and power buttons while plugging the display back in, but it did not fix it. I can confirm that pressing buttons on my remote is still doing "something" because I'm hearing sound still, even though the screen is black.

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...
