Re: Sharp Aquos LC-70LE650U blink code meanings
Glad you got it working!Don't buy those $10 PSU "specials". They fail, and they have taken whole computers with them.
My computer doubles as a space heater.

Re: Sharp Aquos LC-70LE650U blink code meanings
I have one with a blink code of one long and three short led bleeps. that is not listed in the service manual I downloaded on pages 6.1-6.3. all the codes start with one or more long lights followed by short ones. I have One Short then Three longer lights of led code.
What is the problem of one long and three short led light code? No schematic or pinout for jumping the power supply on. not listed in manual either.
Any help on jumpering on the P.S. is appreciated. I don't want to buy a Main board if I have a P.S. problem also. ThanksComment

Re: Sharp Aquos LC-70LE650U blink code meanings
Have the Sharp LC-60LE832U; 1 long and 1 short blink. Vol- and Cha+ does not create any results? Holding the power button does not do anything either. Any suggestions?
ThanksComment

Start a new thread showing the make and model number, you must also provide good clear pictures of the whole back side of the TV showing all the boards, then good clear straight shot of each boards so you will get more helps from us.
What Voltages testing have you done so far? The more details the better. History of the TV?Never stop learning

Re: Sharp Aquos LC-70LE650U blink code meanings
Okay, will get pics and post. No voltage checks yet, will need to get a good voltmeter. Has worked flawlessly since new (4 or 5 years; best guess), went to turn it on yesterday and noticed the long blink/quick blink of the power indicator.
Tried all of the tips in related threads and never get any response from the TV.
Will add that there was a brown out earlier that morning and the power dim several times in a row. TV was not on and nothing else seemed to show any problems. Did not have to reset clocks etc.
Thanks

Re: Sharp Aquos LC-70LE650U blink code meanings
Found this thread looking for the answer before i began my 2 long 3 short blink error. the 3.3V comes from IC 9606 on the main board. I had about 1.4v on the output but that wasnt my issue. Sharps schematics are less than helpful so manually tracing everything back, i found my 2.3V regulator to be bad. its IC 9601. This 2.3V buck regulator feeds a switching IC on the back of the board at Q9604. Without the 2.3V supply it will never switch this transistor and pull pin 2 LOW on IC9606(your 3.3V buck regulator) Start by checking pin 2 on this IC and if it is above .5v then go check out IC 9601 and see if 2.3V is missing from there. its late, im sorry if some of this is incoherent but there is your solution, those ICs. also i replaced IC9605 because it had a bit of resistance on pins 1 and 2(about 2kohms) so did this for good measure.Attached FilesComment

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... -
Hi community,
I will describe my problem with a TV in those short following terms to be the most precise :
What i have :
Sharp Aquos LC-60LE635E
power board DPS-162KP-1
main logic board QPWBXF733WJN2
symptoms :
white led light logo at startup,
after 2 minutes, blinking 3 times a row, repeating
no backlight (and apparently no picture, checked panel with flashlight)
no startup sound
powerboard investigations :
1-2 PNL : 0v
3-4 GND
5-6-7-8 UR : 13.15v
9-10-11-12... -
Can anyone help me diagnose this? Almost not worth bothering with, but it has 'sentimental value' for the owner. I'm no TV technician, but dabble a bit.
The TV has standby power but no reaction at all to switching on or reboot steps, No flashing lights or response to menu button. All voltages on the power board are correct apart from missing voltage on pin 12 of CN7003.
There is 13 v on U7053 but no 3v signal to switch it on. I don't really understand whether the 3v should come from U7401 in the standby control area, or (as suggested elsewhere) from the mainboard via pin 12....
