I have a Sharp LC-60LE650U that shuts on and off with only Sharp logo displaying before it goes off then repeats. When the tv is powered on the standby light is blinks once then goes off for a count of 2 then then repeats same. I could use a schematic for this model if available.
Thank you to the guys at HEGE supporting Badcaps [ HEGE ] [ HEGE DEX Chart ]

Re: Sharp LC-60LE650U
More than likely a probem with eeprom/spi/nand on the mainboard, easiest fix is a replacement mainboard if that is the problem.Last edited by nomoresonys; 10-18-2020, 09:38 AM.

Re: Sharp LC-60LE650U
1) There is not much info in the service manual. https://www.manualslib.com/manual/11...-60le650u.html
2) I have error codes for 640 so it may be closed enough, see attached PDF. ou should re-verify the blink code again Example of error code: https://www.youtube.com/watch?v=jHjBjIaQzXc
3) Show us good clear pictures of the whole backside of the TV showing all the boards, the good clear straight shots of the whole power supply board.
4) What Voltage testing have you done on the power supply connector that goes to the main board?Never stop learning
