When the TV is powered, there is video for 20 seconds and then the LED backlights turn off. I have looked all over to find a drawing and schematic for the drivers but alas I haven't found anything that shows thre circuit. When it works, WOW! The white/black contrast is amazing.

The 25V from the power supply is there all the time the unit is on. There are 2 lines from the edge connector, ORG & YEL which seem to be control/sense for ADC. If only I had a schematic for the LED board, actual circuit on Power Supply-ADC and drivers. Anyway.....they both seem to be low at all times. Aha! Maybe that is the reason for the failure. It is my estimation that it could be on either board, at this point. I am prepared to purchase whichever board it might be. Please advise.

I need a copy of instructions for setting and operating this clock! Could you E-mail this information to me?

Thanks

We bought a Model LC75N8003U 75 inch tv from Best Buy approximately 7 months ago and to say that your customer service is less than stellar is absolutely gross understatement! Approximately two weeks ago, our tv went dark and nothing worked for the exception of a blinking red light. We called for service and were told that service people would be there today (08-05-19) then we are told that there was no paperwork or calls pertaining to our request for service. At which point they issued a service number (H934267) and were advised that service people would not be there until Friday August 9th. I know that we are just another number to you all, but we spent hard earned money on your product and to be treated this way by your company is an absolute shame. Needless to say I am extremely upset and will never EVER buy another Sharp product! But I am asking that you all to at least have the common courtesy to respond to my inquiry!
