Have TV Questions? Ask a TV Technician
Hi, my name is ***** ***** I will do my best to help you today. To make sure I don’t miss anything, please give me a minute to review your question.
- What are the original symptoms of TV that prompted you to replace all those boards?- Is there any change in TV symptoms after boards replacement?
OK, did you get identical replacement boards having same part numbers?
OK, can you please get me the complete model code written on back of TV?
Also, what is the part number of old and new main boards?
OK, working on it, give me 5 minutes please.

Thanks for the info, it seems TV doesn't boot up fully and resets during boot up process and reboots again, this process goes on and you hear relay click on every time TV reboots.
There are two possible causes for this symptoms, either main processor chip on main board isn't booting up OR the display panel/ screen is short and protection circuitry shuts off the boot up processor.
As you mentioned the clicking process stops after 2 minutes that indicates main board is working and display panel/ screen is bad that need to be replaced, sorry about this news.
Please get the part number off of sticker pasted on metal frame of display panel to search/ google it to get price info that will help you to make decision about this TV repair or invest that money on replacement TV. Display panel part number would be like BN96-12676A or some thing similar.
No, a short display panel could damage the sustain boards, y-main and x-main, that is why protection circuit instantly shuts off power on process.
I hope these info will help. If you have any additional questions, feel free to ask. If you're satisfied, please rate me a 5-star at the top of your page. Thank you.
You're welcome, if you have any additional questions, feel free to ask.
OK, please check Va and Vs volts output of power supply board with multimeter as these volts go to y-main and x-main boards. If volts are available then try old y-main and x-main board one by one and reply back with the result.
What vols appear at Vs?
It should be approx 200V
