Have TV Questions? Ask a TV Technician
Hello there and welcome to Just Answer. My name is ***** ***** I will be assisting you today. I am an engineer with over 30 years of electrical and electronic training, repair and installation experience. I will try and answer your question accurately and precisely so that we can get you on your way.
Can you tell me which board you are referring to as the motherboard?
Ok, that is the A board. Not usually associated with 10 blink errors.
Do this for me please: unplug the TV and wait about a minute. Then look for the VSUS connections off the power supply board. These are P2 and P11. Disconnect them.Plug in the TV and turn it on. How many blinks do you get?
Ok, unplug, wait one minute.
Put P2 back ONLY. Leave P11 disconnected.
If this model has a power wire that runs from the SS to SC board, disconnect one end.
Plug back in and turn on. How many blinks?
This one doesn't have that SS/SC wire - just checked.
That would be the SS board. That's the one on the right.
Try this though. Unplug as usual. Pull P11, reconnect P2.
Turn on, how many blinks.
Sorry for the delay. Laptop probs. All good now.You are right SC3 to SS3. Yank that from either end and repeat the previous two tests i.e. P2 in, P11 out and then P2 out, P11 in.
Sorry about that.
Ok, then your SS board is bad. That should be the TXNSS1LNUU board.When we disconnect the board causing the 10 blink code and get a different code, we have found the bad board.With SS connected and SC disconected, we get 10 blinks.With SC connected and SS disconnected, we get 7 blinks.That indicates that the SS board is bad.
Do one more thing for me to be 100% sure.Put everything back. Remove P2 and the SC20 connection on the SC board.
Turn on the TV. How many blinks?
Replace the SS board. Try www.shopjimmy.com for good used boards.
I'll be here if you still have issues.
Sounds good.Have a great day.
I am sorry to hear that. Can you repeat the isolation steps we performed last week with P2 and P11 please?
Hi there. I'm confused. You were unable to perform the previous tests?
So you ordered a second SS board?
Ok. So you have replaced the SC board, the SS board and the P board.If you disconnect P2 and P11 do you get 7 or 10 blinks?
Ok. When you get them, reply and we can continue.
