Facing TV Problems? 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.
If this model has an SD card slot, have you ever used it?
Ok. Unplug the TV.Disconnect P11 and P2 from the power supply board. Plug in the TV and turn it on. DO you get 7 or 10 blinks?
Ok, plug it all back in (P2 and P11) and turn it on. Do you see LEDs on the SS or SC board?
Ok. Unplug just P2. P11 should be plugged in.
How many blinks? 7 or 10?
Ok that would indicate the SC board but that is very rare. I think something else is going on.
Plug back in P2 and P11.On the A board - the ones with the video jacks are some connectors. Remove A31 and A32.
Turn on the TV. How many blinks. Also tell me if the TV starts up.
Ok, I was having a brain cramp earlier. SC failures are very common. I was thinking SS.The SC board is connected to two other boards. The SU and SD boards. One or both of those can be bad OR the SC board can be bad. It is important to determine which one is causing the problem becuase if the SU or SD board is shot and you buy a shiny new SC board, the still damaged SU/SD can pop the new board..
So I want you to follow the procedure shown here: http://screencast.com/t/fNejj14pboG
Just to clarify, P2 and P11 should be plugged back in along with any others you may have disconnected.
Sure. Anything metal.
Ok. Almost sure it is the SC board. Hold on for a second please.
Replace the SC board. The part number is ***** and unfortunately, finding one is going to be difficult. I did a cursory search and could not find anyone with it in stock. There are a few repair kits but that's a lot of work - if you can solder, you could try that.I would set up a Google alert for that search and hope one pops up.It's an older TV and spare boards are rare.Let me know if you still need help.Steve
Not hard to swap out. Good luck.
Hi I'm sorry that you are still having problems. Was the green LED lit on the old board?
Ok, then I'm wondering about that replacement board. Unplug SC20 and C10 which is on the C1 board. PLug in and turn on. Do you still get 6 blinks? Or 8?
That's a bad SC.
Let's check all of our connections especially those to the P and A boards.
Ok, hold on please.

I would imagine that the rules and policies vary. I would give them a call.
