Compare the measured voltage to the Vsus listed on the voltage sticker inside the TV
There should be a sticker inside the tv which will look like the one I've uploaded here.
That will show you the correct VSUS voltage. If the voltage does not match that precisely, it must be adjusted to be as close as possible. Getting near it will show some type of picture, but when you get it exact, the picture will be correct. VR-251 is a variable resistor that you can turn that will adjust the voltage. That should look something like the second image I uploaded for you.
It sounds like the board may not have been bad, but it is possible to have more than one bad board. I would wait until you check those voltages to do anything.
Actually, if I were looking at it for the first time and the SC caused the fizzle/click, that's the first thing I would replace. That's a gift from the TV gods. When you say that it causes it, do you mean you can actually hear it come from there? The voltage drop after it turns on is normal.
Can you send a picture of the SC board?
What do you think about these two caps that I pointed to...
With physically accurate, perspective-shaded, red arrows?
Do you have any pointed up toward the sky from you laying in a supine position on the board?
My god... if the TV thing doesn't work out for you, you may want to look into becoming a photographer! I never get pictures this good!
I agree - no bulging. From the overhead view, it looked like a maybe.
I was joking - your pictures are so good - so detailed, I was asking if you have taken any from the position of laying on the board and looking up? Sorry... I have a dry sense of humor that is funny mostly to me.
OK... we will go through the steps.
On the SC-board, find and disconnect connectors labeled SC2, and SC20. Now plug the TV's power cable into a working outlet, and try to turn the TV on. You won't get a picture, but does the TV turn on and stay on, without flashing 5 times or does it stay off?
Ok. I don't know if you are getting ahead of me, or just trying different things. The 6 blinks is correct.
that's normal. Reconnect SC2 and SC20. Now we need to measure the DC voltage on pin 6 of connector P25, which is on the P-board. Push your red lead down into the connector so your lead contacts the pin, and leave your black lead grounded on any exposed chassis metal. Do you get 5V on that pin?
OK. So it is the P-Board. Verify by disconnecting each of the other boards, and re-measuring that pin each time. If it never goes to 5V, then the P-Board needs to be replaced. (part number ETX2MM747AFK)
Try all these combinations, please, still measuing pin 6 on P25. I think you did the first two but not the last two. I'm doing this the way we would objectively test if we were not making any assumptions about the TV. Assumptions would lead us to the SC board, but if you disconnect the SC-board and still get 2mV here, then it doesn't seem to be causing the (at least this) problem.
Then disconnect P2 to the SC-board first, Then disconnect P11 to the SS-boardThen disconnect P35 to the A-board Then disconnect P6 to the A-board
Correct. Nothing. I made a mistake.
