So I got the 7 blinks after a loud pop on my TV. I did some searching on the internet and got here. Upon inspection of the back of the TV I could visibly see that the SC board had a blown piece. Not sure what it is but it is a small black square and it looks like it has two pieces and they blew and are separated. Ordered a new SC board from Shop Jimmy but when I installed the board I still get the 7 blinks. I did more digging and found the attached guide. I started on slide 50 to check the VSUS, VDA and P15V. When I have my multimeter set to 2K and the reading comes back at 1.00 for all three checks, I believe I am okay there right?
I then go to Slide 70 and work through the steps, the first is to remove SC20 and C20 to see if the tv stays on with a 'black' screen. When I do this test the TV powers, I hear a couple clicks, then I press the power button and hear a click again but the screen doesn't do anything and there are no red lights at all. Does this pass this test or not?
So a couple of additional questions:
- Am I using the right setting on the multimeter?
- Is this the right trouble shooting guide?
Also, thanks in advance I am sure you guys get this stuff all the time and from the searches I did I can already see this is a great resource. Unfortunately I couldn't find the answer to my question in the searches I did.
