Re: Sony KDL-46S2000 - "clicks", 8 red blinks
So I plan to order another replacement main board & see if I end up with different or identical results.
Just not sure what else I should be checking/testing.
I'll post results once I try the next main board.
Any additional thoughts or insights as to why it may not be turning completely on are welcome.
Thanks again for all your help!

Re: Sony KDL-46S2000 - "clicks", 8 red blinks
Got the multimeter, took readings. All the measurements seem to match the values on the board pretty closely. Right at 120 in from power cord to power supply. All marked 18V areas reading right at 18 going off the board. Several 3.3 reading 3.3.
The only thing I did notice was that on the harness from power supply to main board there were 2 points marked UN REG 10.5. These seemed to be reading high - 11.9ish and these would drop dramatically whenever the "click-click" happens, then jump back up. Those marked...Leave a comment:

Can do.
Will try & get a hold of one tomorrow from one of my buddies.
Once I have it, what should I be testing?
Thanks guys!Leave a comment:

OK, OK, there's nothing to see here.
The issue is just me being a doofus.
The wires and tiny connector from the power button were tucked under a much larger set of wiring & I just didn't see it & didn't reconnect it.
Sorry for the boneheaded move there...
Got the original board to give 8 blinks as before.
I can turn the set on & off using the power button with the replacement board in, but it still just does the click-click like it's trying to power on.
The power...Leave a comment:

Ugh. OK - this is just weird. I put the original board back in & now I get nothing.
No green power light, no blinking reds, no response from the power button - nothing.
So frustrating.Leave a comment:

Re: Sony KDL-46S2000 - "clicks", 8 red blinks
OK- so I found a replacement board on ebay. I put it in, made all my connections, etc.
Now when I plug in the power cord, it doesn't do any red blinks anymore, but it now makes a click-click sound every 5-6 seconds like it's trying to power on, but can't (?). The green power light on the front blinks off & on every time it clicks.
It doesn't seem to do anything when I press the power button on the set.
Any thoughts/ideas?
Since it's no longer blinking 8 red blinks, is that problem solved?...Leave a comment:

Sony KDL-46S2000 main board/B board
Hi all-
Does anyone know if the main board/B board in a KDL-46S2000 is the same as/comparable to the main board in a KDL-40S200?
(or any of the other similar sets in this series?)
From what I'm looking at online, they appear to be "visually" identical, but didn't know if any of you with much more knowledge in this area might have an answer.
Any feedback/insight is much appreciated. Thanks!

Well dang- that's about as clear as it gets.
Thanks Bud, I'll begin the hunt for a replacement board.
Have a great week!Last edited by grafixlad; 06-10-2015, 10:13 AM.Leave a comment:

Bud-
Thanks so much for the service links!
I looked over all the PDF manuals related to the KDL-46S2000.
The triage & troubleshooting guide was very helpful & easy to follow, but all the flow charts just ended in complete board replacement. This helped confirm that I was targeting the correct board, but doesn't offer any details about testing/repair on the board itself.
The service manual seems to have more of the type of info needed for testing/repair, but as an electronics...Leave a comment:

Sony KDL-46S2000 - "clicks", 8 red blinks
This forum has been super helpful for me and has helped me fix my own TV as well as help a couple of friends with diagnosing their TVs. Thanks so much!
I received a "dead" Sony KDL-46S2000 from a co-worker. When you press power, it makes a few click type sounds, then gives 8 red blinks.
From all the info I've found, blinking red 8x is an IC5000 issue (?). From what I'm reading the problem involves the main board (B board, BU board - ?).
What I'd like to know is do I have to find & purchase another complete board? or is there a clear, straightforward... -
