Hi Matt, I know it's been awhile, but I'm making one last ditch effort to fully confirm everything you said. To start with, I replaced the T-Con Board, and it didn't correct the problem. My T-Con Board IS ATTACHED as shown in the picture, with the two ribbon connectors. Since it is connected, are you saying DON'T buy a main board, or are you saying since the T-Con is connected to BUY one? Thanks so much for all your help Matt, I wouldn't have been able to get this far without a good guy such as yourself. If I can't repair, I'm going to part out the boards anyway, if the front panel is bad. Please refer to the picture for clarification. Is it option 1, or 2?
1. T-Con Board attached, DO NOT buy main board.
2. T-Con Board attached, DO buy a main board.
Again, thanks so much for everything, I look forward to your final answer. Take care.
Tim
Sometimes the T-con board is part of the TV screen. In this case it is not. Of course, you know now that the T-con is not the problem. The main board will need replaced.
The main board is also called the signal board. In many cases I refer the" main board" as a signal board.
The front panel is fine!
You are doing fine!
Matt, thank you so much for your time and concern. I will now seek out a main signal board to replace my broken one. You're a real lifesaver and I'll let you know when the repair is complete! Best, Tim
Hi Matt, I had a bear of a time finding a board, but I'm hoping that I got the right main board. I used part number 8-597-661-00, along with my TV model KDL46VL160. It matched up a letter/number combination on my board as FSS-BRF-CA422T. I bought a brand new board for $78.00 shipped direct to Hawaii. I bought the part from TVserviceparts.com.
A used board on Ebay matched the other numbers - A1506066C, and 1-876-561-13, but it didn't have the other information as above. I'm hoping and praying that three out of five numbers found on mhy board will be enough to have covered the accuracy needed to match the part. Also, I chose the new part over the used one, and only paid maybe 10 or 15 bucks more.
So, that's it for now, Matt! The part will arrive in the next week or so, and I'll let you know how it went. I truly wish these part numbers would all go away in favor of just one, but what the hell, it's how it goes, I guess. I'll be in touch!!! Best, Tim
Hi Matt - I had hoped to be the bearer of good news today; however, I do not have the news I wanted! Additionally, I think I'll give it a go on the diagnostics side of things and say that I have a bad screen?!?!? That's purely a guess at this point, but I mean, what else could it be, right? I replaced the main board a few minutes ago and I am still getting the same vertical lines - with sound, mind you. I also, if you remember, replaced my T-Con board to no avail. HOWEVER; I would appreciate it if you received the message I have for you today, and that is a hearty THANK YOU for doing what you do - and that is, I believe, giving out free, sound, best of the best knowledge you have of TV repair. I suppose I can part out whatever I can get to, as well as sell the T-Con and signal board, too. The worst is, I've been out of a TV while paying for cable - but that is definitely on me, especially letting it drag out as long as I have. Do you have any other ideas as to what I should do with the broken TV? Or is parting it out too much of a hassle, etc.? As always, any and all info is appreciated! Matt, we didn't get it done on this one, but we sure did give it a good shot. I thank you very, very much for the wealth of information you share with others on a daily basis. Once I get myself up off the floor, looks like we'll be taking a ride to Costco for a new TV set. I hear the "smart" ones are pretty good! Take care Matt, and I will check back for any tips on what to do, to also see if my diagnosis is correct, and any other closing info you'd like to offer. Wish I could buy you a beer, but just try to suck on the USB port real hard to see if that'll work. Seriously, you're the best. Look forward to hearing from you! Best, Tim

Hey lines on the screen can't be from your main board, it's either from your panel or from your T-Con Board. The panel is not worth fixing but the T-Con is. To give it a try you can get one here and 1564 648 Sony BT3 Board . Also remember when you replace your T-Con Board to connect everything correctly or ales your problem might get worse.
You have a bad signal board. I repaired one of these under warranty some time ago. This was the repair for your Sony TV then. Thanks for asking and show a few hands of support!
Matt - I'm Sorry, I didn't know we couldn't use the "Enter" key, and thus, the reason for the multiple posts. That is my Sony Bravia, same model as the original poster. Is this what you were referring to when you mentioned bad signal board? If so, what would be a good source (and, if not too much trouble, a part number) for the signal board? In keeping with the "FixYa" tenets of doing something to repair your own belongings, I'm considering doing the repair myself. I've done some other electronic repair in the past on a minor to moderate level - but I have a good command of mechanical knowlege; not so much on electronics, etc...for example, I don't have a scope, nor do I know how to use one. However, if a signal board isn't too difficult to replace, I think I could do it. Getting into the weeds and a dozen or more steps tor get into a given piece of electronics is not a problem for me. I am detail oriented and can handle replacements...I just would need a little direction and I can usually take it from there, notwithstanding perhaps a few forum posts :) Matt, thanks for all you do, and i look forward to hearing from you soon. Best, Tim C
Matt - In case you didn't see it, here's a picture of my Bravia with the vertical colored lines. My unit is about three to four years old. Thanks! Tim C. 
It is also known as the main board.
Let's start simple. Find shop jimmy.com.Find Sony. Type in model number.
This TV may have different main boards, in this case you will pull the cover off the back. Find your board number there.
This board will have all your RCA jacks and RF connections. Don't fret if out of stock, there are other sources. visit you later.
You may be looking for an A-BU board.
Wow, Matt - THANKS for all that great information! To further clarify: 1. I am assuming that you agree with my assessment that, since I am having the same problem as the original poster, we are talking about the same remedy: Replacing the signal board. I'm also assuming that what I'm saying is correct, since you gave me all the info about the signal/main/possibly A-BU board. 2. Sorry to ask again, I know you took a lot of time and care in answering my question, but I have to ask: Assuming you've read about my experiences in MY original post, do you think this is a DOABLE thing to do, replacing the signal/main/A-BU board? I'm just trying to get a little more confidence before I proceed. 3. I'll start looking at "shop Jimmy" for my board, and I'll return with my results...4. AGAIN, THANK YOU SO MUCH, MATT!!! PEOPLE LIKE YOU ARE GOLDEN, IN MY OPINION. Chatt soon. Tim
Matt - As a follow-up, a lot of folks are saying vertical colored lines are a problem associated with what they are calling a T-CON board. Is this the same thing we're talking about when we say Main/A
Sorry, got cut off...Main/A-BU board? Thanks in advance...Tim
Matt - Here's an update to the update. At your urging (I believe), and the urging of others, I opened up my TV so I could better identify my parts. It was a good learning experience, and I'm more comfortable with changing out any boards, etc. Here's what I came up with: First, the main board is part number 8-597-661-00. This is the one with all the RCA jacks. Secondly, there is what I would term "Power Supply", as evidenced by the various windings, etc, part number 1-876-466-12. Thridly, I have a "Backlight Inverter Board", part number A1536222B. Any of these sound like TCON/A-BU/Etc., that I would need to replace? Also, there is a part that is completely covered by a metal cover with heat sink ribbing, as well as a long component that I can tell has electronics on it alongside the left edge, all the way up and down that side. Thanks again, Matt, I look forward to your next exchange! Best, Tim
The board with the RCA Jacks is your board. Possible board #s are, A-1643-243, A-1641-959, or A-1650-034.
a T-con board generally has problems turning on the TV. You are experiencing a checkered problem correct? If this is the case, the main board is bad.
Thanks, Matt. I actually tried to replace the TCon board because I had seen it in several other places where techs suggested it, plus it was the cheapest option. It wasn't the TCon. So, I'll be changing out the main board. To clarify, my problem isn't a checkered pattern, it's just vertical lines as in the photo above. Also, I checked all the copper colored connection tapes at the top (don't know the actual name), and there was no discernable problem with those 8 or so connectors. I'm off to buy a main board, and thanks, Matt!!!
A-1506066C? or 8-597-661-00?
I see it. It's the 8-597-661-00. However, what does FSS BRF-CA422T mean? Is that an alternate part number???
Usuall that may be the actual board Number. Next, look for this number. A1564648A or A1643243A.
Matt, one more question: I'm having a little difficulty because I'm getting two completely different answers from different people. From a guy over at ShopJimmy, he stated that it was a TCon Board, and if it wasn't a TCon board, then it would be a short to the LCD panel and not worth replacing. He didn't mention anything about the main board. Can you please explain in brief your thought process on why it would be the main board, and if you think you know why the other guy said Tcon or none? Thanks Matt, I really appreciate you hanging in there with me. Take Care. Tim
Ask the tech at shop jimmy if the T-con board is attached to the LCD panel. If this is the case, then yes, it is not worth repairing. In my case of repairing under warranty, they did send a new panel. That was not the problem. And yes it did have the same vertical and lines you show. Sony sent a main board (signal board), and that repaired the TV.
Remember, sometimes the T-con board is built into the LCD panel. I do not remember in my case of repair, if it was built into the LCD panel.
As we speak, the main board is not available at this time. This is a good reason to believe, the problem is the main board. You have to be a Sherlock Holmes in this case.
Yes, the one I repaired (Sony, of course) had the checker board pattern as you described.
Almost always, a T-con (Timing Control) board will have on/off problems.
And, I'm sorry, I think I just messed up the order for this thread. See the top #1 solution for my response
Hi again, Matt - Well, I've waited and waited and waited, and finally recieved my part for the TV. However; this part is nothing like I expected. Apparently, I recieved the "tuner", a slim silver box that needs to be soldered in place, as opposed to the "Main Board". Straight up, Matt, do I need to return the tuner, or will installing the tuner on my current main board fix the problem? I am so discouraged it's not even funny! Hanging in there. Please let me know. Thanks :) Tim
Send the toner back. You need the signal board. The signal board has all the RCA jacks as well as the tuner box. Show me the back of your TV set. I'll be waiting.
Hi Matt: I think it goes without saying that you've gone way above and beyond for guys like me who order wrong parts, etc...Haha. Well, I'm just very thankful for your help, and I'll pass on the gesture by paying it forward. Here, for your consideration and information, is the picture of my TV set, and of the main board itself. Best, Tim
I hope you can find the correct board, all numbers should match, in some cases you may use a near match. Let me know how it goes..
Matt, can you please give me a better idea where to look on the board for the correct number? There are a bunch of number/letter combinations, and it's hard to know which one is the right one. Thank you...Tim
Matt, do you know where I can find the correct number on the board? Thanks, Tim
Find "shop jimmy" on internet. Find on top right, it will say "for best results type in parts number. Instead type in your TV model number. You will find "Main Boards". There will be three or four boards, study these and you should find it. I'll visit you later.

You are welcomed. In few cases I have heard of bad panels. I've only encountered one. Sorry to hear the repair was not good. The best thing to do, as you have invested money in this, is to store this TV. There may come a time, you may find another TV of the same model. There is that good chance, someone will just let you have, no cost. This happens often with me. Be patient, you will be rewarded soon. Take care. Sincerely, Matt of Martins TV Repair.
