Let me tell you though, that the job is not for someone who isn't familiar with electronics.

The A3000 is set up differently from the A2000. You access everything from the front instead of the back. There are a ton of wires across the front of the unit that need to be moved out of the way. The good thing, however, is that none of the connectors are the same, so you can't possibly hook it back up wrong.

The light engine is set up differently from the A2000, too. When I got down to the SXRD chips, I thought I was screwed because everything was glued together. Also, there was a filter on the chip that looked like it was tinted blue, but the "red" one I got was not. The filter was also adjustable and was hard set with epoxy from the factory. No idea what that setting meant. I was prepared for the filter to have made a difference but so far it looks great.

Mark the placement of the SXRD chip before you remove it. Take pictures. Note the placement of it. You need a REALLY good #00 Philips head screwdriver to remove the SXRD chip. Then slice the epoxy holding the filter setting with a utility blade. When you put in the new SXRD chip, try to align it as best you can. The A2000 repair video online mentions nudging the chip with the TV on, but with the way the A3000 is set up, there is no access the chip. So get it as close as you can. Especially try to get the tilt of the chip right. Then tighten it all down.

When I took out the blue SXRD chip, frankly, it looked fine. No visible blotches. So I wasn't sure it was going to fix the issue.

My new blue chip was within 2 pixels in both directions of the old one, which I then adjusted with the service menu's coarse convergence(REGI) setting. I'll be doing the fine convergence later on.

I did take pictures and a video, but I'm not sure how useful they will be. I sort of panicked at one point and just started working on it without taking more video.

The reason I panicked is that when I put it all back together all I got was a green screen. I mean PURE green! No other colors. I had to take the light engine out two more times and disconnect/reconnect ribbon cables. Turns out that at least one of the SXRD chip cables was not seated properly. Once I re-seated them all, it came to life!

One of the video cables is really delicate, I took care not to damage it.

When I finally got the screen back on, the green blob was gone.

I did a lot of testing as I re-assembled to make sure that the TV was still working as I plugged in cables and routed them.

All told, it took me from 10AM til about 4:30PM. Spent $150 on the chip and express shipping.

Here's the video of the A2000 repair that was very helpful for repairing this TV.

Hi Shape, my Sony KDS-60A3000 has been growing the green blob for the last year and it's got to the point I need to replace the LCD panel. The pictures you posted will help a lot but I was wondering if you ever looked over your video to see if you had enough to post some video. It looks pretty straight forward, the only part I am a little vague on is the part about everything was glued together and having to slice the epoxy holding the filter setting with a utility blade. Is that the extra part with the 4 jagged edge tabs and if so did you glue it back? The seller you bought from has it mounted on that part but other sellers do not have that part mounted, it just looks like the picture of your old part. I guess the first step is to get the new part and go from their. Thinking about glueing a straight edge on the bottom and one side before I take the old panel off to aid in aligning the new one but don't know if that will work. I am gonna give it a try. Thanks

Sam, please try and document everything you learn using pictures and notes as well. The more users here documenting the process the more of us can avoid having to buy a new TV down the road. Let us know how you fair.

I did not glue it back. I have no idea why the filter on the front of the SXRD chip can move relative to the chip itself. I just put it back to roughly the spot I had it before.

Incidentally, I fixed the TV, and then upgraded to a Sony 4k TV a couple months later.

I never did get a chance to do that video. My recording was a bit of a mess, unfortunately. I didn't realize my camera would only record 20 minutes at a time, so it would stop recording and I wouldn't notice.

TV Won't Turn On

TV has run flawlessly since 2007, but now it won't turn on. My current bulb has less than 2,000 hours on it. The TV was working fine Saturday. Went to turn it on Sunday. The “power” light blinked green for quite a while, then switched to red, where it blinks in a series of 5 blinks, then pauses, then does it again repeatedly. No sound or picture, but at least one fan is on. I've been told that the problem could be the bulb, the lamp ballast and/or the power supply. I don't want to sink much money into a TV this old. Any suggestions as to the cause of the problem would be appreciated.

I read in the A2000 forum that its a lamp driver. Maybe that means a bad ballast? Try unplugging, opening the door, pulling the bulb, looking at it real good to see if it looks burnt (yeah I know this is difficult to judge), re-seating the bulb, closing the door, and power it back on.

Maybe just maybe you get lucky. That ballast/driver is betwen $50 and $100 on ebay and its a common part used in many sets. Good luck
