Sony KDL-42XBR6 14 blinks missing DC to T-Con

Re: Sony KDL-42XBR6 14 blinks missing DC to T-Con

I had the same green vertical screen as second thumbnail on opening post. When it occurred I switched from cable HDMI to over the air digital. Picture returned to normal. I am using a Logitech remote. Used the Logitech remote to switch back and cable HDMI picture was ok again. Several days later my KDL-42XBR6 went dead with 14 blinks code. Replaced with two used T-cons. Still Sony TV is dead. Fuse F603 is open on my original board and last t-con board. Did not check on first t-con board. Pulled LDVS cable and code disappeared with all three t-con boards. Pulled both ribbon cables on t-con side with LDVS connected to t-con. I still got error on all three boards. Sent first board back. Thinking about using Coppell TV Repair to refurbish my original t-con board. Sending second t-con back for refund. Coppell TV does you-tube showing repaired working, send back if they think not repairable. Worried something in my TV is causing Fuse 603 to blow and my returned refurbished board will again have a problem. Is there anyway to isolate if the panel or BU board is bad also and maybe causing replacement t-con to go bad? Thanks Larry

I don't think you will get a "good result" from a sony with both cables from the tcon to panel disconnected. You need to only disconnect one at a time and see what the result is there after in terms of display and flash codes.... assuming, of course, that said fuse is good.

Fuse 603 is bad. Mine and replacement board had Fuse 603 bad.

Just set to Ohm mode and start probing.

I got a tweezers probe from Amazon. No Capacitors on flat boards were bad. What do I do next?

Both tab bonding caps are tested good? What kind of resistance reading are you getting?

Not sure where on two flat boards the two tab bonding caps are located?

So what flat board are you talking about then?

Tab bonding boards are the two boards where the two white ribbon cables from the T-CON attached to.

That is the board I am looking at, where are two bonding Caps on that board? Are you referring to all the smb Caps on the board?

See attached picture of the TAB BONDING BOARDS.
Also check the resistance between point 'A' and point 'B' on the T-CON board.'
When report the reading, make sure to show us if the reading is in Ohm, K Ohms, or M Ohms.
