Set came in with Audio but no video/OSD. Backlights are lit. I can't see any video using a flashlight. I read somewhere where a blank screen could be a software upgrade problem but customer did not bring the remote to try a upgrade test. Surface mount fuses on the main board seem ok. Any ideas?

Re: Sony KDL-50W800C
Check for about 12 volts on each side of t-con fuse. -
Re: Sony KDL-50W800C
Check for shorted caps on the panel boards. Probably no tcon on this model.

Re: Sony KDL-50W800C
There is a T-Con board and the 3A fuse is open. I will replace the fuse and see if it blows.And yes nomoresonys that is the correct T-Con board.Comment

Re: Sony KDL-50W800C
I would check the resistance of the output side of the fuse with ref to Ground and als check the resistance of all MLC Caps first before putting in new fuse.Never stop learning

Re: Sony KDL-50W800C
I put in a new fuse and disconnected the 2 ribbons going to the signal board/panel. The fuse did not blow but the Sony light at the bottom of the set blinked Red ( It never did that before). Then I took the fuse out and tried it again and as before I had backlights and a normal lit Sony light at the bottom of the set. I'm leaning to something wrong on the T-Con board.Comment

Re: Sony KDL-50W800C
Does not blow the fuse with the ribbons hooked up. But with the fuse replaced, I can't power up the set by pushing the power button. Take the fuse out and I can power up. I will try to find a T-Conn board and reply.Comment

Re: Sony KDL-50W800C
Disconnect one side of the ribbon cables at a time and try powering on. If one side shows a picture, there is a panel fault on the side that doesn't power up.Comment

Re: Sony KDL-50W800C
Unplugging the ribbon cable that goes to the left side of the panel brings up a picture on the right side of the set. I'll check to see if there are any shorted caps on the source board that is loading down the T-Con.Comment

Re: Sony KDL-50W800C
It's a good half picture? what do you get when you do the other side?Comment

Re: Sony KDL-50W800C
Yes it is a good picture on the side that is hooked up and a bright white screen on the side that is not hooked up. And when I switch the ribbons-my set will not power up.Comment

Re: Sony KDL-50W800C
Its panel problem .if you open left side ribbon cable and display shows right side then your left side problem..do remove at right side as a same way and watch it.if left side problem then you need to block signal.for more send me a picture of tcon.i will guide youComment

Diagnosed this TV as having a failed main board which I've replaced with one from a KDL 55HX850. They are (supposedly) the same board.
Being 'Smart TV' it requires a firmware reboot when you swap out boards such as T-Con or main board. It starts with a black screen and flashing yellow and green LEDS, indicating it needs that firmware boot. The procedure described all over the web is to put the software into the root directory of a FAT32 formatted USB drive and it should load that up once plugged into USB1 port. But not for me. I can see the LED on the USB chip flash for about... -
