Re: Sony Bravia KDL-40XBR6 14x Blinks error

I tried the Reset last night and it appeared to do nothing. Did not have a chance to get pics or test other inputs yet.

I got stripes on the original mainboard I did component repair on but not with the replacement board from the 46". Both going into 14blink HFR error. Have not tried HDMI or any other inputs yet either. When I did have stripes they were across entire screen and static.

Cables appear to be connected properly and I have not found any bent pins, etc.

Thanks,

Hello all, I've been troubleshooting some issues with our TV and got to a point over the weekend where I just was not sure whether I should get a replacement T-Con board or consider the LCD potentially faulty and just get a new TV.

Background -
Sony Bravia KDL-40XBR6 we have had since late 2008. About a week and a half ago came home one day and it would not come on. Was getting 3-blink error (mainboard or PS). I did some troubleshooting and it appeared that PS was ok and mainboard had issues. I was able to track down at least one blown pico fuse on it and a mosfet bank...

Hello, my name is Aaron and I do a little hobbiest electronics stuff occasionally. Simple repairs of my own equipment, as well as very basic design and implementation for projects including some microcontroller stuff. Hoping to get some more experienced help when needed.
