Sounds like The main power supply regulator section circuit fault. Either it will be a separate board, or the part of main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here.

It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.

Thank you, after submitting my original post I went ahead and changed the fuse. That did solve the problem. The thing that really frustrated me was how inaccessible the fuse was. It seemed as if it was intentionally done so, so the consumer would need to take it in to get it changed. It would have been so easy to make the small access door a little bigger.

The Sony error codes go up to 7, so when the standby light flashes 11 times it usually means that one of the clock or data lines deep inside the set is shorted to ground. This is not fixable from the front or through the remote, so the set should be serviced by a qualified tech familiar with Sony sets.

The first thing in this unit is to check the ribbon cable that goes from the front control panel to the back ssb board, I would unplug and replug to make sure seated properly. Then try it again. There are alot of screws to take out but worth it if this solves the problem.
