Question about Sony KV-28FX60 28" TV
I had the same problem, my telly was showing error code 5, led blinking 5 times and then the telly enters into standby mode. There is a great site with pictures of this telly and I found the answer here:
Error Code 5 - Tube Gone
Hope it helps.

My first guess is IC 702 in the crt drive circuit. You could open the back and unplug the "C" board from the back of the crt and then power it on. If the set comes up and you have good audio that will isolate the problem.
If IC 702 is the problem you'll have a couple of other things to check, R533 .47ohm 1/4 watt fusible resistor and C541 22uf 100v both on the "A" board because they tend to stress when IC 702 begins to leak. Replacing IC 702 and not the resistor and cap could cause 702 to fail again.
If IC 702 is not the problem then it could be the flyback.
Hope this helps!
