My Sony tech says it's most likely a bad cable box. Try a DVD and if the DVD is fine then it's for sure your cable box. Needs to be replaced by the cable company.

Most likely this is caused by a defective main board. Changing the main board will fix the issue about 95% of the time.
To be absolutely sure, the voltages need to be checked on the power supply. If they are not the values listed in the service manual, then you should replace the power supply instead (accounts for the other 5% of the time).

That symptom may cause by the main board or t-con board, I suggest you do software up grade first.

I just fixed one with the same problem. The light flashed 13 times.
I had to cut one trace on the hv board to one of the lamp drivers.
There is a slight but barely noticeable darken line across the screen but the tv stays on now and the picture is good. I don't
know if the lamps can be replaced but why bother now.
