Per Sony site, unplug for 3 minutes if your T.V. picture goes out and you have blinking red lights. If still have a problem and T.V. is plugged into a power strip, then unplug for 3 minutes, then plug directly into wall. The power strip could be bad. (https://us.en.kb.sony.com/app/answers/de...)
It could also be a backlight problem of some sort.
If you can view T.V. again, and want to see error codes, do the following: Turn T.V. off. Quickly press "Display", "Channel 5", "Down Volume", then "Power". Press "Power" again if nothing came up on T.V. See error codes. Press "Power" again, then again, to return to normal T.V.

I have same problem with my T.V., Sony kdl32xbr4. I already know I have a backlight error of some sort, since part of the screen is slightly darker. The codes verified that. I also had the 6 blinking red lights with no picture at all. Unplugging for 3 minutes did reset the picture. Error 6 was listed on my T.V. as a backlight problem. Though I do not know for sure if Error 6 is the same as the 6 blinking lights, since the blinking light happened when the picture went totally out. The backlight partially went out a few month ago with no blinking lights.
I will eventually need to take my T.V. in for repair but do not currently know what the cost will be. I am hoping it is worth repairing. It has been a great T.V.
kaushik what exact model is your TV?
I had the same problem. Did all the simple fixes to no avail. Then I tried tapping the back of the TV and it has been good for a while now. Maybe loose wire or something but worth a try.
Kaushik, you have a bad power supply board. Find your part at buyqual.com as I did fixed mine 2 days ago it was doing the exact same thing.
I had this problem after not using me TV for a few weeks...I had my Xbox one plugged into hdmi 2 .Played all night with no problems.The next morning I ran into this problem here being discussed.I tried many things but what worked was me unplugging the hdmi cable.I had noticed that the TV kept a lot of residual energy while it's plugged in...Now I unplug it each time after using and ONLY plug it in now AFTER powering on my TV...
I did what Chris said ,and my wife named in the back lightly and walla its working again!! Thanks Cris!!
