Re: sound but no picture
Most likely - the CCFL backlight is not getting the power it needs to come on. You can verify by shining a light on the front surface of the set - if you can just make out a dim image, then that is it. On some sets, the CCFL can be seen through the vents on the rear.

LCD panel fault. If you wish to get some details; check the site linked here. Pull up older posts. http://electronicshelponline.blogspot.com/
faults & possible causes to LCD & Plasma screen are given with illustrations. You can get an idea about the fault to an extent. Faults to all LCD & Plasma screen are similar, irrespective of its brand and screen size.
Please describe the problem more accurately. Flashing red usually means 'stand-by' state, flashing blue/green - starting up. When (during that) do you have a sound? Are there any 'high voltage' sounds like soft screeching from the screen? Is it LCD or LED?
the error light sequence that you are seeing is indicating a "backlight error". Most likely you have a bad inverter board -the board that powers up the back-lights behind the display panel. They might be available via ebay if you are a DIYer, or you need to call for sony service.
I had a similar problem with my HANNSLounge 32", the screen switched on with green light but none of the front panel buttons worked (screen is black apart from showing the input source in the top left).
After powering off numerous times I tried starting up with a blank SD card in the reader and the tv cycled between red green and blue screens and then reset itself. (Some sort of firmware restore?) After which point I had a working screen again! (Will have to see how long it lasts for!)
