This typically means you have a bad capacitor, you can inspect for any swollen or bulging capacitors however unless familiar with desoldering boards best leave it to a repair technician.
Five blinks to Sony Wega denotes a fault to its AKB
circuit (automatic kine bias), the timer/standby indicator blinks for about 30
seconds then goes to the self-diagnosis function. Something is wrong with the
video. Check video out, Q705, 732, 761 and other components on the C board,
also check Q218, 219, 220 on the A board. In addition, unit could be in IK
blanking, try turning up screen slightly.

The flashing light is "Code" for diagnostics. Count the flashes before it pauses. Some Sony user manuals will have the answer in the troubleshooting section of the manual. If you don't have your manual, http://esupport.sony.com/US/perl/model-documents.pl?mdl=KD30XS955
My Sony trinitron has the stero lite on steady and standby lite flashes four times then pauses and repeats. Can you tell me the circuit/condition causing the set to not turn on.
How many times red light blinks when TV lost picture? There would be interval of 3 seconds in red light blinks so count pause to pause and let me know.
The light that you see flashing is the timer light. It is flashing because of the lack of red, green or blue. This would explain your color issue. It could e caused by the CRT (picture tube) itself or a bad connection to the CRT or a color driver component failing. Either way you need a technician to locate the issue. If its the CRT and it is out of warranty, most likely it won't be worth the repair.
