It has a flashing red light and when i unplug it the tv still has a flashing light

Red light flashes 6 times and stops after switch on - iFixit

Check connections to boards, but probably not economical to replace boards even if you can get them.

power supply issue

Red flashing light on tv. Power went out

sometimes a leaky filter capacitor in the power supply primary section could caused this problem,or a loose solder connection in the power supply section

I have a philips pf50 9630a/37 tv may come on or it may not unplug it and take a chance then comes the 6 steady red flashes followed by 3 rapid red flashes the screen had been completely replaced by philips a year and a half ago

turn tv on picture comes up 2to3 seconds later tv blacks out then stand by red light flashes 4 times in a row repeatedly..can not turn on or off when stand by light starts flashing but before tv blacks out you can turn tv on and off repeatedly and picture and sound work.You have to unplug power cord for 30 seconds after stand by light comes on to get tv to turn on.

I unplugged my Sony for 36 hours and it now works.

If you put the "CR" board back on, the error code will once again be 5 blinks. Your problem is likely the TV's IK blanking circuit. The Kine driver ICs on the CRT sockets boards CR, CB, and CG need replacement along with a few components in the 200 volt supply to the circuit.
