in my experiance of FIVE Blinks---AKB circuit (AKB) it is more often than not that the CRT is at fault .... especialy so the way you have described the symptoms .........
by all means check the video circuit on the CRT base Printed Circuit Board and check any high value resistors there too especialy ... i have know the resistors on the G2 / Screen go high or open circuit on the odd ocasion ..... i'll check any service notes i may have for that chassis just in case there is anything else worth checking or worth knowing about and if so ill add any info later ..... best of luck

oh i forgot to say ... on most Sony's with a faulty CRT, at the time while there is no picture push the teletext button on the remote control ..... if you get teletext ok but when you go back to normal picture it goes again this is also a good indicator of CRT faulty ... well rule of thumb in any case

There's 3 video driver IC's on the crt board. Use the tunner as ground and read the dc voltage on all three. If there all about the same, it narrows it down to the tube. Also you can try adjusting the screen voltage from the flyback to keep the set up.

continuos blinks :No reply from the jumgle ic. Data bus is busy and shorted to ground or held high ,IK video path is defective. don't say that's your problem. Do what Mimmi sais check those video ic's on the crt board like say you have 150v in the read 150v in the blue and say 50 in the green than take out the crt from the tube measure the green and if it goes to the 150v like the others than you have a defective tube .And the green more in the DVD is because the dvd player is not sony>> is it ?.
