The tech form Sony is right. The blue CRT has an intermittent short and if the TV is more than a few years old, replacing all three tubes may be necessary. The cost is prohibitive. I see a LCD flat panel in your future.

Turn your screen drive down to green and blue tube.
You have a focus/screen drive control block that you can adjust each tube R/G/B

Error Code 5 flashes when unit shuts down


Good Day;
It sounds like the TV may have a shorted CRT, picture tube, but let's trouble shoot:
1. Unplug TV from wall.
2. Remove speaker grill, two on bottom, the screws are covered with plastic caps, right and left side on bottom next to floor.
3. Remove inner panel.
4. The blue tube is the one the right side, remove socket, with phillips driver, make sure it's not touching anything.
5. Plug and turn TV back on, if picture appears with no blue it's the tube.
6. If still shuts down, bad blue CRT driver IC.
CAUTION: Call a factory authorized service dealer to give you an estimate, if this sounds too hard.
Good Luck, Day, Big Irish.

Blue crt assmbly maybe?


its very possible that the blue CRT is horting the set out. Heres how you can test it. Remove the speaker grille and access panel behind the grille and you will see the crts. remove the blue crt circuit board from the end of the blue crt and make sure it isnt touching anything then try powering up the set if it doesnt shut down then you have found the problem and you will need a new crt. or you can switch the blue circuit with the green and try it iwth the blue on green and the green on the blue then if the screen turns green before shutting down you will know that its a problem in the blue drive circuit and not the crt. lety me know if you need further assistance.
