It is rear projection TV that use 3 picture tubes of red-green-blue to show color picture on tv front screen. Do you see standby red light blinking when TV shuts off after showing blue image for a while? If red standby light is blinking, please count it how many times it blinks, there would be 3 seconds pause between blinks so count pause to pause and post it here to find out possible solution. Thanks.
that's very hard to fix, you need to monitor every test voltage pin if is in normal. try also replace crystal capacitor thats one monitor with the jungle IC.
Its either blue tube or bad componet on blue CRT board hertes how to know disconnect Blue CRT board connect to neck of blue tube turn set on see what happens if set come on and plays then this lets you know if it is a problem with tube/video ic on crt board. If set shuts back off different problem.
Based on service manual info, it cant blinks 7 times as per symptoms, please count again blinks. It can be 5 times.
If its 7 times blink, Horizontal Deflection stopped in this case. If you want to repair it at your own, please let me know to guide you further but it is necessary you should have knowledge of electronics.
