These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit stage inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power led, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating, to many popular brand TVs and other devices. Viewing it in "Mosaic" will make surf easy.

It sounds that your TVs' timer function is set to 'ON' for 15 minutes time. Check it, and make it 'Off'. Refer its user manual for details.

It doesn't correlate to tthe trouble code in the users manual which are written. It sounds like a motherboard error. Try a cold reboot. Unplug the TV for 2 minutes then restart the TV and anything it is attached to. Unplug all first.

Green Flashes - Shuts off


Sounds like the green picture tube is defective. To confirm you can take the front grille and door off and tap the green tube lightly with something plastic, and not to touch any of the adjustment controls to confirm.

Takes about 5 minutes for picture to appear... Then every one to two minutes the picture disappears. It comes back on for 1 - 2 minutes then repeats. When set if first turned on, the stereo/stand-by light (red) flashes on/off until just before picture first appears .if your tv is very old than it might be due to crt getting weak crt base loose loose contact in power supply thanks
