My tv's timer will not stop blinking which will not allow me to turn on TV

Not much info to go off of, and the video is a bit blurry. Try unplugging the tv for a minute or two, make sure to leave it unplugged to allow power to dissipate. Then try again. Otherwise I would suspect power supply problem.

Probably it is the poer unit

If you have a timer light blinking and won't stop the problem is not actually with the timer. It means that the two micros in the TV can't agree that all is okay to start TV. About the only thing you can try is pressing the reset button on the TV's front panel. Just a momentary press, you don't need to hold it down. The button is recessed so you will need a pen or paper clip to press. What should happen if TV is working properly is light should blink for about one minute and then stop, then you can turn on the TV. If light continues to blink set will not come on and you would need to get it serviced, there are many parts inside that can give the same symptom.

check voltage lines from SMPS.

Did you try this yet

SYSTEM RESET
If the TV will not respond to either the remote control
or the front panel controls and/or will not power Off,
press the SYSTEM RESET button with a pointed item
like the end point of a paperclip. The TV will turn Off
and the TIMER light will flash quickly for about one
minute. When the TIMER light stops flashing, you may
turn on the TV again. Changes you made the last time
the TV was On before you used the SYSTEM RESET
button may be lost, however, the changes you made
previously are not lost.
POWER/TIMER Indicator
The green light is a multi-function indicator. This light
will flash rapidly for about one minute each time the TV
is plugged into the wall electrical outlet, when power
is restored after a power failure, or using the SYSTEM
RESET button. Do not attempt to turn on the TV again
during this period. Wait for the flashing to stop and
the light to turn off, before attempting to turn the TV
on. While the TV is powered on, the light illuminates
steadily. If the TV has been programmed to turn on
automatically using the Timer feature,

There are several faults that can cause this. Shorted diodes in the high voltage, a bad flyback transformer, a shorted CRT driver IC. None of them are very easy to fix.

The blinking should be in a pattern of a count, pause, count. That is an indication of the problem circuit. Can you post that count please? That info will allow me to give you possible defective parts and costs for the repair.

Thanks,
