It sounds like the blue CRT (picture tube) is failing. The part number for this is 8-733-575-25 but you will need a technician to replace it for you as there is mechanical and electrical alignment to with with it. At that point it probably isn't cost effective to repair the TV. Please take a few moments to rate my answer. Thank you.
FIVE Blinks---AKB circuit (AKB), the timer/standby indicator blinks for about
30 seconds then goes to the self-diagnosis function. Something is wrong with
the video. Check video out, Q705, 732, 761 and other components on the C
board, also check Q218, 219, 220 on the A board. Also unit be in IK blanking,
try turning up screen slightly.
6 blinks is usually associated with failure of the horizontal
deflection amplifier - which shuts down the high voltage system as well.
The repair requires testing to determine the exact parts that have
failed. There are, for example, a few hundred parts and a section of
the Jungle IC chip involved. So, repairs could require something as
simple as replacing some inexpensive passive components OR as
complicated as replacing the jungle chip (very expensive).
most of the time it's the horz. transformer and transistor.
