T con board is responsible for picture image and aberrations are usually caused by an issue with that board.

Audio is OK, Video NO


Hello,
It sounds by the description that your tv has a defective T-CON (Timing Control) Board -this is evident by the 5 flashes and the fact that the screen was working ok, then going black then repeating.
The board can be bought usually on ebay but, only if you feel comfortable in replacing it yourself, otherwise a sony service tech needs to be called to repair this!
Good Luck
