Elektrotanya for electronics experts
It sounds like a blank raster with retrace lines (no picture) which would be some kind of video fault. You could check C-board (Video OUT (IC9001-IC9003)) and progress from there. Also, being a CRT set, there may be a few bad solder joints everywhere - especially around the flyback transformer, and, with set unplugged, look for ruptured or bulging electrolytic capacitors in the video, vertical and HV areas of the chassis. Also check the horizontal output transistor(s) and associated tuning capacitor(s) to make sure they are OK (if they are, you can rule them out as suspects). It's a start.

5 times Red LED blinks means Lamp Driver Error. (KDF-55WF655)
2 possible reasons, either Lamp is gone or Ballast Supply got bad.
Replace lamp first, in most cases it solved the problem.
How old is this TV and did you replaced lamp recently?
