5 blinks indicates that your system has detected fault on Chroma board (Chroma board is the only board connected at the rear part of CRT). Often there are loose connection on IC terminals. Re-soldering of ic terminals can fix your problem.
im not finding an 8 blink error code in the service manual only 2,4, or 5. the tv will shut down and blink an error code. it will blink the code fast and repeat itslef. if you can tell me what the code is i may be able to assist.
Yes, the blinks are error codes. I would not bother trying to figure out what they mean, I can tell you right now. Expensive repair. Average repair costs are 1/4 to 1/2 of the TV's current worth. Most likely a bad transistor. The average expected life span of a TV set is 3-5 years. After that, stuff starts wearing out fast. Time to move on.
If the screen won't come on then the diagnostic will never show. The 4 blinks is an error code. If the set is older than 12 years then it doesn't owe you anything, you got your money's worth out of it. Average life of any tv from that genre is 8-12 years. It's time for a new set, or take it in for an expensive repair ( pending parts availability).
This is the most common death mode for TV's. The high voltage is
acting up. You set is not quite 10 years old right? Can be
fixed, but involves replacing the Flyback transformer which is not
cheap. It is a toss-up as to whether it is worth putting the $200
or so it will cost to fix into a set that has limited expected lifetime.
Its the BULB people! You need to change it every 3 to 5 years! I have had my sony 55" for 6 years... I had Best Buy come out 3 years ago, changed the bulb... it worked fine. Just started flasshing and shut its self off and back on again. Time for another bulb.
