Hopefully someone has an idea of how to fix this problem. My TV suddenly cut out and now all it does is power up as if the screen is getting ready to come on, but it never does. All that happens is 5 blinks of the red LED on front.
This chassis was famous for destroying the diode stack in the flyback
the b+ at the hot will come up to about 80-90 volts briefly,
then the set will click off
if thats the case replace the flyback and readjust the g1 and g2
Hi, I have a similar problem with mine. but mine doesn't cut out. I tried keeping my finger on the reset button, on the remote control, and shut the TV off. When I put it back on, it's not flashing anymore. So far, it's about 4 hours and it's not flashing yet. Hopefully it will not. It's worth a try. Hope this helps.

These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices. http://electro-medical.blogspot.com/
If blinks continue without any pause, the main board is faulty......
Your problem is most likely a fried circuit board. I always connect my good electronic to a back up battery. but your problem might have been storm or surge related, I would take it to a repair center and get an estimate.

Count the blinks occur at one time switch ON, carefully. Do it once again, and make sure about the number of blinks. If the flashes are continious, non-stop, the main system control IC should be suspected. If you wish to get more details, check the site linked here. It has blinking codes detail to many brand TVs.

usually after 4 or 5 yrs EHT ( transformer that supplies voltage to tube ) becomes weak - then TV won't get ON.. means no picture no sound ..but LED blinks - in some TVs along with EHT 1 or 2 components like resistor, transistors, etc will also gets deffective .................. so solution is TV circuit board has to be checked to find whether only EHT is deffective or other components are also deffective.......... price of EHT will be between Rs.250 (US$ 5) to Rs.600 ( US$ 12) ........iam from bangalore ( 09986222774, [email protected] ) .....i don't have any idea about EHT component's price & service charge in your area........this problem cannot be solved by user unless user is a technical person having idea about components (resistors, transistors,diodes,...etc..), having multimeter , soldering iron & other tools...so my suggestion call TV service engineer or contact jvc service centre.........
Probably, the selftest fails while turning on. If this is the case, press input&menu buttons at the same time for 5 seconds, then the green led will start to blink. Let me know how many times the led blinks.
