I have not had that exact problem, I'm sure you have tried powering off for more than 10 minutes, for some reason that has alway fixed my issues with the same model you have. Good luck!

Why is it when I turn on the tv the power lcd light is green and then starts to blink red and will not show a picture?


Because it has a problem. Most likely in the power board, although you shouldn't take it as granted.

The number of red blinks is actually an error code.
Not a very informative one,mind you, but you can try counting and searching.

Can't help more with the information I have, sorry...

Sharp lc-22sv6u won,t power on. no green light.


Sound like the TV is in protection mode. This happens when a part goes bad inside. the TV turns OFF to protect the other parts from being damaged.
Most commonly it's a power supply related issue. A bad capacitor or transformer on the power supply board is to blame.
For a do-it-yourself fixer with electronic experience, a Service Manual is the best for trouble shooting the problem down to the bad part. Normally, you can find it over the internet for less than $20.

Lc -30hv4u


This is just the beginning, it will happen more often and at some point in time you will have the same problem some of us are having, it will click the monitor power light will lite up green and the ACV box light will come on green for a second and then go red again and the lcd screen will go blue. Unit will not power up. I have this problem and it has started the same way, I did the same thing and nursed it for about 6-8 months now no matter what I do it wont come on, I have tried no power for a day, cleaning, banging acv around tapping, slapping cursing and still nothing. So if you ever find this problem I would love to know what the fix is and who can perform it, I live on disability now and cannot afford just to let somebody charge me out the wazoo and say they cannot find the problem or tell me something like it needs a whole new ACV just because they don't know what to do. If I learn anything I will let you know also.
