Hi there,

Well there are many things that you need to check -
1. check the main power plug(hoses).
2. check out the power cable - may be the tv cable is blown or getting shorted....
3. check the fuse on the main board - it's a internal fuse responsible to supply power to your TV it's located on the main board of your TV.... near the transformer.

or it's because of internal power supply failure... you need a multimeter to check it....

Post further comments for more help or information....

Good Luck!!

Thanks

The screen and the module both are showing red lights . The screen will not show a picture and I have tried to reset. Any options?


Press the VOL+ and Channel - button on the set and than the power button while holding the two buttons.
If the set starts then the fault is the error counter wich must be reset to 0. Max is 5 faults,if a sixth error is measured the set stops.

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.
