I purchased Christmas of 2010, so it is almost 15 months old.

No picture before it turns off.

Thanks!

Expert:  Tim Nolan replied 2 years ago.
Ok so some bad news it looks like....There are a couple of different things that could cause this problem, the first is the power supply, and the second the main board. Also either sustain or scan driver board can cause this problem. To know exactly what board is the cause, you need to have electronic repair experience, and test equipment. If you have this let me know and I will assist you in the troubleshooting of this tv. Otherwise you will need a repairman at this point. You can expect a bill of anywhere between $300-$500, this is a good average, however it could be more or less.

I am sorry I don't have a quick fix or easy answer for you on this one, please let me know if you have the skills and tools and I will be happy to assist you. Also please let me know if there is anything else I can do for you.


If you would like any additional information or have more questions please don't hesitate to ask!

Please remember to press the ACCEPT button when we are finished, it is the only way I can get credit for helping you. I want you to be 100% satisfied so please, by all means ask any questions you might have on this subject. Positive feedback is always appreciated.

Thank you,
