It sounds to me that the unit has a faulty inverter board which could be due to an overheated/bulged capacitor. I would send in a claim on it to the factory if it is still under warranty.

If you pay for shipping I will send you my screws. Maybe a buck or two will cover it in an envelope. I just removed them last night as the TV is being junked for the parts. Email me.

cable might not be compatible with the TV. try another wire or use regular video cables. see if you can change channel to 3 or 4 for input? I bet the computer might send a signal that makes the tv flutter like that.

Hi Alfred Grace,

First of all, thank you for posting your question here at Fixya.

Based on the symptoms you've described, I don't believe that the backlights are already faulty. If backlights gone to malfunction, that are permanent, but in your case you've said that the TV power up fine for half an hour, this is an indication that the fault not came from the backlights but from the inverter boards. Inverter boards are the one giving high voltage to the backlight to light up, it has a built in protection circuit that will activate once there's a malfunction on the board to avoid further damaged because of high voltage output.
If you would like to fix it yourself, I would advice you to replace both the slave and master inverter board. I saw your board at shopjimmy.com. Click it HERE for the replacement. Replacing these boards are not technical, all you have to do is to unplug the unit overnight to drain any voltages from the power supply board, disconnect all connectors and then put-in the new boards. No soldering required. If just in case that the inverter boards are not the issue (I'm pretty confident that the power supply board is working fine), don't worry, the link I've provided accepted return, the fault is on the power supply board.

Hope I helped you.
Have a nice day!
Good luck and take care!

The pop has been generated by the explosion (literally) of an capacitor from the power board of the tv. When that happened the power source has been shorted and, if you're lucky, it went in protected mode. Fixing that is a relatively simple job - all you need is a soldering iron and a basic experience in using it. Follow this

If you're unlucky the entire source has been fried and it will have to be replaced - here's a good one

Any time a TV has no power is your power supply that needs to be replace. Check for blownen caps.

Thank you
