If you haven't bricked this unit yet, or paid Syntax/Olevia's highway-robbery price to fix it (and pay STUPID prices to ship it to and fro), there is hope. Despite what Syntax and others say, it IS a replace-able part that can help get your TV to last at least another 12-24 months. During that time, you can save for a new, more reliable and reputable TV.

This is a well-known (at least those of us who had ours fail before yours) symptom of a bad backlight power inverter, which, for the LT30HV is a pain in the arse to get to (it's behind the main power distribution board and motherboard w/Pixelworks chip). If you can take apart a tower computer and install I/O cards, you can do this. These parts are made cheaply in China with 64 weld points that fail 100% of the time - and many other 'name' brand LCD TVs use this exact same CCFL backlight inverter. I'm working on posting the procedure somewhere on the net. The procedure shown in MoniServ's website is on a Kreisen set, which looks FAR more easily serviced than the LT30HV.

Good luck,

I think you have problems with the digital main PWB.

If the power PWB failed, turn off and change the pilot ligth to red.
