    Exactly the same problem. Turn it on, quick blue screen, no picture, but fine regarding sound. That's what I get for going for the best CHEAP thing available.

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,

SOURCE: syntax olevia lt32hv 32 inch lcd tv. power surge now no picture

The electronics are known to go bad with these TV's, and I'm looking to buy someone's junk TV that has a good screen, rather than have to throw it out.   
(So if anyone is out there with a 532-B12 that isn't working, send me a message!)

Yours might be worth fixing - however I know sadly that parts are nearly impossible to get for these TV's, and the manufacturer is virtually impossible to contact.
If you DO manage to contact anyone (manufacturer or otherwise) who can source or supply parts, PLEASE do let me know - it's been nearly impossible for me, and I want to replace my cracked screen in my TV.
If you can't, please let me know - I'll gladly give you a few bucks at least to salvage the screen from your TV, to transplant into mine, rather than turning it into junk on your curb.

My Sony KP-46WT500 screen shows the tv image in blue only for a few seconds, then it goes completely blank (as if it were off). Do I need to replace the bulbs?


It is rear projection TV that use 3 picture tubes of red-green-blue to show color picture on tv front screen.
Do you see standby red light blinking when TV shuts off after showing blue image for a while?
If red standby light is blinking, please count it how many times it blinks, there would be 3 seconds pause between blinks so count pause to pause and post it here to find out possible solution.
Thanks.
