Question about Syntax LT30HV 30 in. HD-Ready LCD Television
I can turn on my tv and i can get sound but no picture. When I turn it on it shows the blue screen for about a second and then goes black.
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.

there is a bad capacitor in the power board
The Can shaped little device will have a domed or puffed up top on it the value is printed on the side you can , or have someone replace the cap and you should be all set

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.
