Question about Hisense Televison & Video
SOURCE: blue discoloration
I have replaced alot of these light engines for this problem. Yesterday I received a letter from Sony saying they are going to give an additional warranty to have the optics replaced. I just checked, your model is one of them and Sony is replacing the optic block under an extended warranty, regardless of the purchase date, until the end of October 2008. Contact Sony for an Authorized Service Center in your area or go to this site to read about it: http://esupport.sony.com/perl/news-item.pl?news_id=185&mdl=KDSR60XBR1 Have this repair done on your set and it should save you about $1300.00 to $1500.00 on the repair. Hope this helps.

Astar 30" LTV 3001 ....These TV's have a cooling problem that causes premature electrolytic capacitor failure. De-solder and Test all the 2200uF-25v, 3300uF-35v and 1000uF-10v caps in the power supply (center board, back of TV). Use a good LCR meter that will read 3300uF or better, Replace all bad caps with 105c rated caps. If you don't have an LCR meter, replace all the mentioned caps on the PS. If fuse on board is blown, also replace the F9222L regulator IC chip. Mounting a small cooling fan on rear of TV over the PS will help keep your new caps from failing again. This requires holes in the stand bracket and the rear of the TV, power can be supplied from a 14V source near the bottom of the PS board.

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,

STOP!
The unit has a fault on its power board and sustain board.
It turns off because the sensor is preventing some component from bacoming overheated and catching fire or damaging further components. Seel professional repair.
