Hi,

It is possible that there is video/picture, only that you can't see them because it is dark.

Your Astar LTV-3001 is an LCD TV and makes use of backlights. They are CCF Lamps powered by an inverter. Normally there would be several CCF Lamps and very rarely do all go out at the same time. What then could possibly have happened is that the inverter powering these lamps is defective since it is common to all.

A way to check is to run the TV AS IF everything is alright (albeit nothing you can see). With the use of a flashlight, shine the light obliquely to the screen. Press your remote's volume control up or down and try to see if there would be a semblance of the sound level indicator. If you can see something no matter how dim or dark, then you have just confirmed that it is the CCF Lamp inverter that is at fault.

If you have confirmed that there is really nothing even with the use of the flashlight, then it has something to do with the LCD panel or the video interface internal to the TV.

Unfortunately, either fault would require that you be familiar with electronic components and circuitry, the use of a DVM and a soldering iron. Should you not be comfortable going this route, you may need to seek the services of a qualified professional or an authorized service center.

Hope this be of help/idea. Pls post back how things turned out or should you need additional information.

Good luck and kind regards.

    Hi again,

    Another thing that might be worth trying is to do a full/hard reset, that is unplug the TV from the mains for a couple of hours.

    Cheers.

Screen goes black immediately after astar logo screen comes on


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.
