    Thank you very much for trying but I am not following the information in the pdf. file. The tv is an Astar brand and that board has nothing to do with the power supply for the LTV-3001 Astar flat panel HD lcd tv.

    Please try again I really need the help.

Have to turn tv on and off multiple times to get it to start without distorted picture and high pitched sound.


Same thing happened to my astar tv. Your power supply is going bad, or at least some of the capacitors are going bad. Eventually it will go bad altogether and you won't be able to turn it on at all. You need a new power supply.

I need a replacement circuit board for my Astar LTV-3001.. Mine began to smoke... and I don't allow smoking in my house...


The failures on these LCD's are due to defective capacitors in the power supply. There are about 23 capacitors that will need to be replaced to restore the LCD power supply functionality. Check the picture to see where the capacitors are located, the power supply on your LCD is not the same but similar to the one on the picture just the capacitors are place in a different order.
Let me know if you required further assistance.

Astar ltv-3001 powers up with sound no picture


If your TV has more then 1500 to 2000 of use, chances are that the power supply is starting to fail if you have to unplug the TV to be able to turn it ON. There are about 23 capacitors that might need to be replace to fix it.
I repair them, let me know if you need further assistance.

No pitcher


The power supply is not providing enough voltage to the back inverter board due to leaky or dry capacitors in the power supply.
The power supply will need to be replace or repair to restore the LCD functionality.

Have sound but no picture.


The power supply failed. It could also be the lights malfunctioning but is very unlikely.
The 5 volts DC line is not providing a proper voltage to the circuitry. 12 volts seems to be working since you have audio.
