Tip #2: If your LCD display shutdown after a few seconds and you find that there is nothing wrong with the invert board, then you might want take out you trusty digital meter and perform a test on the pico fuse.
For your info, a pico fuse should not register any ohm reading. So if your test result indicates one or more ohm figures, then it's a good idea to get a new pico fuse replacement.
Tip #3: Defective amps fuse can also lead to this problem. So naturally, the solution is to replace it, BUTwhat if the amps fuse fails again?
Instead of replacing with a brand new one, what you should do is examine all semiconductors, particularly those situated in the inverter board area.
Tip #4: Check the switch mode power supply, specifically its output voltages. If they are not steady then your LCD display will definitely shutdown after a few seconds of switching it on.
