Super Bright LED Torchlight
A friend of mine gave me a powerful LED torch light and it uses 3 AAA cells. It has a single white LED and could produce super bright white light. The advantage of this torchlight is that it can be used to shine on dim LCD panel even without turning off the main lights in the room. Sometimes we do not know if there is any display or not in LCD screen if the inverter is not working. Certain LCD set when have problem, it will have very dim display and even a normal torch light could not really see those faint display. If you intend to buy a torch light for this repair purpose i suggest that you choose the brightest one as it could really helps you to clearly see those dim display in LCD panels! This remove the guessing game and you instantly know that the mainboard is working and the problem is in the inverter board most probably the supply voltage line pico fuse already open circuit due to shorted components.
