Installation Gacun st-by LCD

Damage IC stand-by LCD can be replaced with Gacun commonly used in television tubes (3 wires) or disposable Gacuc IC STR (5 feet) How to install the TV tube Gacun 3 feet:

• Attach the red wire on tranfo switching.
• Attach the black wire to the ground great Elko.
• Attach the blue cable to the photocoupler. If the blue cable is not installed, then the output voltage will be more than 3.3 / 5v - although the position of VR has been minimal.
• Our experience Gacun do not need to be plugged cooling, because the power to st-by just a little.
• Noteworthy is Power Fet good isolated so as not to stick to the chassis / body LCD
• Special Note: If the current at power-on voltage 3.3 / 5V drops, then VR can diajust bit (voltage will not rise, remain 3.3 / 5v). If it still drops, then add a little ajustment try again .... and so on until it drops again.
