Samsung 943 series monitors
When it lights up, it turns black as soon as it comes out. Generally speaking, the problem of the high-voltage coil is a problem when it is shipped from the factory. It can usually be solved by replacing it with an improved product on the market.
If it doesn’t boot, the button light flashes… and other faults, many of which are caused by the leakage of the buttons. Generally, just replace the buttons with new ones.
Common problems with Samsung monitors at present:
1. In addition to the above, MCU program, EDIT, power supply…..problems, many capacitors are bulging and pregnant, due to poor heat dissipation, causing all kinds of problems, there are twill interference, there is a cold machine that does not turn on…etc. Wait, these are replaced, generally just fine.
2. Program or lamp, etc., so that the color turns red.
The above are the common problems that I have encountered in repairing Samsung LCD.
