Check the connector/cable between the logic board and the T-CON board on the LCD panel, also check the fuse on the T-CON board, it may not be receiving the 12/5vdc for for the VCC.

ONLY BLINKING POWER BUTTON ON THE DMONITOR. NOTHING ELSE IS THERE.


Hello,

This is a common problem with the Samsung 204B units that have been in service for a few years. Parts called capacitors in the power supply start failing and causing the board to not start correctly. The blinking power button is just the power supply restarting over and over. The monitor is easily repairable, you just need to replace the 5 capacitors that have failed. Here is a link to a page that shows how to open the monitor, get to the power supply board and what to replace.

Replace the screen with a known working one. If it shows display then it is the screen which is broken, if not, then it could be the port on which it is connected.
