1 Boot Loop / Cycling (Most Common)

​This is the specific "signature" failure for this board.

• ​The "Samsung" Loop: The TV turns on, displays the "Samsung Smart TV" logo, stays on for a few seconds or a minute, and then shuts off and restarts automatically.
• ​Random Reboots: The TV works for a while (perhaps 10-20 minutes) and then freezes or reboots on its own.

​2. HDMI "No Signal"

• ​Input Failure: The TV turns on and the menu system is visible, but when you switch to an HDMI source (Cable box, Game console), the screen says "No Signal" or "Check Signal Cable" even though the device is on.
• ​Port Specific: Sometimes only one HDMI port fails, but usually, they all fail simultaneously if the main processor is damaged.

​3. Clicking / Failure to Power On

• ​Relay Clicking: When you press power, you hear the "click-click" of the relay, but the screen never turns on. It may just click repeatedly.
• ​Note: While clicking is often a Power Supply issue, on this specific Samsung Plasma series, a shorted Main Board is a very common cause because it fails to send the "VS-ON" (voltage switch on) signal back to the power supply.
