投影畫面光暗閃爍問題

KingAlien

最近用投影睇碟，睇左個幾鐘後發覺畫面會有輕微一光一暗閃爍現象，就好似普通燈膽有時都會有嘅咁......
雖然唔係好嚴重，但都算明顯，尤其係光嘅背景....
應該關於投影機問題，因在無輸入之下，投影藍色畫面都一樣有閃....
部投影用左兩年，760個鐘，燈膽會唔會咁快打柴？
用上一代VW-60都未試過類似情況.....請問有無師兄見過呢種問題呢？請指教

應該係燈膽一或供電問題

Have you changed the HDMI cable recently ? I have similiar experience. It go back to normal after swapping the HDMI cables.

I did not change anything on my system.  It is also weird that it did not happen all the time.  During the past Sat and Sun night, I have watched two movies and there was nothing wrong.

I am just worrying that it is not a simple problem and can be solved by changing the bulb.

可能真係供電問題，因唔係次次都發生

Ching,
You are right. I have the Darbee. It has a defective power supply causing the blinking/flashing. It go back to normal after I have replaced a good unit.
