Desktop doesn't boot if connected to LCD TV. Reset solves it. LAChinese2012-08-16 00:45:49

I have an old XP desktop. It has only VGA port. If it connects to LCD monitor using VGA cable, I push Power button, post shows on screen, it boots fine to XP windows.

But if LCD TV connects to it using VGA cable, strange thing happens. I push Power button, the computer starts, I can hear hard drive spin, but LCD TV keeps black screen (no post), then LCD TV turns off, shows "No signal". If I push Reset button then, the computer starts to post on LCD TV screen, and boots fine to XP window. I tried 2 LCD TVs. The same happened.

I don't want to push reset button every time. it's tiny, hard to push.

Anybody had the same situation? How to solve it? Thanks.

 

 

显卡和tv不匹配 - 要不你就别关电脑了，用hibernate或者suspend/standby

I will try hibernate. Thanks.

你有没有什么高级键盘可以让你像笔记本电脑一样转换显示器选项的？

Keyboard is dead before I push Reset button.

Another question: why Reset solves everything?

预热了一下

Seems you are right.

I found the problem: undervoltage.

呵呵，降低电压温度有差别吗？

About 6 degrees: from 58C to 52C.

I'm an IC designer.

BRCM??

No,
