iMac is not showing anything... Please help

Hi,

I got a iMac A1220 2210 model from my friend, who had this PC unused for a long time... I was trying to make it work, but i cant understand where the problem is...

When I power on my iMac, the first 3 of 4 LED is ON except the LED#4.

I thought that there must be problem with the LCD. Then, I tried through the external display also, but no signal on external monitor too...

Please help me to fix this....

Pull the GPU and do a hot air reflow of the chip. I've had a 70% success rate with this fix on this model. Here's how to get it out: iMac Intel 20" EMC 2133 and 2210 Video Card Replacement

How to do a Hot Air Reflow? I have opened up everything and cleaned the old Thermal past. Now, should i keep it under the sun. Will that work?

I just got to know from my friend that, the iMac faded out suddenly when he used for the last time and never showed anything again... And that's what i'm working on.... Please Help thanks mayer...
