Hello everyone! I have a huge problem. My powercolor HD4850 has this problems: First time i plugged the card, there was some kind of little smoke at the end of the card where is the power cable connector, somewhere there, fan was spinning all fine, i turned the PC off. The PSU was a thermaltake 750W , tried other cards and works perfect... so isnt the PSU. But now: - No smoke or anything else similar - Doesnt Post, no image at all. - Fan doesnt spin - The D1601 light Stays ON, the other doesnt. - I touch the card and isnt hot at all, it is like is not doing anything just the led diode is on. Ok, now what i did to figure this out... i researched, and the D1601 light means overheating protection, so that is why the card just doesnt turns ¨on¨ , and there is no heat at all, even with fan no spining. The card just protects itself from being turned on. So what i did, is trying to get the card really cold at my freezer, using the anti static bag that cames with it, of course, like 10 minutes at freezer. Ok, later i plugged the card, and the red D1601 light wasnt on anymore, just the 2 lights came on for like a second, like at every not faulty 4850. I touched the part where the voltage regulators are, and it was very very hot!!!, not the same case when the D1601 led stays on, that is COLD. But the fan wasnt spinning either, and no signal. What happens here? Is there any way to fix this, i know ppl from my place that repairs Vga´s , motherboards, at electric stage, like replacing transistors, capacitors, voltage regulators, etc. I hope they can fix this, i dont know what the error is, i guessed one of the voltage regulators is dead, and thats why the overheating? Maybe some of you knows more about this kind of errors... thanks!!!
