Troubleshooting Radeon AX3850: Guide to Measuring Output Voltage and Comparing Values

Question

Hello. I have a problem with my desktop computer. No image is displayed on the monitor. I blame the graphics card for this, because after removing it and restarting the BIOS settings, I connected the monitor to the graphics integrated on the motherboard and everything is fine. The external card...

Hello, you tried to connect another card or it works on it, this way, at least you will eliminate the damage to the slot. Checking the voltage in terms of voltage will not give you anything special, you still need an oscilloscope and a lot of knowledge about the work of graphic image processing devices, but maybe one of your colleagues will typically speak. greetings

At the moment, I cannot plug another card into the slot, so I wanted to check it with other devices, but now I do not know what is going on myself, because today my equipment from the internal card did not fire at all. The strangest thing is that the CPU fan itself starts when I turn the power on, and nothing at all happens when I try to turn on the computer. Maybe someone had a similar problem, or knows whose side might be the fault?

Charger? In the event of a standby power supply failure, symptoms such as automatic switching on of the system or starting problems can occur. You have not given your buddy what powers this computer. With more complex systems, a good power supply is the basis.

It is not a latest generation computer. Parameters: Gigabyte G41MP-S2P 2 GB RAM DDR3 Intel Core Duo 1.6 GHz And it is powered by this miracle:

Dummy power supply. Well, first, unscrew it and see what the capacitors on the secondary side look like (where the cable bundle to the motherboard comes out). If they are swollen (convex top), they should be replaced. There is a good chance it will end there and the computer will wake up, as long as something else hasn't been damaged. If something is not clear, give a photo of the power supply board from the elements side after removing the cover from the housing, then we will advise you what to do next.
One more thing: if there is a chance to borrow a power supply from someone, you can try to see if the system will stand up under another power supply. If it works, the matter is clear. Depending on your skills, either repair the old one or buy a new one.

Each board beeps for failure test sounds, the number of beeps indicates an error or damage to a component of the board.
Look for the code description for the beeps.

Well, I would clean this heat sink, maybe for this the card died because it was overheated

A strange thing, because the power supply has come back to life and everything is fine when using an integrated graphics card. The external graphics fell on 99%, because when connecting the replacement card, the computer fired without any problems. Can anyone help me repair the card by myself?
PS. The album did not make any sounds

meaverick · Answer

I have attached a description of the pins and if there is a loudspeaker on this board, check if it has sat down?

sochinho · Answer

The pins for the loudspeaker are free, and I can't see the device itself, so I don't think the board has one.

meaverick · Answer

If you have a loudspeaker with a similar plug, you need to put it there, but see the computer, there should be a free plug somewhere, moreover, I don't know, maybe they don't install such things now.
But if you go to some computer store, tell the guy what it is, if he has a spare, he will give it to you or sell it to you.

you can give it to diagnostics. Some services can do it for free
