My graphic card problem mention in this thread.
Actually this GTX 460 die before 3 years so I send for RMA. Then after that, I use it for another 3 years then it dies.

Start PC, no display, no error, no beep code. Got fan.

Some people say it is the power problem.
I found 1 SMD spoil and some ppl say because of power problem so this spoil, replace this SMD is useless because it will spoil again until the main problem fixed out.
Do you think what is the problem?

I also got another GT 220 card and recently I talk in this thread
https://forum.lowyat.net/index.php?showtopic=4761720
It is quite strange, after last month I report for that problem, then it can work for about 1 month and now it come out same problem again.
In that month, at start of 2-3 days, when I boot up it got this problem but then I do a second boot then it ok already. Then after that 2-3days, everyday first boot also ok no problem until today got problem again and second boot also cannot.
Do you think what is the problem cause this?

01. the picture of GTX 460 shows that smd fuse + resistor are blown. Reason, 1 or 2 mosfet have short.

02. the GT 220 indicate that got some leaking on the GPU chip ball (BGA - Ball Grid Array) reball will solve the problem.

03. Monitor power supply board - depend on brand

04. Yes I do repair Motherboard for laptop

GTX 460 & GT 220 not worth to repair

As for the monitor part, you cannot find at jalan pasar, especially ceramic & resistor, for mosfet you can search for cross reference

For GT220 problem ( GPU chip ball (BGA - Ball Grid Array)), this will happen when switch on the PC? After it able to run and show display, it will work for whole time until I shutdown?
Because today when I switch on, it able to run again.
So it will sometime can work sometime cannot work until doing the reball?
Make it heat will help?
