Hello Everybody!

I write from Hungary and I'd like ask a question in connextion with a mac.
I've a a1181 macbook white, but this is faulty. It turn on, but it has only white screen. It doesn't boot, and I don't hear the apple chime. I tried the SMC reset, PRAM reset, with other LCD and LVDS cable but it is not repaired.
Have everyone any idea?

Thank you!

What is the number of main board? (Example: 820-2235)

The number of the board is 820-2279-A.

Front LED blinks w/o memory (when memory modules removed)?

Sorry, my description from the faulty is not correct. The mac is turn on and I hear the apple chime. The sleep led works than normally start up with memory modul, but the screen is white only. (no apple logo, blinking folder or other)
I am hear the one beep sound without memory, in this case the sleep led blinks once. (than normally start up)

Very high probability that bad VGA chipset.
You can try it to heat in hot weather, 300 degrees, 10 seconds.

Thank you! I will try to heat the GPU.

I tried to heat the GPU, but the condition of the board didn't change. Can you give me any idea?

Thanks!
