Blank screen dell vostro v121

Hey geniuses!!!
** managers, please, of that question os not compatible today to that "laptop tech support " **
Hey,just got an cheep faulty dell v131 laptop, which power up,but have a blank screen,, whatever i try..
Already try..
1. External vga screen to see if something wrong with the laptop screen with press the Fn+f1 key
2. reset bios defaults by taking out the cmos battery
3.try different sticks of ram at the both ddr slot..
4. Sprayed with contact spray & toothbrush (without cmos battery and ac charger power to mb)***{{the laptop keyboard has a coffee or something spill under it... But the mb itself dont have a coffe signs}}***,in addition, the laptop turns on,but the screen is black, usually when something spill and hurt something, the laptop will not power up totally..
.....
5. disconnect ac and battery for about 2 minutes, and then press the power botton 20 secs,and then plug it back and turn on
$$$what I put attention to,,.. Is that if im take out the cmos battery //all the ram sticks, and turn the laptop on the laptop is beeping( with different beep codes as need to !!!!! Which means that something still alive!!! $$$

So,any suggestions will be just great!!! Im thinking about reflow with hot air gun,but this is if ill be sure that the mb. Gone and i have nothing to lose or worse... Thanks!!!

check the HD activity leads, if it has the pattern like booting (light blinking for 30-45 seconds, then intense blinking for a minute or 3, then intermittent blinking"), if this is the case then it's certainly booting: try plugging in the secondary before booting and waiting, it may not engage from the bios, but windows should enable it (hit only enter after a good wait, may log in). F1 may be enabled to not have to use the fn key, if you haven't tried it by itself after the previous instructions. May want to even try unplugging the LCD connector for giggles.

If none of that, reflow is your last chance but use the baking method instead, it's a lot safer, be careful and don't get HASTY! let it cool for a loooong time before touching. After that, part it out on ebay (not the mb, and the lcd as-is). Good luck but be prepared for no joy.

Hey! Thanks for replay!
Actually, im try it also without hd before the post,in additional,the hdd itself totally working via external sata usb adapter...
And the hd led when it was connected, not blink or lit at all...
The just lit leds are; under the kb,power,, the 3 hotkeys led between the lcd and the keyboard ,and the wifi led. That's it

yep, sure sounds like a blown graphics chip, good luck with the reflow.

Thanks, btw the (2) fan at that pc,seems to be pretty clean(comparably to other poor laptop like hp tx 2 that the fan n the heat sink was dirt and dusty..
Just hope that im really can back it to life!!! Thanks dear!!!

got it fixed!!!! THANKS ANYBODY!! SOME CABLES WAS LOOSE LITTLE

lol
