You need a new inverter board... it sounds like the transisters or capacitors in the last stage of fireup are gone. I'm no pro, but I've fixed a few lcd monitors with that very same problem.

Here's something crazy you may want to try at your own risk... I play in a band and very often our guitarist spills beer on his effect pedals. These are digital pedals with very similar components to that of a computer. When they finally give up and stop working, I take them apart and pull out the circuit boards and run them for a few seconds under warm to hot tap water (goes without saying, but NOT salt water, hehe) and then let them dry out for several days. When they are TOTALLY dry and reassembled they work fine again... it washes the ber off and gets rid of any shorts until the next time I have to put them through detox!

My guess is that the sticky juice is shorting the transistors, which are basically voltage controlled switches... if they don't switch then your monitor lights won't fire up. OR if they are getting too much power because of a shorted cap, they would switch back again, leaving the screen blank.

Again, I'm no pro and it's at your own risk... but considering it was juice... if I were you and could identify the inverter as the problem and planned to replace it, I would try that as a last resort before spending the cash. Make sure your inverter is completely dry before re-installing it!!!

anyone with more knowlege care to comment?

My kids accidentally spilled orange juice on my laptop. It continue to work for a little but now the screen is black. What can I do?


Sugar is the worst. If you had immediately unplugged and removed battery you may have had a chance. Once sugary drinks get in it's almost a death sentence for electronic devices. If it's valuable take it to a Qualified Computer Tech, if not right it off as a learning moment.

Toshiba Satellite L455-S5000 monitor blackout but works w an external monitor


This is a tricky situation, any fluid that ends up inside can cause a cascade effect, hours, days, weeks and even months before the full efects are known. You could end up changing the screen and down the road face major failure in the motherboard. Under the circumstances I would consider a laptop replacement.

MY LAPTOP WENT BLACK AFTER I SPILLED SOMETHING ON


Its better to show it to technician bcz it seems the motherboard inside lost bios flash and its unable to detect old settings so that everytime it reboots checks bios and then reboots again to flash it. Better show it to a local technician. One other way is to try booting it in safe mode and then check if it works.

Taken it back to your repairing shop, ask for brushing of the motherboard with CTC, and also proper cleaning of Cam and Sound points. Hope so this will work.

Spilled juice on my H P Pavilion laptop keyboard, keyboard is not working at all. Please help!


Do you have an HP Accidental Damage extended warranty? If you do, you can call HP's tech support and get it fixed/replaced.

If you don't have the extra warranty, you can try to carefully pop the keyboard keys off and carefully clean underneath as the contacts below the keys are possibly stuck in the down position.

You may have to take it to a service centre and have a technician open up the laptop and see if it can be cleaned and try to "unstuck" the keyboard keys.

Spilled Grape Juice


To give it a good cleaning, you will need to remove the keyboard and clean anywhere you can see juice or feel stickiness. You can buy the expensive computer cleaners, but I suggest 50/50 rubbing alcohol and Q-tips. Remove the battery and C-mos battery to make sure there is absolutely no power to the machine what so ever. After cleaning inside, you will want to give it a good 24 hours to dry, ensure that there is no moisture before applying power. If the juice reached the bottom of the machine, you may need to remove the screen, split the cases, and take the motherboard out, in order to clean the bottom side of the board. If you leave juice anywhere on the board it will gum up, and the acids in the juice will corrode and detierate the circuitry on the board causing a motherboard failure. Now the keyboard, in order to thoroughly clean the keyboard, I suggest that you spray a good amount of the rubbing alcohol in the keyboard, shake it or blow it out with air, then take paper towels and daub up the rest. Repeat this two or three times, then let it dry approx 24 hours. Sometimes the keyboard won't recover after a spill and will need replaced. If it works properly, then, after using the keyboard for a while, you will notice if any of the keys are sticking. Take the sticky key or keys off and clean them individually. I know it's alot of work, but it'll teach you not to keep open drinks around your laptop. It did me, I've ruined one machine, two keyboards, and thoroughly cleaned a third very expensive machine of mine to keep it working, but I finally learned to drink from a sippy around my laptops.

Heavy to press keys


replacing the keyboard is an easy fix ,
just order one on ebay ,
so much of the keyboard has little nooks and parts that
even if you take it out and wash and dry it the paste will still be present.
just search for a pavilion dv8000 keyboard
they are around 40 including shipping.
