Power problem The system wont power up. All connections are fine. No response from unit. What do I do

Check for power at unit . If there is power to unit check for blown fuse on circuit board or bad board .

Problem solved! The support at Busbi actually turned out to be quite responsive. Reply as follows:

Thank you for contacting support, sorry to hear you are experiencing issues with your tablet.
Can you please try a factory reset on the device, Connect the USB lead to the tablet and your computer please leave for 10 minutes remove the cable power down the unit if the unit powered up, press and hold volume + also power keep held until you see the bees, release both keys.
Use volume - navigate down to wipe data / factory reset
Press power

batterys are loose with intermittent power to thermostat circuit board place a tightly folded aluminum foil to about a 1/4inch square and place it between or at either end of the AA batteries. This tightens the connection and makes for a better contact.

Check the back of the unit for speaker wire shorts, if everything looks fine suspect the output ic's in the stereo.

Pull out your batteries and check them. The UPS wont restart with out good batteries.

the speakers plug/outlet is usually at the back of the computer you will have to open up the computer to check the lead attached to the rear of the input plug make sure the connection is good
or you might have to clean the dust from your computer dust causes static which causes your computer to overheat and all sorts of problems
be sure to wear an anti static earth strap before touching anything inside your computer try cleaning your computer of dust using a fine air blower from a compressor making VERY sure that there is no MOISTURE in the air line specifically around the CPU central processing unit and your SOUND CARD dust causes static to build up in a computer causing it to overheat any many other problems
hope this helps

Try this to get it at-least back on with your PSU that fits in the case. open up your computer case, locate your power supply. With the AC cord still plugged in , unplugged the connectors to your motherboard from the PSU and wait about 10secs. Then replugged them in. This should power on your PC.
Also, You wanna check around where the PSU connects to the motherboard and make sure there is no damage. No burning,Discoloration anything that could be potential damage.
Hope this works atleast to get the PC booting up.

hucknannie, Power down the pc and monitor. Then disconnect and reconnect the VGA cable a few times to the rear of the pc. then turn system back on and re-boot. If your "PINK" screen still there, then you may need to have unit refurbished with new "cold-cathode-fluorescent-lamps" or have the internal "switch- mode-power supply/ccfl-inverter-supply" inspected and repaired.

check fuse inside unit

The sparks that you specified looks like.. a transformer problem.. And yes they charge 200$ for labor!! The cost of a replacement transformer is around 120$
