    Open up the cover. Take the memory out and also take the CPU out as well. With a can of air blow out the memory slots where the memory would normally be. Then blow on the contacts of the memory itself.After you take out the CPU. Blow out the socket as well as the pins on the CPU with the can of air. This is to make sure that specs of dirt and dust aren't interferring with the motherboard.

Upright freezer orange and red light on but green light off can you advise? Frigidaire freezer.


Draw fan has failed, temp unreachable over the past cycle of 24hrs, turn your unit off for 24hrs and defrost it, restart and should work fine for a few days, if so, replace fan and defrost element only. Call service tech for this unless you are clued in on this work, not that costly.

Xbox 360 problem


If you can still HEAR sound, but can't see. Check your Audio Video Cable.

It's the colorful one (red, white, yellow) (red, blue green, white, red)

Make sure the connections are secure into the back of the TV as well as the connection to the back of the Xbox 360.

LG LCD TV Standby Light Flashing Red Continuously


I have had this same problem twice in the past 3 months. So far both times I've been able to get it back after a week or two. I'm not sure what works, but unplugging and detaching the antenna and cable and waiting a few days seems to be the key. In both instances, I unplugged it for a few days then plugged it in for a few days and repeated the processes until I eventually got the steady red led. Both times prior to the red led the led would flash red then green and make a clickiing noise for several hours before I was able to get it working again.

Power LED blinks red


it is a bad fan. it also could be a power supply. Quite often the real problem is dirt clogging up the fan(s) to the point that they need to be replaced. Operation of the set in a dirty environment is not a good idea
