Sharp aquos tv, model no. lc-70c-6500u, no audio, visual at power up, standby/power light flashes 2 times long, 5 times short, nothing else happens, what is this mean?


Sounds like main board fault. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. http://electronicshelponline.blogspot.com/ . In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.

Compaq proliant 5500 server wont power up


In my experience when a server/computer does absolutely nothing when the power button is pressed it is a dead processor. That may not be the case in your situation. It could be as simple as a defective power switch. Is the switch a soft touch or does it push in and click? Does the switch feel normal when pushed? One of the power supplies could also be bad. Do you have any good power supplies to test in the server? Were there any power outages recently that could have caused damage to the PSU? I would start with checking the switch. You could hook up a circuit tester and see if the switch completes the circuit when depressed. Also take a look inside the server and look for any loose connections on the mainboard. It is possible the wire for the power switch has come loose.
