Remove battery. Maybe faulty? Try another cord/charger with the EXACT same specs. Reseat the Memory Mods. has the AC jack been damaged by pulling on the cord? Try plug in and at the laptop's AC jack "wiggle" the AC jack plug. Any change?
Tv turn on?Front LCD panel LED power light indication flashing?Yes,than the power supply board is dead,that the board where the power a/c cord plug into it.Tries websites like Shopjimmy.com,Ebay.com to buy a refurbish power supply board for the replacement.
This problems very common on Sharp Tv.Do ur tv LED power light turn on solid first.Few mins,than LED,OPC flahes.Power LED,OPC flashes,push power button again,do this at leat 5 or 6 times somtimes the backlight will come back on and work.The power LED,OPC light flashes,turn off/on more than 5 or 6 times don't work.Ur Tuner signal board is dead,must replaced.
Below is a link to the service and maintenance guide. This will serve as a reference for disassembly. It is free to use, copy and print. It is in PDF format. I would check the voltage at the tip of the adapter to make sure it is putting out the proper voltage. I have seen plenty if failures with the HP laptops at the DC jack area, in most cases these jacks are connected to the motherboard by a cable and plug, which makes them easier to service than the soldered type. Here is your guide........
when the yellow led flashes is never a good signal... you should check the manual's printer to find out the error code meaning "4 yellow flashes and 1 green) Usally it's the waste tank that is full, in this case you need to:
Push “resume” for 5 seconds for canon IPXXXX.
Push Power switch then remove power cord.
Insert plug power cord while pressing “power switch” at the same time.
Push Start/reset by step 2 continue Wait display shown “0′
Push + change display from “0′ to “1′
Push color button 2 times
Push Power switch again , Printer will print 1 page
disconnect the battery and just keep the ac power connected. hold down the FN button and hit the power button. if some lights falsh and the computer shutsdown in 4 - 5 seconds its a bad motherboard. If you get other light lemme know. Call dell tech support and get a dispatch made if system shutsdown right after the lights flash. You can also try the chat support at www.dell.com/chatsupport
keep a phillips screw driver handy when you call as they might as you to disconnect the hard drive, CD drive and other cards like thememory card and wireless card to check if they are not causing the issue.
