I push the turn on boton but the computer does not do nothing only some leds around the key board lights but then they turn off again

hi,check the CPU of your computer if it is booting properly.you can try to push the caps lock of the key board pressing the keyboard once the LED light indicator lights up then press again the light will turn off .This means that the CPU boots up and functioning properly.Check the data cable connecting the CPU and the monitor there must be a broken line there you can replace the cable or you can re insert the cable a loose connection can cause the problem.IF all are good and still same problem try to re insert the video card from the main board make sure to turn of the power before removing the video card...try this solution and post back if nothing happens after doing these solutions..good luck!

Try unplugging the the TV from the power outlet for 30 seconds to a minute and plug back in again. Try to turn on again. Some TV's have to be in a "ready mode" to operate by remote - so besure it is in that mode - or use the power button on the TV.

Good luck!

I have two 46" Sharp Aquos tvs,so i know this tv model well.Tv have Power and OPC LED lights flashes?Yes.Tries tv unplug,replug it back like about an hour later.The tv should be working again.This problems happen to Sharp tv alots,later on,should it happen again,just tries push the power switch on the remote again and wait the backlight will light up and tv will work again,some it will go back to Power and OPC LED lights flashes again,just push power switch again and wait,sometimes,u have to do this three or four tines to make the tv Tuner signal board to take to make the tv to work again.If u have to pushes power switches 10 or 11 times and wait and Power and OPC LED flashes lights again,it time to replace the tv Tuner signal board,that the board,where that take the tv incomming broadcasting signal cable plug into it.Tries websites like Shopjimmy.com,Ebay.com to buy a refurbish tv Tuner signal board for the replacement.

Power and OPC LED lights flashes?Common on Sharp LCD tv.Tv is still useable.Tv have Tuner signal board problems.Every times Power and OPC LED lights flashes.Just push the remote power button again and wait.Sometimes Power and OPC LED light will flashes require push power again wait again Power and OPC will flashes two or three time push power button and wait.Must do this two or three time before the backlight will light up and tv work.

if there is nothing wrong with the keyboard..than press num lock to make them work again ...(the first led should be always lit to work )the num lock ..is the button in the left upper corner of the digits area..

sounds like u have a bad mainboard.

Yes, if the leds are all lit and no respnse, then your board in the top counsel is faulty. Have you haad any power surges recenlty.? Power surges sometimes mess up computer boards. But yeah, it sounds like its bad tho. There should be led light on unless you start pushing buttons. Have you hit the "off" selection. If nothing turns off the led lighting, it sounds like the board might be bad...hopefully this helps

Not saying you are stupid but are you sure the batter is charged plug it in and try again if that does not work if when you power in on and the power lite lights up there might be on one of the F keys at the top of the keyboard it might say,CLD,LED or something like that try the clor that is push the button like FN or the key that is the same color as that and push the one that has the FN or the colored on and then hit the, CLD,LED and see if that works if not you might have to take it to someone.

open the control push boton and clean it one of the boton stoct.
