Nothing comes on picture blank


Ok
A few things to try
1.) Check the laptop on an external monitor, do you get a picture
2.) Is there power to the laptop from the battery and the charger? Try to see if the charger indicator lamp is blinking green rather than steady green
3.) Can you hear hard drive / fan noises and are there any lights on the laptop?

If the charger is blinking, indicates that power is not making the circuit, check tightness of charging port, if tight, assume fault on motherboard / blown main fuse

If picture on external monitor and not on laptop, assume backlight on screen dead or possibly the inverter

If no noises from HDD or Fan and No lights on laptop, then fault with motherboard

If you do get fan noises etc, but get BLINKING lights on laptop, assume possible fault with graphics chip, repost with details of blinking lights / colour and specific model of laptop

A fast blinking power light is an indication that the power supply is in a shorted condition. Parts called capacitors that filter the output power on the power supply board can fail and the power supply will short out causing the fast blinking power light. If you can solder then you can repair the monitor. Here is a link to a repair guide that has pictures and videos showing how to dis-assemble the unit and what to look for and replace to do the repair.

My samsung LCD monitor display blank but blue light is blink.


Hi,

Check to ensure all connections are in good place and are properly connected, if they are and yet no display, the picture board on your monitor is faulty, since the power light is on, it means the picture board of your monitor has developed fault.
take the monitor to a local repairer within your vicinity to help with the replacement of the picture board.

Actually, the ultra high voltage 'charger' for the florecence (a.k.a. your back light)has gone Kaput...

If your lucky, someone will have a monitor like yours that has the back light come on, but no picture (should get a similar blinking light situation, but a different code. Like... blink, hold, blink blink, hold, blink). In this situation (if your comfortable doing it) you can swipe the exciter from that monitor and put it in your monitor. Obviously this is a more economical way of repairing the monitor.

Just to be on the safe side (as the repair is blindingly easy. 6 screws, pop out, pop back in) DON'T touch any of the back side components. You WILL shock the supreme **** out of yourself. Between the heavy duty capacitors and the ultra high gain transformers on those things you could jump start a bus. So don't be fooled... those little transformers pack a mean sting.

Hope this helps...
