Saeco Philips coffee machine display screen doesn't light up?

I can still use it and I can barely see the options but display screen doesn't light up

I'm having it sent back for repairs, is there a quick fix for this issue so I do not have to send it back

Does it look like it is running with the exception of the screen being black?

Does it ever post anything on the screen when you hit the power button?

Beep tones and blinking lights tells thetechnicians what is going on with the laptop and why it is not booting. Most times it's a motherboard issue when you hear beeps or blinking lightscontinuous.

There may be problem in Monitor or VGA Card. When you Turn on PC the Monitor light is green after 10 second if It will be orange . It means your monitor is alright . but problem in you VGA Card. When the PC turn on there is any beep. If no beep then your RAM is alright. Problem in VGA Card.

• Have your ps3 in standby mode (red light).
• Now, press and hold the power button in the front down. Your ps3 will beep twice. Let it go almost exactly after you heard the second beep.
• Wait 10-15 seconds. A display will show up, and just answer yes to all!

try this

could be the whole pc is fried :(

I have had the same problem with my ps3. its simple, put your console on stand by. then hold the on button(on the console) down until you hear 3 beeps, then let go and hold again until you hear 2 beeps and 1 seperate beep. you should have some options displayed choose option 3 (restore system files). then just keep clicking ok. that should work!!!!!!

3 short beeps means Base 64K RAM failure.

try to replace the RAM.

Read this very carefully. Turn off your ps3 from the back. Then turn it back on wait unit the light is red. Turn on the system through the front keep holding the power on. You will hear a beep one time that just tell you that the ps3 is powering on keep holding the button until you hear the second beep this will rest your video setting. If that dosnt work call me at sony

Actually you do want to hear one beep.
This is POST. Power On Self Test.
No display is a video problem. Swap the card for a known good video card. You should be able to get into the BIOS with that. Presario’s are quit.
While in the BIOS see if the HDD is shown. It doesn’t hurt to check the connection inside. Please keep yourself grounded when inside the PC. For the Compaq Presario S4020WM site go here:
