I suspect that your supply has gone bad. You will need to find the service manual for voltage measurements. If you want to get replacement boards many can be found on ebay or you can check www.shopjimmy.com they stock boards for many units and I have had no problems.

SOURCE: 50 " Phillips Plasma tv. Screen is black, blinking red light.

Sounds more like blown/exploding capacitors on the PSB-Power Supply board. No OSD-on screen display a blinking led or chatter/relay clikcing at startup is the tv going into fault protection and bypassing the startup pins. The YSUS-Main controls the pic which is attached to 2 buffer boards the YBU-upper YBL-Lower. They control the upper and lower portion of the OSD and the YSUS controls both of them. Since you're getting No OSD you need to check for blown caps on the PSB first. Unplugging the set resets the error again. So you start all over again.

I have a Samsung 40" LED tv that has sound but no picture. You can see an image if you shine a flashlight on the screen. I see no backlights when I take off the back.


Hi!

Check the backlight circuit, but first, check the power supply of the blacklight circuit, does it feed the backlight circuit or not. If not, it's the power supply circuit, if yes, check the backlight circuit itself, and if it works, check the backlight themselves, the led. Good luck,


Serge.

My laptop ( sony viao laptop) fell and now once turned on I have a black screen all lights and sounds are good. Could this be a led disconnect problem or a video card situation. What type of video card...


Unlikely to be a vga cable loose, but you can check by removing the switch panel cover and the screen to check it is still firmly housed.

test the laptop first in an external monitor, if you get an image, then the graphics chip is still ok

This then points to the screen, may appear undamaged, closer inspection with a torch, shone through the back of it will show any cracks you do not see straight away.

If the screen will not light up, fault is probably with a damaged backlight or inverter, you are then looking at a new (or 2nd hand) screen

Blue blinking light


The monitor is probably on protection.

To start unplug monitor from power and from computer and test computer with different monitor to find out if it is monitor or computer fault.

If it is computer fault and no video signal , then test:

  • Video cable.
  • Video adapter on PC (sometimes integrated on motherboard)
  • Motherboard.

If it is monitor fault , then the monitor is on protection.

When on protection you keep having a flashing led on front of the monitor , and monitor turning off by itself after a while, that indicates a fault condition.

The flashing light indicates a diagnostic state called protection.
When the Monitor goes on protection there are only two possible causes.

1The internal circuits are jammed because of electrostatic charges accumulating on capacitors, or because of a wrong voltage read by the main chip on your monitor controller board. this started the protection circuit.

2 The protection circuit detected a wrong voltage or a broken contact, identified an internal fault and kicked in , starting the flashing light.


If you are in situation one, then the monitor will reset just unplugging power cord for one or two hours,sometimes even minutes.

If you are in situation 2 , then there is an internal fault.

Common faults that can occurr are a blown capacitor on power board, faulty inverter board, faulty input board, or a fault on LCD Digital Controller board.

Check also the video cable or any external connection cable, if the cable is shorting, or the connector is bad, you can get same flashing statebecause of the video cable.

Try moving the video cable, and if the cable is not built in, then also try a replacement cable.

If under warranty contact the manufacturer ringing the number on the user manual

If you want to repair at your own expenses, just locate any good qualified repairer.
