Hello Torr276,
Sound like you have either a bad LCD panel or a bad Back light inverter. The first thing is to start with the back light inverter. Its much cheaper. Replacing the inverter normally fixes 88% of all set with that type of a problem. You can request this part from www.interactiverepair.com

Best regards

Samsung aqua jet washer will not power on


please see this steps and fix it. God bless you

Drained/dead battery

Plug your iPhone into your computer or wall adapter to charge. If it does not charge when connected to either of these, you probably have a dead battery. The battery will need to be replaced with a new one.

Bad display

It is possible that it appears nothing is happening because the display is bad. If the iPhone sounds like it is working properly but nothing is visible, it is possible the display is bad and must be replaced. Unfortunately, the LCD and glass panel are fused together, and must be replaced as one unit.

Bad logic board

If nothing else works, your logic board is probably bad and needs to be replaced.

Flatron W1943 sb monitor goes into power-saving mode. Does not display data.


If the monitor is displaying the "Power Saving Mode" signal to the monitor, then the monitors internal VGA board is functioning, so you can rule out a broken monitor. However I have seen monitors blow the internal fuse to the VGA board which causes a false "SLEEP" signal. If this be the case then it will require replacement of the fuse (usually a microfuse soldered onto monitor internal board) or most likely a monitor replacement.

To test:

Option A: you can connect another monitor to the monitor output on the back of the computer and see if you get a display. If this monitor goes to sleep, then it is likely that your Video card is malfunctioning. If you get a display, then it is definately the monitor.

Option B: If you have another computer, you can attempt to connect the monitor to another computer. Also most modern laptops will be equipped with monitor output, so if you have one you can check it. If the monitor sleeps, then it is definately the monitor. If you get a display, then it is definately the computer video card.

Hope that helps,

G

I have power to the receiver but i have no display any ideas would be greatly appreciated


Since there is power to the receiver, you will have to open the set and trace from the main pcb. see if the smps circuit ( main Power) gives the required voltages to the processor boards. You will have to use a multimeter for checking the +5 to the micro processor, the display voltages, the cord to the display, the display drive. only a though test on these units will you be able to arrive at the issue. If there is no response, you will need to replace the main board. hope this helps for a decision. Good day

Screen on my compact laptop went black and I can only turn it on but have nothing but black


If the laptop comes on normally otherwise and is booting to Windows (you hear the normal startup sounds), look closely at the display and see if you can make out a faint image. It often helps to shine a flashlight on the display.

If the display is faint but present, you probably have a bad inverter board in the display. The inverter provides power for the display's backlight, and without the light the display still works but you can't see it. Inverter boards are available for most brands, they're not usually very expensive, and changing one isn't too difficult. A Web search for your brand and model and "replacement inverter" should turn up several sources. There are also YouTube videos showing how to replace the inverter in many kinds of laptops.

It's also possible the backlight itself is bad. If so, replacing the display is usually preferable to trying to replace the light. The light is built into the display and it's very difficult to replace without damaging the part or the display in the process. The display can be expensive, though.

If you're not sure that the computer is working, try starting it with an external monitor connected. If there's no display then, there's something wrong with the system board that's preventing the machine from starting up. Get that fixed, and it will probably fix the display trouble as well.

I have 2 cf-73scvtsbm one powers on but no display the other i believe to have a fried mother board


Can you make one out of the two? Perhaps you could take the screen of the "Fried MB" and put that on the "No Display"? get yourself a service manual first.

Rt2280 no power up, no display, standby light works


Might be the relay on the power board that stands up just behind the big transformer. I has a complete no power also, I shorted out the relay legs on the black one, it started to work again. I will probably replace it, since the problem started by the system shutting off randomly.
