My defeway has been working good for the past 2 years until about 2 weeks ago it started blacking out all 4 cameras I can't find my manual any way to fix my black screen cameras or find manual

SOURCE: Sony TRV-19 Camcorder - Black screen in camera mode

Fixed it, at least temporarily I had the side off my trv250 examining it, especially the CCD connection. I had read the post about soldering a capacitor to pins 1 and 3 (from the left) on the bottom row. I didn't have the specific capacitor on hand, but I started touching some of the small ones I did have to those pins. I found that after I touched a 100uF, 10V cap to pins 1 and 3 the picture suddenly came back to life and stayed that way after removing the cap. I have no idea how long this will last, and I've set up the cam on a tripod in the livingroom with the LCD display facing me so I can monitor it. If you, like me, figure you have nothing else to lose, you might want to give this a try. Note: my camera was suffering from the green smeary horizontal lines problem, and wasn't completely black. I'm not sure if this makes a difference or not.

SOURCE: ViewSonic 19" flat screen monitor goes black - intermittently

Hi,
There could be a problem with your display card settings or the display card itself. If you are using Windows operating system, make sure that you have the monitor driver installed for that specific monitor. This is to ensure that Windows only allows settings for which your particular monitor was designed.
Let me know if I can assist you any further regarding this.
Best wishes,

SOURCE: my 42" plasma tv screen went black but there is still audo

The most likely the TV has a power supply related problem. The most common thing to go out is the circuit board that supply power to the screen. Commonly called a Backlight Inverter Board.
I can't say it's 100% the problem because I can't actually look at the tv over the internet.
If by chance the TV is still under warranty, go that route.
If not under warranty and If you have some electronic experience, you can purchase a Service Manual over the internet and diagnose the source of the problem and fix it by soldering in the new part. The Service Manual will give you circuit diagrams, test points, and part# lists. Usually, cost under $20.

I hope I shed some light on the subject for you.

SOURCE: LCD Screen went black!!!

hi..

I had the same problem. The flex cable for backlight was broken. I take out the backlight LED module. There have one resister along with 4 LED. I soldered two wires (AWG 30) onto two sides of resistor. Just follow the trace of flex cable and then solder the wires to the pins of connector directly. Although there have 4 wire on the backlight cable, it only need two to work. In order to avoid any finger print and dust fall on to the LCD, it would better wear a hat and plastic glove during this operation.

thank u

SOURCE: natural gas generator will not start. 4 years after installation.

very likely a fuel problem. First pull the air cleaner cover off and try choking the engine by putting your hand over the intake partially choking it. If this don't work then go Down on the bottom right hand side behind the battery you will see a fuel regulator on top of it is a fuel solenoid with 2 wires coming off it. Below the fuel solenoid you will see 2 -1/4" pipe plugs one on top of the other. If you pull the top one out and gas comes out then you have fuel up to the solenoid. If you pull the bottom one out and crank the engine then you should get gas out of the bottom one. If you don't then make sure you are getting 12 vdc to those 2 wires during cranking. If you do then You are going to have to pull the 4 screws out of the solenoid and pull the solenoid off and make sure you the seat on your solenoid valve is not sticking. If all this checks out and you are getting fuel out both 1/4" pipe plug holes, then you will need to see if you have a spark at the spark plugs, if you don't then something is shorting out your ignition coils. Disconnect wire 18 from its terminal located above the oil cooler. If the engine starts and runs with this wire disconnected then you need to trace this wire back to the control panel and see whats causing it to ground out.

Let me know if this helps.
