I have Farenheit T-7013HRS screens in my car. When I connect them to a 12V power supply, I get no response. I have the remote control, and I have them hooked up to a farenheit dvd player. How can I test the screens to make sure that they work? Is there a fuse in the screen that may be blown?

ok let me think a little about this, the reason the control box has wires to connect to the thermostat is because some how the power has to run through the thermostat so it can be controlled by it. as you know the thermostat is nothing more than a switch that gets activated by temperature. now lets figure this out. you say the box has only 3 wires, but in your description you mentioned 4. how many is in total?
you should not have to run a double wire to the thermostat and the power supply. you should be able to come from the power supply and wire the supply and then the other to the t-stat but do get a second opinion. watch the color coded wires though manufacturers changed them to confuse the d i y er
If you have a black screen with a blinking DOS/text-mode cursor, and you're sure you disabled the integrated graphics, the card is bad or your power supply is not delivering enough electricity on the 12v line to start up the graphics card BIOS.
To check if it's your power supply, simply disconnect your DVD and hard drive from power, and your video card will have enough 12v juice. (the GT610 needs more than half of the power on the 12v line that the stockPavilion P6-2330 can supply). If disconnecting your drives fixes your issue, you will need to buy a better power supply to use them at the same time. One with 15-20A on the 12v line is ideal, a good price is $50 or less.
If it still doesn't display anything besides a blinking text cursor when your drives aren't connected, try re-seating the graphics card and make sure all the pins are completely connected, if this doesn't solve your issue, the video card is most likely bad, just exchange it.
If you have a black screen with a mouse, your new card is probably being used as a 2nd desktop. To confirm, just connect your monitor to your integrated graphics; if you get a picture, just set your new card to be the primary desktop.
NO NO NO... PC power supplies are switching supply's. The transformers use high voltage to drive other components. Increasing the power out of the supply will require you to upgrade the power supply to a higher wattage output.

that problem is very common on a viewsonic tv.you need to open the back cover of your tv by removing the four screw.you can immediately see the power supply of your tv after the cover is remove..It is a small pc board where the ac power cord is connected..First using a multitester measure the output voltage of the power supply.the output must be 5v for cpu,12v for sound and 24v for the inverter board.this inverter board is the one responsible for illuminating the screen of your tv...if the output are complete,,replace the converter board..if one voltage output of the power supply is missing replace the power supply board...g
good luck!hope i help you... please vote for my help tnx..
You can connect the splitter to any of the 4 connectors that power IDEs(Hard Disk, DVD ROM, CDROM etc.,). The splitter's sole purpose is to split one 12v supply into two 12V power supplies so that we can connect two devices instead of one. You can disconnect the power from DVD connect the splitter to it and then use one of the two 12v supplies from the splitter to connect to the DVD drive and the other to the HDD fan.
