If your connected to a computer, then this means that the computer's resolution is greater than the supported resolution on the TV. Try reducing the resolution on your computer, and reconnecting it to the TV.

If your connected to a cable or satalite box, there should be a "resolution" button on the box. Change this to a lower (or higher) resoulution.

If none of these work, try changing the TV input. This may be a simple but common mistake. Also, if required, make sure your TV channel (not cable or satalite) is on the default channel (usualy 03).

If it still doesn't work, contact GE and tell them the problem. If anything, they can help fix it. If it is still under warrenty, they can have a repair person come to your house and fix the TV.

Good luck!

Screen stays blue and wont show the picture


TV may be on the wrong input and that will give you a blue screen. When you turn the TV on and the screen starts lighting up it should show on the screen what input the tv is on. If it is not on correct input change input with the TV remote or buttons on the tv. If it is on the correct input try a power cycle on the cable box, just unplug the cable box power cord for a few seconds and then plug it back in. If neither of these solve the problem describe how the cable box is connected to the tv.

Having trouble turning my Tv on,have to turn it on and off/plug and unplug for a while to get pic and sound.Can you help?


Good day!

The problem of your TV could be the power supply.

Please follow this steps on how to fix that problem
:

  1. Remove the back cover of your TV.
  2. Try to look at the power supply board (it usually directly connected to the power cord)
  3. Plug-in your TV and power it ON to perform a voltage data.
  4. Check the input voltage of the power supply.It should have 110vac or 220vac it depends the input voltage of your TV that comes on the outlet.Use multimeter tester (range in AC)
  5. If the input voltage of the power supply doesn't have a reading,the power cord is defective you need to replace it.
  6. If the input of the power supply have 110vac or 220vac.Please check the output voltage of the power supply using your multimeter tester (range in DC).Normally it should have 5vdc for the system board,12vdc for the audio system and 24vdc for the inverter board (back-light).Also look for the leak/bulged on the top capacitor.If any replace it with the same type,ratings and value.
  7. If the you have done all procedures above and you have found any defects and the output voltage are complete.The problem could be the the system board or main board of your TV.This is not for D.I.Y because the parts are surface mount and its very sensitive.If the problem is main board you have to replaced it,buy a new main board its available at the market.
  8. When the output voltage of the power supply doesn't have reading,please check the following
  • Fuse---look if it is busted
  • Power transistor----If it is shorted (range in diode test)
  • Resistor----If it is open or change value (range in ohms)
If you found any defective parts replaced it with the same type,ratings and value.


I hope this solution will be helpful.Thank you and good luck.

I have a Proview LCD TV model # PA-32JK1A. When I plug in the TV, the orange standby light comes on like usual. When I turn on the TV (with the remote or the front panel) the blue power light will come...


Hi, I just read what you have posted on my LCD TV troubleshooting guide, it does not sound like bad T-CON board because you do not get the sound, you disconnected the main T-CON connector from the main board and get the glowing screen but you still do not hae sound.
In the LCD TV, you can discoonect the backlights inverter board power cables (cables from power supply to the backlights inverter board), and the T-CON board cables from the the main board to the T-CON, you should still get the sound since there are no feedback singals from the T-CON or from the backlights inverter boards to tell the main board that they are bad or not.
If you are 100% sure that you do not have sound on all the input modes then I would suspect the main board problem.
At least the backlights ineverter is good.
Do you get the 12v at the T-CON board surface mounted fuse?

LG Television 37LB4D "Rebooting"


Ours is crapping out just like yours. Picture goes out, "black and white squiggles" appear in the top left of the screen then TV input appears, then it either repeats or gives me my picture back. This happens with both the HDMI slots (tested all 3) and both Component slots. Seems like the bulb or a circuit board on the TV is faulty. What a piece of ****, never spending another dime on LG products. I did get it to come back by hitting the back of the TV with a good slap, but it gets really annoying.

Blue screen - no signal - turns off [visio tv L42hdtv10a]


With out turning on the T.V., Push the [Input] button on the remote control. The TV should turn on and activate the input menu, just continue to push [Input] until it is set on TV (or HDMI, etc.). this should solve your problem.

Plasma tv screen goes black once you turn it on. Only sound


I have a panasonic TH-42PX60U plasma TV. When I watch TV programing I have no problems, or with the DVD input. But if I switch to another input, be it video game (PS2) or vcr the screen sometimes goes black and the red power lcd light next to the power switch flashes. Holding the power button in for a few seconds will shut down the tv. Then I can turn it back on and it may operate normally again for a undetermined period of time, before the screen goes black again. This never happened when new. The tv is about 1 year old. Any ideas on this problem? Thanks Ernie

T.v. will not stay on


Power on your TV and press the INPUT button on the side of the TV repeatedly and rapidly until you can change it to a different input, such as AV.

If this does not work. Try this: With the TV off, press and hold the input button on the side of the TV for about 5 seconds. The TV should power on and the input list will appear. Let me know if either of these work.
