Tries unplug the tv and the cable box about an hour,replug both back in.The cable box,will upgraded it software and the tv will reset itself back to factory setting.Every things should work now.Not,than the tv Tuner board,it dead,that board,that take in the incommimg broscasting signal cable to the tv.

Hello. When the screen goes blue it means that you have lost your signal from the cable or the satellite. It could be the cable which connects the tv to the signal supply source, the cable box or the satellite box. I recommend that you replace that cable.

If it continues call your cable or satellite provider and tell them what is happening as it could lie in their equipment, and not yours. Joe

I'm not sure what you mean by "cable box is on or off". Do you mean connected? If the cable box is connected to the TV through a 300-ohm antenna input, you are probably getting a lot of interference from the workings of the cable box. Try moving the cable box away from the TV.
If the TV is connected to the cable box with a 75-ohm cable, it may not be properly grounded - try another cable.
Also try manually tuning the channel on which the cable signal comes in, usually 3 or 4. Try an alternate channel.

If the DVD player is built into the set, the signal is less subject to outside interference. If the DVD player connects to RCA jacks on the set, it is also less subject to interference.
Vertical hold problems can be caused by aging capacitors in the "sweep" circuits but usually one sees that as loss of vertical hold on the DVD signal, as well.
Good luck.

why hdmi input wont show up

first thing I would do is to make sure your cable box is turned on. if not fixed, make sure you have the correct input. this can be done by viewing all the inputs that the tv has by pressing the input button on your remote until you find a picture. if it is still not working, make sure you have you cable run right. there should be one cable running to the cable box and into the port labeled antenna or input, then anouther labed cable running from the output port to the tv. there might also be a vcr or dvd play inbetween. if that is the case, the cabel running from the cable box should go to the input of the vcr or dvd play and the output line should go to the tv. any equipment inbetween the cable box and tv should be turned on when viewing you cabel tv. you will also have to make sure that any equipment inbetween is running off the cabel input.

hi my name is mark, since you have a cable box. you need to switch the tv back to the analog signal on the tv through setup or menu screen. then use cable remote to change channals. thanks for your question.

This is a problem i fix daily unfortunately there isnt anything you can do its either the box or the signal...more than likely its the signal and can only be fixed by your cable company but most cable companies do offer free service calls...hope i was some hep

it wont hurt to run both to the set, they wont interfere with each other
