Tv wiggs out with too much black

I don't know what model you have but common connections are:
for higher quality video use red, blue, green in video section on receiver and TV and white and red in audio section
for lower quality video yellow in video section and red and white in audio section
that will allow you to watch programs from receiver on tv. As for antenna to depends on model of your unit and if you use or nor antenna on the roof you may be able to receive over the air programs. That connection is not regret for sat only programs

Back light problem. Check and replace damaged components at the back light inverter section circuit. With most models of modern LED type TVs, this circuit section will be a built in part of its main power supply regulator board.

The power supply module inside TV is damaged. Without proper knowledge and instruments, better call service company.

Sounds like poor reception - check your aerial connection

Common failures in the LCD monitors are due to bad DC filter caps in the power supply section, that will be the first place to check.

Hello divalisaf,

These are a few things I want you to check first.

1) Make sure the cable set top box is on and the cable is connected to the TV properly (This may seem simple but I have had to charge many people a $60.00 service fee plus a $70.00 travel fee just to turn on a cable set top box)

2) Make sure the TV is set to the proper input you are using (RF( F connector) , HDMI, Component video, and or Composite Video)

3) Make sure the TV is set to the proper channel (either channel 3 or channel 4 depending on your area) The cable set top box should be action as your tuner.

If all of these conditions are met, then we can begin troubleshooting.

First determine if the other inputs work (HDMI, Component video (RGB), Composite video (yellow), s-Video (6 pronged black cable).
If the inputs work then you possibly have a tuner problem
If the inputs don't work then then problem is likely in the video microprocessor.

If the problem is in the tuner or the connective circuitry then we will have to determine where to get a replacement tuner (or you can just use one of your other video inputs)

If the problem is in the video section (which includes the microprocessor) we are going to have to troubleshoot the video section which will involve you having a background in electronics, if not I would suggest having a qualified TV technician perform service on this TV.

I hope this helps,

Thank you,

Basic repair for skilled TV repairman = solder connections on
vertical output IC.........Can be done in home.....T.

It worked fine yesterday. Sound on all channels. Sometimes the picture goes black on channel 6. We can get it back by going up one channel, then back to 6. it is due to cable signal ie weak. now there is no sound this is due to sound section 1 loose connect in sound section 2 speaker 3 problem in sound section some part must have failed.

There some thing that you had done to get black and white on your tv with the dvd ,check your connections.if the connections are properly connected then the tv could be having a problem in the video input, have a tech look at it.
