Color comes in and out

It takes like 10 minutes for the color to come on the tv i usually put it on the video 1 channel because the picture comes in right away when my ps2 is attached well black and white but it warms up and the color comes in after about 10 minutes if its on the cable channel the screen stays blue and recently it seems like everytime the program is a little dark the color will go away and all i have is black and white and will come back sometimes when the program has a brighter picture i looked at the cable connection in the back and it is fine i tried wiggling it to see if the picture would come back but it wouldnt i dont think its a cable issue but i really could use your help thank you.

I have dish network and I just received a new remote I was able to program the remote and can see the channels for dishnetwork but somehow the channel that my tv is set on to receive the signal has been...


Hopefully after 3 months this has been resolved, but if not, here are some simple steps to take. If you are in TV1, where the receiver box is, you want your tv set to channel 3 or 4. Depending on the cables you have, you may need to put your tv on an input. Usually Video 1 or 2. If you are at TV2, the location away from the receiver, you will want your tv on channel 60 or 73. If neither of these work, try to unplug the receiver from the power source for about 10 seconds. Hope this info helps.

My screen on my nes is blurry how can i fix that


If your screen shows a blurry image it can be a few possible things (and only these things).

1. The first and most obivous problem is being on the wrong channel - for example, if you are on Channel 3, but the switch on the back of your system is set to channel 4, you'll see a VERY fuzzy picture; simple switch to the other channel and it will come in clear.

2. Now...assuming you are on the correct channel, does your television receive other pictures clearly (for example if you change to a normal broadcasting station and it is still blurry, then it is a problem with your TV and not your NES system). Another way to test is to simply switch TVs and see if the same picture problem occurs.

If 1 and 2 are not the problem, them we know the problem is with your NES system and this should be an easy fix.

If you are using an RF Switch, then it is most likely the pin on either end of the switch has become bent (or was bent and now is bent back) and will no longer give a clear picture. The easiest way to test this is find a set of AV cables (any av cables - these are the red, white, and yellow cables that often hook DVD players to television). Find a set and just take one of those ends and connect it to the side of the NES system into the circle that says VIDEO and take the other end of that same color and put it into your TV into the circle that says VIDEO (note that the colors don't always match up on the newer TVs, just make sure that if you are using the yellow end of the AV cable and plug it into the video on the NES that you plug the other yellow end of the av cable into whatever color on the TV says VIDEO! Then change your tv to the cannel for that AV slot (usually AV 1 or INPUT 1). Turn the nintendo back on and see if the picture comes through clearly - if it does, it means you had a bad RF switch and you can either get a new one, or just use AV cables instead!

One of the above problems IS the problem - I've repaired over 1000 NES systems and 95% of the time it's just a bad RF switch (so the AV cable test works best)

Problem w/brand new 42" Insignia Flatscreen TV


if it's still under warranty- get it replaced!! while you can!
shouldn't be doing this! at least until warranty runs out- you know how that goes!!
if it was quite expensive- might try for extended warranty- if not too outrageous!
good luck!

No Picture -- just a black screen on my vizio vx37L


Did you hear any pops before the screen went black?
You've tried completely discharging it? Disconnect everything off the TV, all cables and power.
Press and hold the power button on the TV for at least 20 seconds.
Let it sit, and in about an hour, plug just the power in (directly to the wall) and see if it comes on. There should be an indicator light, is it white or orange now? Was it a different color before?
Odds are it's a board, be it the main or a video, don't know for sure. If you can take the back of the TV off and see if there are any evident signs of damage, blown or swollen capacitors, burnt traces or resistors/diodes, etc.

Take time to get used to the settings, you may think the screen looks dull at first. The truth is most people have way too much contrast on their TVs.
These settings will also work for Cable or Dish hookups, in which case you may change the Noise Reduction option to Medium to reduce signal noise.

Dark colors Picture going out


It is hooked up to Direct TV. When I change the channel on the TV to another input it looks fine but without a picture. as you do not see tint in another channel means your color section is ok it is due to video or luminance section.

Cannot view channels higher than 10 and cannot get DVD to come on


Dear althea, I cannot help you with the first problem, but as for the second, "DVD does not come On" and "Do not understand Video 1, 2, & 3 settings." it is very simple. YourTV has the sockets at the front Marked Video 1, Audio L and audio R, The y are in three colors - Yellow for video, red for audio right and White for Audio Left. Similarly, you have 2 such sets of 3 sockets - they are Video 2 and Video 3. This allows your TV to be connectod to three different Video sources - maybe a VCR, A Video game, and a DVD player. To view the pictures generated by your DVD Player, all you gotts do is connect the supplied AV cord from the rear of the DVD player to the front three sockets in the proper order - Video from DVD to Video of TV, Audio L & R from DVD player to Audio L & R of TV. Now press Video on the TVs remote. Press repeatedly till you get Video 1 displayed on the screen. Then, if you now play your DVD player - make sure there is a disc in it - you will be able to view the picture / movie. Good Luck
