Sounds like an AGC [Automatic Gain Control] problem with its video IF stage circuit. Contact any service technician, or service center. This is not a user repairable fault.

The picture isn't very clear. What can I do?


If some channels are good but others are poor it is not the set. These sets are all much more critical for signal being good than the older sets--they will show noise etc a old set would not even show.

A dead give away is if DVD or Blu Ray etc looks great but TV channels do not---it is not the set.

Analog channels are fuzzy but the digital channels are clear


So what's wrong??? Analog signals that may seem pretty good on an old CRT would seem terrible on the newer TVs because all the flaws show up much sharper. Thank goodness for digital signals. With digital signals, unlike analog signals, you either get a good clear picture or no picture at all.

Hi,

Below are some troubleshooting tips for a TV that has a fuzzy or blurry picture;

If your Plasma or LCD TV picture is blurry or fuzzy there are several things that may be causing the problem. It's worth running through the following list before seeking service. You may find yourself saving the full cost of a TV repair.

Make sure you are using the appropriate cable box for your TV. If you have a high-definition TV you should also be using a high-def channel box from your cable provider. Watching standard definition channels on a high-def TV can make the picture look distorted and fuzzy.

Not all cable channels are broadcast in high-definition. When you stretch a standard definition picture to fill the full frame of your wide-screen TV it may look distorted. You can try changing your TV display settings to show standard-def channels at their native resolution. This will create black or gray bands on either side of your picture.

Ideally all of your video components will be connected to your TV with HDMI cables. Your next best option will be component video cables. If your cable box does not have HDMI capabilities, contact your cable company about upgrading your box to one that does include HDMI.

Make sure there is no glare on your TV from a window or other strong light source. This can significantly degrade the quality of the image you are watching.

If your TV has digital noise reduction, try turning that feature on.

You can adjust your TV's sharpness and picture modes to see if that improves picture quality.

Try plugging the power cord into a different electrical outlet and/or surge protector. You may be receiving electrical interference through your power cord.

Trying moving any nearby electrical devices away from the TV. They may be creating interference that can degrade the picture quality.

Let me know if the above helps or not, so that I can direct you further on what do next.....

Best regards.

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)

My vizio p4 edtv 46" made in 2003, went from working fine to a fuzzy blurry picture. You could change the channel and it would be fine for a second then back to fuzzy and blurry. I hooked my dvd player up...


This is not an easy fix. It's the main board (PCI) which is the board you plug your DVD player or cable line into. You could replace it yourself, but if your not a tech you might want to have a local repair shop do it. You could find the part online. This is an older TV so the part might cost you $300.

One channel fuzzy


Tis is an ongoing problem I seen increase alot over the past few months. From what I can gather, all the channels being broadcast over going from the analog to digital, there's no big suprise to anyone. However, the change from analog to digital is changing at a faster rate, so when you look at the TV some channels will be fine and others will have grey lines, fuzzy picture. The only solution-you need a TV with some kind of digital tuner. On the TV itself if the (TV has one) it will say "SD" or "ED" which stands for standard digital or enhanced digital.

Poor screen resolution and unable to get channel guide.


The channel guide is a service just like closed caption. Rumer has it that it's not going to be around for much longer. The only fix is to unplug set ..wait awhile till memory loss occurs...plug back up and do a setup. Nothing in the TV will cause partial guide. Weak signal could and cause fuzzy picture too. Complain to cable company. But brightness problem is something else.
