Fuzzy picture purchased from a neighbor today. picture is fuzzy with horizontal lines. we are using Motorolla HD converter box with a powered internal antenna (works great with our other TVs).

any tv 30 yrs old is surely analog , these wont work in todays environment as the ole government did away with all those analog goodies , you'll need a converter to convert the new 1080P HD pictures down to the fuzzy analog signal so your tv can see them , unless its a family heirloom with a fantastic looking wooden cabinet id be looking to get a new HD tv to replace it

This is a older model and likely the first generation of HD set made by Mitsubishi---where the HD input is on rear (DTV?) ARE THERE TWO JACKS MARKED H sync and V sync?

If they are there set needed an external box made only by Mitsubishi for for later HD use.

USUALLY THIS PROBLEM IS CAUSED BY A DEFECTIVE X OR Y SUSTAIN BOARD. ESTIMATE BETWEEN $300- $700

it is important to understand the difference in digital cable and high def. high definision is on a fiber optic display alwing milions of pixels per square inch on your tv. the resolution effects your fuzzy picture you are recieving . the only real way to fix that fuzzy dull picture is to get a HD box from your cable provider and an HDMI cable to conect it to your HD TV. this is the only connection you will need for picture and top line sound. In the end the fee is usually $9.95 or less a month and it is well worth the difference in quality of TV viewing.

If the picture is clear when using a DVD and remains "fuzzy" only with cable, then either the cable is bad or the up-conmvert from standard def to Hidef is creating the "fuzz". Depending upon the method used by the set to perform the "up-convert", the noise you are seeing may be normal.

you might have an overheating problem- make sure you have adequate ventilation around your tv

Good Day;

Keep talking to the factory, it is their product. Best Buy won't replace unless it is deemed not repairable and/or terms of the contract. You purchased the extra warranty because you most have felt that the TV might break down. Well, it did, now use the contract to repair your TV.

Good Luck, big IRISH.

Greetings blueberrie,

Many times the cables that you are using can contribute to picture quality. You will want to utilize the best connection possible, in most cases HDMI or component cables. Also, you may want to invest in a line filter, sometimes known as a surge protector. Many of these items are able to control the inconsistencies in power your unit receives, giving you clean power, which will influence picture quality.

I hope this helps!

Well, I can tell you it shouldnt have anything to do with your not having an HD box. The TV does not require a HD signal to give you a quality picture. The HD box only gives you the enhanced HD signal, but should work as any regular TV without it. How do you have it connected?

unit needs a control box inorder to operate
