I have green and red spots on my tv and seems like more and mores spots are coming...what is wrong?

Check your cables on the back of the TV and cable box. You either have it connected wrong, or they are loose. If you are using red green and blue, make sure that you are tightly in the red green and blue connectors. If you are using yellow white and red, then make sure you don't have the yellow in the green spot.

It sounds that the main digital board has damaged. 12 blinks indicates it. if you wish to know more check this link for more details about 12 blinks to Emerson TVs

dust will not cause an issue like this in this type of set--RCA? it means a short of some type exists and the set shuts down or blanks the tubes--all you have described as far as appearance is normal.

RCA sets like this can be difficult to repair and also if you Google the model number you will see they have a lot of "problems".

sounds like you hooked up red wires wrong

make sure red wire of component video is really in the video spot

make sure the red wire for audio is really in the audio spot

it souns like these are attached wrong or backwards

this is very common mistake so take some time and make sure they are in the correct spots

if this doesnt help give me more details and i can try to help more - pictures might help too

good luck

You could have one three component cables (red, blue, green) not put in the right spot on the back of the TV.

If you are not using a component cable, then the problem can be either the Main board and or the Time Control board.

Try using a different input on the back of the TV, or even using a different device into the back of the TV. This will tell you if the problem is with that one input on the back of the TV or if the problem is with the TV itself.

PANASONIC..PT-52LCX15. STARTED TO A LIGHT COMES ON THE SCREEN. THEN TWO LIGHTS. FINALLY TV DONT COMES ON. I PUT ON THE TV, AND ON BOTTON START BLINKING AND TV DONT COME ON..I TAKE OUT THE TV LAMP..IT LOOKS GOOD NOT BURN. SHOULD I REPLACE IT??

I had red and green spots, and I called the service department at the furniture store where we purchased our 42" TV. They said it needed to be updated, and they picked it up, fixed it, and delivered it back to the house for about $25.00. We had a warranty, so it only cost for coming to the house twice... No more spots!

Could you show a picture of the distended cover you mentioned?

 

Were the light blue lines you were referring to, diagonal, or truly horizontal?

Sounds like CCD sensor problem . It starts with 'noisy' pictures ( colors not true and resolution deteriorates )but eventually the sensor stops outputting anything and you end up with blank screen. Have the sensor replaced and camera will work fine.

is there a speaker from a stereo player near the set? i noticed mine give my tv a greenish tint on the side of the tv closet to the speaker
