Is My Daewoo TV Dead....Green Picture
Hello. I bought a 25" (I think) Daewoo TV last fall at Target. Up until tonight
it has been a great TV for the money. The TV was working great. The TV and seperate VCR were both on. The TV was fine. I pressed play to watch a video and when the tape started to play the picture was lime green. At first I thought I had gotten ahold of a old VHS so I turned the VCR off. TV picture was still lime green. I checked the color and tint settings......right where I have had them all along. Back to the picture. Most things were green....sky on a commercial was pink. TV still worked great...good sound..remote functions on the TV screen were still showing up in blue...like they should. I turned the color all the way down to a B/W setting so I could watch without going blind. Even with color turned all the way down to just a B/W type picture there is a pink haze in the left corners and a green haze in the right corners. The TV is only about 8-9 months old. Yes it is on 12-15 hours a day....but shouldnt this TV last longer than this? Any easy fixes or is this now just a B/W set? Thanks Greg |

Is My Daewoo TV Dead....Green Picture
"Jerry Greenberg" wrote in message om... The fault may be in the video drive or bias circuits to the CRT, or the CRT itself may have failed. This can be properly checked by the technician by taking the bias voltage readings at the CRT elements, and by checking the video waveform levels driving the CRT. If the set is less than a year old, I would assume it is still under warranty. You should take it back to the dealer with your proof of purchase. These sets will usually last about 20,000 to 30,000 hours before failure. This should be about 4 to 5 years with average use. As the original poster mentions what appears to be purity errors in the corners of the screen (which could well be doming) could it be that somehow the tube has become severely magnetised? I've seen some really bad effects caused through a faulty degaussing posistor, which can produce symptoms varying from reversed colours to a total loss of one colour.

The first three sentences into this guy's post, it hit me - degausser circuit's gone AWOL. In my case about 6 years ago a fine 20" Samsung of mine got a green/orange tinge to the upper LH corner-the same corner of the set to hit the floor when the FREAKIN' AV SHELF COLLAPSED! Put the degausser in that corner pretty much outta business. -CC PS and don't even ask me just how that shelf collapsed! :P _________________ So, how exactly did the shelf collapse? |
