DVX 51cm tv issues.
Just got this in yesterday (dont have the model number on hand as I am
away from it at the moment.) Its about a year old, flat crt and yes basically chinese junk. However it fits perfectly in the hole in the wall at home. Problem: When you turn it on, a thick white raster in the middle of the screen flashes on and off at about 2 times per second nothing else is on screen, can hear eht come in and out with the flashing. After a few minutes the raster will litterally grow as you watch it and start flashing faster. After 6-7 minutes it will come straight on like normal except the picture at the bottom is scrunched up 1/3 of the screen and will gradually grow down until a full normal picture is displayed. Once running it will run flawlessly. Now I do more work on dvd players and audio equpment and rarely look at a television's, I got this with a whole lot of gear yesterday for $20, no surprise it wont work perfectly but when its warmed up the picture is damn good. When I get home I will try heating the powersupply/hv section with a hairdryer. Already gone over it for bulgy caps and cold solder but came up without much writing home about. Has anyone got some tips that I should try on here? Joe. |
