Question about Mitsubishi Diamond Plus 73 17" CRT Monitor
I have a mitsubishi Diamon plus 73. About 5-6 years old Last night when i turned it on the image on the screen was shrunk. Although the width was approximately the same ( albeit bulging down the sides) its height had shrunk from both the upper and lower edges. another way to describe this is that it almost appeared wide screen with large black bars at the top and the bottom. None of the image was lost it was just squashed into this space i was considering opening up the case myself to have a look for a loose wire or something. I hav efound that if i place my hand on top of the monitor and wiggle the screen returns to normal. I have tried wiggle the 2 cables at the back of the monitor but they dont really seem to be the cause. So perhaps there is a component situated above the tube and between the case? Any tips on what to look for? PLus any tips on how to open the case as there dont appear to be any screws? amd i dont want to damage it. Thanks
Well first af all ,you never find this "loose wire" because it is a mith. what you have is a "cold solder" in the vertical IC, if you have a solder iron , and the ability to open it (without scratching), and then take off all the shields (without cutting your fingers), and get the solder area (without breaking the Tube). at this time ,it take you 1 minute to solve...!!! iF not... leave it to the repairman!!!.
