Bad computer monitor...

Hi,I'm working on a monitor for a friend of mine, she said that it smelled like burning plastic for three days before it went bad.The monitor:"Proview model: 786N""Product no: PS720F-1s""Product series: DZ-777NS"When you first turn it in the relays click like they are supposed to, after a moment or two the little "Check signal" window pops up, but it is scrunched on the left side and spread way apart on the right side. The screen looks normal otherwise.At least this is what I thought until I opened the case the turned the brightness up, the vertical appears to be fine, but the horizontal stops about three inches from both sides of the screen.My first thought in this is that the horizontal section is not getting enough voltage, if I turn the brightness all the way up the picture shrinks inward even more (although it does get brighter). I posted a picture online if you want to look at this: One other thing is that the buttons on the front will not active the geometric adjustment menus but they will bring it out of "sleep" mode.Nothing appears to be burnt of fried on either side of the circuit board, I'm not sure where to start with this thing, any suggestions?-Landon

Sounds like the ever famous Safety cap is leaking, I can't remember thecaps number but it is the same as the hot Exam. if the hot is a Q404 then the cap is a C404 those numbers are just exambles

Repair kit part no TD772 will cure this problem. Do a search on YAHOO for 'monitor repair kit TD772' (without quotes) unless you have fixed it already.

Hi,

So, your repair kit is able to fix bad solder joints, had you read my previous posting you would have known this.

Just a suggestion next time.
