Hi

Thanks for using FixYa. The issue is with the failed convergence (STK) ICs which needs to be replaced. It's not a difficult job if you want to do this yourself, you should require some basic knowledge about soldering-resoldering components. To start with you'll have to open the back of the unit and then replace the ICs (STK ICs) which are located behind the black heat sink and also check the resistors as if they are short the ICs might blow again after sometime.
Please accept the solution if the issue is resolved or post a comment for further assistance.


Thanks

Rylee

Wide screen monitor distortion
Depending upon the screen resolution that has been set in Display, the image will be distorted on these large wide screen monitors.
To correct this distortion.
1. Create a large circle image using a draw program such as Paint (hold down the Shift key as you create the circle as it will draw a perfect circle).
2. Open Control Panel - Display - Settings tab and adjust the Screen resolution slider, increase or decrease the screen resolution then bring the circle image to the front and check the image, if the circle is still distorted then change the screen resolution and check the circle again until you are satisfied with the image of the circle.
3. When you are satisfied then click apply.

Large monitor has distorted display


try adjusting your system resolution to a largest one (as 1280 x 800), or using a DVI cable, if your monitor and video card supports it.

I am new to this fixya thing, but I have been working on televisions for over 20 years. So please let me know if you have any questions about the advice that I give.
If you can solder, solder the convergence IC's they are the big black IC's that are bolted to large heat sinks. I have found small ring cracks on the legs of the IC's. In some cases the legs of the IC's can separate from the IC's. But, overall I would say that this is an intermediate repair, and can be done by someone with a good soldering iron ~45 watts and some patience.

Blue streaks across picture


Can you describe in a little more detail what the symptoms are? Are the streaks thin lines or are they large thick swashes of Blue? Is yur video still visible? Sounds like it may be the blue convergence amps or the resistor tied into the amps. is there anyway you can post a picture of your screen distortion?

Dvd playback


Maybe it's something with picture settings, i.e. NTSC/PAL or INTERLACE/PROGRESSIVE SCAN.
