Check all the voltages at the other pins to its crt base socket. Check the video output transistor's solder terminal. Check the voltage that comes to green drive transistors' base. Refer its circuit diagram for more details. If you wish to get some details; check the site linked here. Viewing it in "Mosaic" or "Magazine" will make surf easy Pull up older posts.

Check the CRT base card to green CRT for any loose solder terminals. Re-solder all the suspected solder terminals by applying a little more solder to each terminals. Check the solder terminals of the CRT base connection socket too. The fault is with some loose solder terminal itself at the green video output stage circuit. Gopakumar Gopalan Google

Picture stays on for a few minutes then turns off.. what could be the problem? light bulb? can i do it myself?

This model TV is a CRT projection and does not have a lamp. It has 3 CRT tubes (Red, Green and Blue). Unfortunately, you may need to have a trained TV technician diagnose this further.

Green horizontal lines on screen no picture

The green CRT's (color picutre tube or color wheel, or ballast) will need to be tested for replacement.
It is quite common with these tv's

You will need an ohmmeter and or voltmeter and test each component for currency and accuracy

Problem with color

Yes you have a problem in the red crt driver board. Most likely the driver transistor is failing. This is a component level repair, so if you have no experience with TV repair, play it safe and call in a trained tech to assist you in this matter. Good Luck
