Question about Computers & Internet
Need more info. CRT I'm guessing. Either you have adjusted the vertical size control way out because the screen kept getting smaller. Adjust the vertical size to eleminate the retrace lines and the start checking the vertical out put circuit. Check your voltages. Most often the porblem is in the power supply or closely related. Screen voltage and contrast circuits may also be involved. You didn't give me much to go on. Good lluck.
