Should be 4 buttons, 2 on left and 2 on right. Press bottom left 3 times and hour offset digit will be displayed. Press and hold top left until hour offset digit starts to flash. Press either top or bottom right to adjust offset hour to correspond with your time zone. Eastern -5, central -6, mountain -7, pacific -8. These are negative numbers, not positive. Then press top left button once, then press bottom left button to return to time display.
What you most likely have is a convergence problem.The convergence circuitry is used to align your colors. What you describe sounds like that circuit has failed. Here’s a link to a decent video that will give you an idea of what is needed to fix it: http://www.youtube.com/watch?v=S6Wa8FvSz-s
Hi Sandy, the problem with your TV is called "convergence". It can be a problem with the convergence board or more likely in this model in the power supply or deflection circuits. Unfortunately, troubleshooting by a technician is required.
Replace 3 capacitors on Deflection board its the bottom left hand side cp150 200uf 16v use 25v capacitor and cp114 cp120 in same circuit 220uf 35v. You will see cap cp150 if it is puffed up on top they are Bad. Call Mats Electronis 1-800-628-1118 Radio shack might have capacitors.
do they look like these: ·http://home.earthlink.net/~oleg.filippov/ConvergenceFix.htm ·http://cmpalmer.blogspot.com/2006/11/fixing-my-own-tv-part-ii.html
You will need to describe what you see on the LCD in more detail in order for me to tell you what the problem is. There are two different issues that can cause things like what you are seeing.
1: Cracked LCD. You will see lines which resemble cracked glass. You will see bright vivid colors with specks of black or stark white all over. The image problems may be only in one portion of the screen. The LCD is made of glass, so if you look closely and see patterns that look like broken glass - this is your issue. Replace the LCD.
2: Bad LCD connection. You will see distorted colors, the screen may blank out and flicker when you shake the camera or press on the housing near the screen.
If neither of these describe what you are seeing, post back and give more details and I will respond further.
