Does the problem occur while watching dvds. it is possible that it is an issue with your tv but i would try switching off of cable to a game console or dvd before i said for sure it was the tv. you also might try using another port on your tv such as hdmi, s video, rca or componet ports . if any of those ports work i would replace my cable from the cable outlet.

How i adjust horizontal size and vertical size


To answer your concern, all you have to do is to change the setting of your aspect ratio on your TV.

Here is my suggested way to procede:


1. Apply 1080i signal, which should produce an oversized HD image on ColorStream1or 2.
2. Select an HD channel that is broadcasting standard 4:3 image, not wide screen.
3. Switch to the Service Mode ( Please refer to the above links). In the Service mode, press channel up/down to find the Adjustment parameters needed for the following steps.

4. Adjust HIT with volume up/down control for the image height to 22.5 inches.

6. Adjust WID for image width of 30 inches, (22.5*4/3)
7. Adjust HPOS to center the image.
8. Adjust PARA and TRAP to minimize geometric distortion.
9. Switch into Convergence mode and Adjust VLIN to get equally spaced horizontal grid lines.
10. Measure the length of the central grid lines and note the number of horizontal and vertical grid lines. This information is used to create an overlay grid.
11. Create the overlay grid on 40x25 x0.003 inch clear Acetate sheet, which you can get at the Art Supply store for under $2. Draw the grid with a fine line erasable pen. Draw vertical and horizontal lines through the center of the sheet so that the lengths are the same as the central grid lines. Now draw the grid so that it has the same number of lines as the convergence grid but are equally spaced, with the outer ones at the ends of the central lines.
12. Cut off about 1/4 inch from the right side of the sheet so that the sheet can lay flat against the screen, which is slightly less than 40 inches.
13. Put a reference mark on the TV frame 2.5 inches down from the upper left side of the screen.
14. Place the overlay on the screen so that the upper edge lines up with the reference mark. The overlay sticks by electrostatic attraction.
15. Use convergence controls to remove grid distortion and converge grid colors. Refer to the Anamorphic link for details.
16. Enjoy 1080i.

Other Comments:
I didn't realize I could create the overlay grid before placing the Acetate sheet on the TV screen, until I finished drawing the grid with the sheet placed on the screen. I added grid lines as called for in the procedure. I'm sure this method took much longer no only to draw the lines but some of them were difficult to see.

Part way through the convergence procedure, I became concerned that the image width was off since I did my screen adjustment with wide screen image. Thus, I decided to repeat that step with a 4:3 screen.

I confirmed the need to press 7 often to save results since after I adjusted one grid color without it, I accidentally hit a key that switched me out of convergence mode and when I switched back, all settings were gone.

Another mistake I made was not realizing that the cursor color determines which grid gets moved.

Pls. check your antenna line if it is still connected. Blue screen happens only if your
tv is not getting any signal from your indoor or
outdoor antenna.

I have a 1985 Zenith Space Command Color TV. It has developed thin white lines at the top of the viewing screen. The rest of the screen is clear. Is it something small or am I looking at a new picture...


The picture tube is fine.
Those whites lines at the top of the screen are caused by a dry or leaky capacitor(s) nearby the vertical amplifier IC.
Let me know if you require further assistance.

Convergence no good on lower corners and upper screen


I'm assuming you used STK392-110 for a replacement. You could use STK392-150 for greater reliability and don't forget a good heat sink compound. (VERY IMPORTANT). What it sounds like is something even the best of techs battle. You probably didn't buy original Sanyo STK's but instead got a couple of the JApan knock-offs. Might I suggest you carefully replace them again and this time order them from B&D Electronics, Bdent.com on the net. You are assured of getting quality OEM replacements that way... We've had a bad batch that purchasing ordered quite some time ago and 2 out of the 14 ordered worked.. The rest were DOA (dead on arrival). Good Luck Bill
