The problem was with my cable providers (Knology) cable box settings. Somehow they had changed to zoom 1. I think this happened when I played a VHS tape. If this keeps happening everytime I play a tape or DVD I'll have to remember to reset the vidio on the cable box after each tape or dvd.

I tried looking up the image of your recorder online to help you out but I cannot find a clear image. If you can get me clear pictures of the unit I will help you out.

Overhead Projector Tip- best results!!


For best results, slant the screen forward slightly so it meets at a 90 degree angle with the projected image light beam. In not, then a keystone effect results where the projected image is taller on top or on the sides; in other words, the projected image is a parallelogram, not a square.

Image distorted on panasonic nv-fj620


I can't say for certain but it sounds like the video head might have gone. The good news is that you can get the parts from Curry's Partmaster website. Perhaps cheaper elsewhere? The bad news is that video heads are not cheap!

I don't know how you cleaned the head. So I would advise trying again to make certain. I would recommend cleaning with Servisol Video 40 several times. If that still doesn't work I would assume the head to have gone.

My VHS tapes have great sound, but there are white flashes going from left to right. Have tried tape on other machines and work fine. What do I do next?


Take the top off and clean the video heads with Servisol Video 40 which you can get online, image below. You can use cotton buds for the hard to get to areas.

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.

The image projected is squished


It sounds like your input signal is in 4:3 and the projector is in 16:9.
You need to adjust the "Resize" mode.
On your remote, press the "Resize" button (bottom-right of the remote, looks like a screen with two arrows pointing left and right [< >]) until it is in "Normal" mode. If that does not work, try setting it to "Border".

When we turn the power on iit only stays on a few seconds then turns off with the cst.in light flashing.. what does this mean and what can we do to fix it?? tks


I had the same problem. We watched a DVD, and the unit worked fine. We went out for ice cream, came back, and decided to watch a VHS. Instead of taking the VHS, the CST.IN light flashed and the unit cut off after a few seconds. We didn't have a VHS in the unit at the time. After cutting the unit back on several times without success, I looked online for solutions. One person said to hit 'eject' 5 times in a row, but that didn't work for my unit. Someone else said there was a lever inside near the power button that ejected the VHS, so I checked that out next. I washed and dryed my hands well, and used my finger to jiggle the white lever. Then I saw that the tray that the VHS sits on wasn't all the way forward, so I gently pulled and pushed it. I'm not sure which of the two actions worked, but my light is now a steady green and my unit is working fine now. I am so glad because we've had this unit for almost 10 years now, and I really didn't want to have to buy a new one! Good luck!

Picture is stretched on wide screen a circle looks egg shape


Hello
This is an issue because most television programming is produced in a 4:3 aspect ratio. The minority of programming is high definition, which is produced in a 16:9 aspect ratio. Because televisions are made in either a standard (4:3) or widescreen (16:9) format, there is always a conflict with an image being stretched vertically or horizontally. In the case of widescreen televisions, the stretching is horizontal.
Picture Modes
Luckily, most if not all widescreen televisions have a picture mode that allows the user to toggle between a wide (16:9) and standard (4:3) mode. This means that a person can watch non-HD programming in the 4:3 picture mode, and then go to widescreen when watching HD programming. Some TVs have a picture mode that will automatically adjust to the correct aspect ratio. Other people will watch all programming in the wide picture mode, and learn to adjust to watching a stretched picture.
A stretched picture is when a 4:3 image is pulled on the sides to fill the entire screen. People and images end up looking fatter/wider and shorter.
So, what's the big deal?
Some people don't like a 4:3 picture stretched or distorted because it does reduce the overall visual and picture quality. Some people don't like the bars on the side of the screen when a widescreen is in a standard (4:3) picture mode because it looks different.
Solution
There is no fix-all solution for this issue, unless you own a TV that will automatically adjust to the intended aspect ratio. The stretching of the picture is a side-effect, the price we are paying for the better resolution that is digital and high definition. This is definitely something to consider when buying a television, but keep in mind that there is no right or wrong within this issue. It is just the way it is, and there is no way around it unless you buy a 4:3 aspect ratio television.
Hope these lines will clear the issue, if so do rate the solution

If you are using the composite cables (RWY) make sure the red and white are plugged into the audio jacks and NOT the component cable plugs (RGB.) If you have the red audio cable plugged into the red component plug this will cause issues, especially with the sound.
