Lines and distortion across screen when on. If picture is taken it shows those lines and distortion

Check and replace the smoothing capacitor used at it video output voltage This capacitor can be located at the neck board of picture tube.To get more details, http://electronicshelponline.blogspot.com/ Pull up older posts.

At first the picture is ok, and then distorted with horizontal lines i thinks. If the horzontal lines are parellel acros the screen, with an inch apart across the whole screen, your tv needs screen adjustments. Screen voltage may be high. look into the crt base also. Change it first. These also not resolve the problem, LOT may be faulty, with respect to screen focus pack. May need replacement. Try first setting screen voltage to a lower settings and observe.

Projection sets have two very common problems.

The first common problem is convergence


These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. This is called convergence.

When its out of alignment the video will look 3-D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired. Convergence problems are very common on all Projection TV sets including Sony, Samsung,JVC,Philip Magnavox,Panasonic,Akai,Pioneer, Hitachi,Mitsubishi,Zenith and others.
You can get more information and a DIY convergenece repair kit with instructions from the link below.

Here are some of the most common problems with these sets...

*Screen Looks 3-D
*Colors wont align
*Screen may look distorted or warped
*No Audio/Video - TV Shuts down - May also make a constant chirping sound

Problem #2 - Another common problem is dull or washed out video.

Your set may have one or more of the following symptoms....

*Dull looking picture
*White looking picture
*Halos around objects
*Red/Orange looking picture

you need to test all cables then make shure it is not your tv.

Dear dkserv:

This is almost certainly a CCD image sensor problem. The PowerShot A70 has a Product Advisory on this very issue and if you are indeed experiencing it, Canon will repair the camera at no charge regardless of how long you've owned the camera.

If the LCD screen shows this distortion in all shooting modes, yet you can see the menu (press the MENU button) just fine and/or any images taken previous to the malfunction without distortion then you've got it!

Call Canon Tech Support at 1-800-828-4040 (M-F; 8 am - midnight EST) and tell them you think you might have the CCD Image Sensor issue and they will take care of it.

Hope this helps.

Sincerely,
HeavyDLB

Sony is fixing this through Sept. 2008!

Gimbo again. Think LCD damaged will need to repair. Pics. as normal when viewed or printed.
Why has nobody commented?
How much to replace screen? Any ideas?

Can you describe in a little more detail what the symptoms are? Are the streaks thin lines or are they large thick swashes of Blue? Is yur video still visible? Sounds like it may be the blue convergence amps or the resistor tied into the amps. is there anyway you can post a picture of your screen distortion?

Your camera likely needs a new CCD imaging sensor. It is a cute little thing and is very expensive to replace. I've seen deals to repair any digital camera on eBay and I would check for a local repair person in your area. You can use the search on this site to see who might be close by. I have an A310 doing the same thing.

This is due to vertical section failure. Change the vertical supply rectifier diode and supply filters. Then check zener diode leakage in pumpup circuit section. Also check any electrolytic capacitors leakage in vertical section. If it is old model tv change vertical height, vertical lenearity presets also. I hope given details useful to you.
