IF model number is 51F500 and you go into the customer menu and convergence will not adjust or is skewed and 3d one or both of the two convergence IC chips this set uses is bad.

Usually in this set they are either STK-392-110 OR STK-392-150----both are essentially the same part but the 150 chip is a higher current and longer lasting part.

Both chips and any of the protect resistors around them that are bad need to be replaced and the set adjusted with the Hitachi remote.

Considering you can buy a pair of the chips on Ebay for about 12 dollars plus shipping, if you or someone you know can do the repair you can save the set and a lot of money.

Most shops are going to get 300 or MORE for this repair. The repair takes about a hour to do and should be able to be done right in your home---I know as I have done HUNDREDS of them here in people's homes.

There is a wave in the picture only in the upper left hand 1/4 or the screen. The rest of the screen is sharp. You get the colors separated and thus double image.

I have a HCN4727w samsung. Red/green shadowing. Bowed image


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 or bowed
*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

PHILIPS 60PW936317 - COLORS GOT DISTORTED AS I WAS WATCHING TV


Your convergence chips and convergence resistors are going bad. When they fail the screen colors will look distorted/3d looking.  Another symptom is one or more colors can't be converged using the convergence menu. You can purchase the parts over the internet. Just make sure you get Sanyo brand convergence chips and the correct flame proof resistors. You can also check the site www.TvRepairKits.com. They are working on a complete kit for this model.

Screen image display distortion


Hello.
What you are reporting is a problem in the pincushion circuit in the horizontal section of your CRT monitor. Usually this is from an electrolytic capacitor that is no longer willing to play nice with all the other components.
It is repairable, but get an estimate first. If the repair bill appears to be around $100, you would be better off to put a few more dollars with that and buy an LCD TFT monitor.
If you are quoted $25 or $30, it is probably worth having repaired. Just keep in mind that these older CRT monitors have age on their components, and once repaired, it will still be an old monitor.
Only you can decide which choice is right for you. At least now you have a few facts to help make the decision.
I hope this helps.

Sony DSC-W70 LCD Problem


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. David Millier Advance Camera Repair
