This is a convergence problem that you can fix if you can solder. Let me know if you wish to attempt the repair and I'll post additional details and instructions.

PICTURE ON TV LOOKS BENT. ALL STRAIGHT LINE ARE CURVED


In order to provide a correct dianosis and cure, I will need to know the model number and in which direction the bow occurs. Does the curve occur from the top and bottom toward the center or from the sides toward the center? There are different circuits involved in these case.

Please update this and I'll provide a solution.

Thanks,
Dan

Picture is blurry picture is curved


Need a better description. Sounds like either lack of B+ supply giving lack of width, low EHT, or you have East West transductor circuit being faulty. Is there lack of width and is it bowed in? Might be a dry joint around this area as the transductor resonates at line frequency making this dry jointed. Need a manual meter to diagnose correctly I am afraid.

Screen is bowed on top and bottom.


Projection sets have two very common problems outlined below.

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. The TV can also shut down when the convergence starts to fail.

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, RCA and others.


You can more info and a DIY convergenece repair kit with instructions from TV Repair Kits using the link at the end of this article.

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

PICTURE CURVED


I have the same problem, it is called the "bow tie" effect, I read in a forum a couple of years back it is because they started computer sodering instead via humans and it was not successful during that time. I bought mine in 02. I was hoping to find a picture of the the board and the specific soder joint on this forum. I hate to pay alot for a tech, (specially since it was mitsibitsi's poor craftmanship) and a 65" is not something you throw in the truck and take to them. Good Luck.

Sony FD Trinitron WEGA KV-36HS500 36" TV - Bowed Picture


it sounds like a convergence adjustment problem. If you hava book on the tv still read it, and it will tell you what to do, other wise, look for a convergence button on the front of your tv, and take the remote and push menu to bring up setup, and go convergence adjustment click it and hit the conv. button on the front of the screen. there should be to lines going vertical and horizontal, these are the limes you adjust with your remote, you have to adjust the red and blue, the tv should blink to let you know which color you are on. when you have them lined up right the line will be perfectly white. hope this helps

Edges of Picture & Text Sloping


This mis probably a cold solder connection in the horizontal circuitry called the pincussion. Theres a couple of coils and resistors that overheat from time to time and the solder connections get loose. Not really for a handiman has this tv has hi vboltage inside even when turned off. Shouldnt cost an arm ans a leg to fix if the repair shop knows what they Are doing. Good Luck
