If the picture looks kinda 3-D
Normal 0 MicrosoftInternetExplorer4 /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin:0in; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:10.0pt; font-family:"Times New Roman";} The best advice I can tell you at this point is to go to tvrepairkits.com and order the complete convergence kit for your model of TV set, no need to search and order multiple parts from different sources and pay multiple shipping fees! The kit comes with original Sanyo STK IC’S , not those cheap aftermarket or china made IC’S full pictorial directions, the thermal paste, resistors, the correct Pico fuses, AND free live on-Line tech assistance in case you run into a problem with the repair. They ship out 2 to 3 day Priority mail, the next day in most cases you may need to open the set and tell them what the STK numbers are on the chipsGOOD LUCK!!!

Convergence panasonic HDTV 1080i bbe hi definition


The most likely cause is shorted convergence chips and possibly a few pico fuses.

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 a convergenece repair kit with instructions from the links below.

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

Problem #1) Convergence

Yours may have one or more of the following symptoms...

*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 can see some more examples and find a fix herebb0cf99.pnghttp://www.fixya.com/support/r2861467-solution_video_looking_whiteish_dull

You probably have a convergence issue. Since you did not include your make/model there's not a lot that we can do to help you. Try searching your model number with the word convergence in the search criteria.

Problem with HD feed from satellite receiver


I just had my HD DTV installed this weekend, you have to leave it on 480p. I too purchased my tv in 2002. Per DTV, its an older model and you have to stay with the 480p to get the best possible picture. I have to admit, don't know what the 1080i looks like, but 480p is showing me a very good picture. Best I have ever seen on my TV.

Picture is concave on top and bottom. With ed and green ghosts.Worked fine, turn set off and on about 15 minutes later and picture was as described. Help!


The convergence chips in your tv have gone out. They control the three picture tubes and align them so that they create one picture on your screen. I recomend having a qualified technican replace them and realign you convergence. Thanks.

Ghosts on my tv


if you can, try hooking up the tv to a different cable line in the house or bring a different tv into the room where the bad picture is [ you may have a bad connection or wire ] if this doesn't help, try rabbit ear antennas just to get a picture. if you still have ghosts on your tv, the problem is with your tv.if the picture is fine, there maybe a problem with your cable service.
hope this helps

50" rear projection sony HDtv and ghosting when using my ps3


To bring up the "service" menu, put the TV in standby mode, then press in sequence :

Onscreen Display ( the little screen with the i+ in it )
5 ( channel number 5 )
Volume Up ( upper end of volume button )
Analogue ( middle top button )

The TV should switch on and when it's warmed up, you should see a screen with lots of big green lettering on it.

Press the "menu" button ( middle bottom )

Use the direction dial to move down to "LCD Drivers" and press right on the dial to enter this menu.

Move down to "S H Pos Reg R". It should be "10", change it to "11". ( Left/Right to adjust )
Move down to "S H Pos Reg G". It should be "10", change it to "11".
Move down to "SHPos Reg B". It should be "10", change it to "11".

Press the menu bottom to drop out of the menus, and the standy button to drop to standby. Switch back on, and hopefully your ghosting will be gone.
