Poor Picture


Hello,

It's a convergence issue. Go into the main TV menu under video settings and look for convergence. If it has an auto convergence select that and wait a minute the TV will adjust itself and give you a clear picture.
If the TV does not have an auto convergence and just regular convergence than select this. It will give you a grid pattern on your TV and you have to move the curser (using TV remote) and adjust each "point" so that each line is perfectly white. If you notice red or blue anywhere on that "line" then you have to adjust using the up, down, left and right arrow keys to "line up the red and blue lines with the nearest white line. It taked time and patience to do, but when completed, all lines on the grid pattern should be pure white and you will have a great looking picture.
You have to do this will all TV inputs (Video1, Video2 and so on) the reason Zoom looks good, is because you never used that screen as much and so the lenses didn't have a chance to get out of synch.
RPTV's are made of the three lenses (red, Blue and Green) and as you watch TV, these lenses slowly get out of alignment. So you should do a convergence about twice a year to make sure nothing is out of whack.
Hope this help....

Panasonic pt-47wx53g red is out of convergence range


Have you moved the TV recently?, if so the red can(Red source) in the back bottom of the TV may have physically shifted in its holder, this is common when a rear projection tv is moved, jostled. Take the back off, look at the three cans,Red, Blue, Green, see if they all look like they are nested the same, bet the red is shifted a little.Good Luck with it!

Convergence lines are SLANTED. Red line is above


Your TV most likely a convergence failure. ( common problem )

Here are some of the most common symptoms and example photos of a convergence problem


  • Screen looks 3D
  • Colors don't line up
  • One or more colors can't be adjusted when using the convergence menu.
  • Screen is bowed or warped.
Here are some photos of convergence problems.

Here is a quick test....

Using your original remote go-to the tv settings then goto the convergence section.

Try to adjust the red and then the blue convergence.

You should be able to move them up, down, left, and right.

If you can't move them in all directions your convergence chips are bad and should be replaced. This is a common problem.

You will need to replace the convergence chips and possibly some convergence resistors and pico fuses. Its a fairly easy DIY job or you can call in a pro. If you want to do the repair yourself check the site www.TvRepairKits.com. Their kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, thermal paste, email/phone support, etc.

Can't turn TV on because buttons on TV locked accidentally trying to fix convergence


Hello Regina50,

I would suggest that you have a TV technician come out and check your TV. This may cost you a little bit of money, however it will be worth it.
Thank you,

43H70 Blue Convergence out of line and will not line back up


If the blue colors will not line up, and the blue appears to sag inward from one or more sides, then you can bet that one of your convergence IC's has either cracked loose or burned out. The IC should be resoldered or replaced and the convergence realigned by someone experienced with projection TV convergence circuits.
