I have a toshiba tp50h50 rear projection tv and their is a blue shadow behind the words and makes the words a little blurry


Sounds like you need to do a color convergence. If you still have the owner's manual, it will give great detail on how to do this. The convergence menu is accessed from the video menu on the tv.
The tv has three color picture tubes, red, blue and green. The convergence alignment adjust each tube so that color from each tube overlaps each over to create a white image on the screen. Most tv's only allow you to adjust the blue and red colors.
Convergence should be performed each time the tv is moved and at least once annually.

There is a red shadow behind words and picture, is there an adjustment I can make?


you can try MENU... settings to alter the convergence red.. blue... green factors. But you could end up making it worse

I suspect the prblem is beyond the usual user adjustment and requires professional intervention inside the unit. It may even need the color engine replacing ( $300) It is not a DIY as many before you have experienced despite the warnings. DIY can end up costing 3 times the rate of a real tech.

Hitachi projection tv 53SDX01B is out of focus how do you reset.


if magic focus will not correct convergence problem look in the customer menu for the word CONVERGENCE---IF BLUE WILL NOT ADJUST IN some direction, one of the two Stk-392-110(or 392-150) convergence Ic chips are bad; you may also find some burnt or discolored resistors behind them----this kind of problem is usually fixable right in your home; if you need direct help;;;

Kp-46wt500 shadow and slanted images with rainbow colors


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 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 need to replace the convergence chips and convergence resistors. Check the site www.TvRepairKits.com. They have put together a kits for most models. If you don't see a kit for your set send them a quick note and they will put one together for you. Their kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, etc.

Not sure, but looks like blue and red shadows around words on the screen


Al, bring up your convergence grid (look in menu for it) and I think you`ll find that the set is out of convergence, if you can adjust the red up & down and the blue up & down your ok, if they won`t move in one or both directions the convergence IC`s will have to be changed out, hope this helps, BMW Rider
