Strange convergence problem on my Philips projection TV


The only real test is to try to adjust the convergence for each color...Red and Blue...If you cant move both colors in all directions - up - down - left - right...then your Tv has a convergence problem. Try in both 480 and 1080...if it can't be adjusted - replace the parts. I just did mine the other day

You need to take the Toshiba remote that came with the machine and go into a menu area that deals with convergence. Here's what the manual says:

This TV used 3 separate TV tubes, red, green, and blue. The R, G, and B images are pojected onto the screen wheree they converge to form a full-color picture. You can see a clear picture only when the three images converge correctly. Corvergence my drift over time, or if yo move the TV. I you can see clear images on your TV screen skip this procedure.

Make this adjustment only after the TV as been on for at least 30 minutes.

Press the TOUCH FOCUS (auto convergence) button on the front of the TV at the bottom.
The TV will enter into the convergence mode and adjust the converge automatically (that's what it says.)

TO ADJUST IT MANUALLY:

Press MENU, and the press < or > until the PICTURE menu appears.
Then press UP or DOWN to highlight CONVERGENCE.
Press < or > to display the Center Convergence menu

There's a lot more the book says, but, I can say from experience that you just go through the different sub areas of this menu and converge each color separately, and bingo, it's fixed.

Good luck.

Hi,

Hitachi Convergence

Check out the Convergence Gallery. If you see the colored outlines or color shading as in the Gallery, you have a convergence problem.

The repair for a Hitachi requires the replacement of the defective IC or ICs and any damaged or smoked resistors. Some models don't have a separate convergence board and the board is not usually available for the ones that do have a separate convergence board. Usually there is little alignment required after the repair. If you play with all the adjustments before the fix, hours may be spent re-aligning.

If you change the original ICs with substitute "new and improved" parts that are talked about in the blogs, you will probably create problems. Use the original ICs and resistors.

Don't monkey with it.

This is a delicate and difficult repair. If not done by someone with some electronic repair experience, the TV will likely end up as junk or cost considerably more for a tech to fix the damage done.

If you live in Calgary, call me. If elsewhere, find a competent tech.

ronniezay,
Don't replace the convergence board, but take it in and have the convergence amps replaced. That unit takes two stk392-110 IC's and are fairly inexpensive compared to replacing the entire module. In fact, ask to have them replaced with a more reliable stk392-150's...
