How to fix the convergence on a toshiba TP55D81 tv using the remote control


The convergence is adjusted with the remote by entering a tech menu and adjusting there====if convergence is really bad adjustments are not going to fix it.

The set should have in customer menu a limited convergence adjustment with up to nine points where you can adjust---if it will not adjust there in some way----convergence circuit needs repair.

How do you access the convergence calibration menu on a RCA P52926 Rear Projection TV


Hello
To access the convergence calibration:

Press the MENU button on the remote.

2. Press 3 to select the Screen option.

3. Press 4 to select the Adjust Projection TV option.

4. Press 4 to select the Advanced Convergence option (the
Advanced Convergence screen appears).

The green pattern is fixed. The red and blue patterns are adjusted to

the green pattern. The Red Convergence appears first by default.

5. Colored cross-hairs show the current adjustment position on the

grid. To move the cross-hairs to a different position, use the

CH+/- buttons on the remote to move the cross-hair highlight up

and down, and the VOL+/- buttons to move it right and left.

6. Use the arrow buttons to adjust the red pattern. Each press of

the arrow button makes a slight adjustment from the center of

the cross-hairs - you can press and hold the desired arrow

button to make a faster adjustment, and then make fine

adjustments with single presses of the arrow button.

7. Press the INFO button to switch to Blue convergence and follow

the steps above to adjust the blue pattern.

8. Press OK to exit. You will be asked if you want to save the
adjustments

Yes Saves adjustments.

No Returns to the Advanced Convergence screen allowing

further adjustments.
Clear Exits screen without making any changes

Note: Before you use the advanced convergence feature, you must
complete the previous steps to align the tubes

Top of screen disappeared...cant see score of game


The Height adjustment is off... look in the back of the TV set, it has some knobs in the back, one should be vert.lin for Vertical Linearity adjustment, and there is another call Vert.Hgt. for Vertical Height adjustment. try adjusting the Vertical Height first with someone watching in the front of the big TV to see if the top comes back into view, you might have to adjust the knob very slowly one way then the other way, to make this adjustment. If it doesnot adjust take it to a TV shop to get it repaired.
Good Luck.

Convergence Problem and Contrast Adjustment


Have you checked all of the resistors inthe convergence circuit as well? If not, check them for the correct impedance.. Remember, you have to pull one side of the resistor out of circuit to measure it correctly. 
If all of the resistors are good, then you have to do a coarse convergence adjustment on the set through the service menu.. if you need the service manual for the convergence directions, I have one uploaded in the technicians corner of techlore.com
