Question about Akai PT4298HD Rear Projection Television

1 Answer

Akai Convergence I have been using 2 and 8 or the channel up/down but it does not move. 4 and 6 and Vol Up/down let me move right and left. I checked all the resistors they seem to be fine, but there is one large fuse on the Right side of the board that does not give any reading on the multimeter. the two smaller ones underneath the stk's do.

Where is the auto convergence button


Hello
From it menu option, suf through and come to automatic convergence display option and press Ok button on the remote control.

The List & Labels part of the setup lets you edit your channel list and choose or create a

personal six-character label for each channel.

Note: Changing List and Labels can be time consuming. You can change these at a later time by accessing the

Setup menu.

1. Press the left or right arrow to scroll through the available channels and choose the

channel you want to edit.

2. Press the down arrow to highlight the In channel list option. Press the left or right arrow

button to add (the box is checked) or remove (the box is unchecked) the channel from the

list.

3. Press the down arrow to highlight the Channel label option. Press the left or right arrow

button to scroll through the available list of 25 most common labels. The last option in

the list allows you to create your own six-character label for the channel (the first letter of

the label is highlighted).

4. Press the 1 or 2 number button to change the first letter of the label.

5. Press the right arrow to highlight the second letter, then press the 1 or 2 number button

to change the second letter, etc...

6. When you are finished creating your label, press OK. For model D34W20, your TV tunes to

Auto Convergence (for models D40W20 and D52W20 only)

Your TV's picture tubes might have been disturbed during delivery or after you moved the TV,

causing the color in your TV to be out of alignment. The colors adjust by starting auto

convergence.

1. Press OK to begin auto convergence.

2. When the auto convergence is complete, the Red center convergence menu appears. The

cross in the middle of the screen should be yellow. If it is not, use the arrow buttons to

move the red cross to overlap the green cross. Press OK when adjustments are complete.

3. The Blue center convergence menu appears with a cyan cross in the middle of the screen. If

it is not, use the arrow buttons to move the blue cross to overlap the green cross. Press OK

I replaced the converegence chips on my Akai PT4298HD I can move the grid up and down but not left and right because not sure which buttons on my remote move it that way. The picture supplied of the one...


Hi,

You should be able to use the number buttons on the remote to move the cursor to the correct crosshair:

2 = UP
4 = LEFT
6 = RIGHT.
8 = DOWN

After moving the cursor you can adjust the convergence as follows:

CHANNEL (CH) UP = UP
CHANNEL (CH) DOWN = DOWN
VOL+ = LEFT (?)
VOL- = RIGHT (?)

Not sure which way round it is for left and right but you'll find out as soon as you press one of the buttons.

Hope this helps. Please post back if you need further assistance.

Regards,
BElectric

Do not open anything until you. Go to menu on your remote find convergence and press the volume button to the right go to manual and press right again. you should see a bunch of rectangles, now you should also see a set of red cross heirs press the #2 to move cross heirs up and eight to move down numbers 4 and 6 will move left and right and 5 will place the cross heirs back to the center once you have chosen the selected section to adjust line up the magenta with the other colors using the channel and volume buttons these move the lines up down left to right adjust all lines until they are white. i do not know how to switch from magenta to green or blue but this should get you started on the right track with out having to replace anything. good luck! if you figure out how to switch from maqgent to green or blue please post it so that I may adjust mine as well tahnks

Your convergence has failed and needs to be repaired. Once quick test is to goto your convergence menu and see if you can adjust red and blue. If not its has failed and needs to be fixed. You can call in a repair shop or you can get the parts and instructions from www.TvRepairKits.com and do the repair yourself. Its a fairly easy DIY fix.

Good luck.  I let a sub-standard service joint work on mine - they replaced the OEM chips with a higher wattage equivalent, and I've had nothing but problems ever since.
