Question about Toshiba 55H70 55" Rear Projection Television

1 Answer

The link to the service manual was great.

With your help in getting the service manual I was able to get in the service mode on the tv and correct the green alignment in more detail then the remote allows you. The money spent for the manual was nothing. I will definitely recommend you to other FixYa Friends. Can't thank you enough.

How do i set convergence of red,green ,blue through service mode


Most common cause for this on the Sony KDL 40EX520 is that the connections to the screen across the top edge of the panel become loose causing blurred picture, mis-aligned colors etc. The Fix requires dis-assembly (Removal of the entire case) and re-seating/resecuring the connection across the top of the LCD Panel.
There is a pretty detailed video of the process (less the disassembly) here: https://www.youtube.com/watch?v=80PfZXFGDvQ

Toshiba 57H82 convergence problems. TouchFocus


See my solution <http://www.fixya.com/support/t2795690-convergence_off_blue_line_only_vertical>.
You need to get to the service menu--it's been 4 years so go to AVSforum.com to turn off the different guns and get the better pattern.
At your risk: To get into Service mode:
1. Turn your TV on. 2. For X81 or earlier series: Press MUTE on your remote and release. 2. For H80/H81/HX81 series: Press MUTE on your remote and release two times ("Mute" on-screen) 3. Press down MUTE on your remote again and hold. While holding, press the MENU button on your TV set's front panel. 4. Release both buttons. 5. An "S" should appear on your screen. Press MENU again on your TV. 6. Now you're in service mode. Channel Up/Dn - Scrolls through Parameters and Volume Up/Dn - Changes Parameter Value
To get into convergence mode:
Get into Service mode, then Hit '7' to bring up the convergence grid. Buttons 100, 0, and ENT control which gun you want to turn off (if you want to align the red to the green without seeing the blue gun and other variations). 2=up, 8=down, 4=left, 6=right, 3=change gun to converge, 5=converge that point. To exit convergence mode you press 7 once and your screen should look like it's imploding then return to normal and then you press 7 to get back into regular service mode.
I have more info found on the board. -Ken

Adjusting the convergence after replace convergence chips


Hello fmnii,

Believe it or not the easy part was the replacing of the convergence amplifiers. Now for the hard part, static and dynamic convergence of the TV. To do this, what I usually do is not trust the onboard cross-hatch and alignment patterns, for this I use a signal/pattern generator to create the cross-hatch and alignment patterns. I follow the static convergence instructions first, and then the dynamic convergence instructions. This process taks about 6 - 12 hours (Yes 6 - 12 hours) if done correctly. I say use the instructions because each TV set is different. It sounds like you have your static convergence well in hand and you just need to do the dynamic.

If you can, try to get a signal/pattern generator (I use the VA62A).

I wish you well,

Thank you,

Philips 23PF9966/37 color problem!


Try to adjust it in the Service Alignment Mode (SAM).

Press 062596 followed by the STATUS button (upper left). Navigate to "White Tone", press the right key to enter and select "Normal" mode. Set the colors:

Red = 135, Green = 128, Blue = 133.

The "Cool" and "Warm" menus are deltas from the "Normal" settings:

COOL: R -3, G -1, B 5
WARM: R 2, G -3, B -13

Press the "MENU" button to return to the main menu, then the "Power" button to turn the TV off.
