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.

I need the service mode sequence for my philips 51pp9100d/37 so I can manually change the resolution on my tv. The resolution somehow was changed and when I HDMI my laptop to the tv it wont display t

I suspect that you may be using a cable or sat box rather than that set's internal atsc tuner.
Sometimes these boxes are not set up properly or reset themselves to a lower resolution.
Go into your box's settings menu nd look for the resolution settings. Verify that all of the modes or at least the maximum resolution for your set is enabled.

Here is a link where you should be able to obtain a service manual for your set.

To answer your second question. You have to be careful. Make sure you write down all current settings so you dont mess the Television set up worse. The code is the following.
Accessing the Service Menu w/ Remote:
  • in the setup icon, set anntenna to cable
  • in timer icon, set sleep to 30
  • exit menus & tune to ch. 124
  • adjust volume to -0-
  • press volume down on the set panel & red "CHK" appears onscreen
  • use tv/video button to change video inputs
  • use POWER button on remote to toggle menus
  • navigate service menu with up & down, L&R and action button
  • images are tall & skinny. you must adjust the vertical size & position in the NTSC mode, as these are global.
  • Then set the horizontal size & position for each mode(NTSC, 525p & HDTV).

    TIP: Use a dvd that has an aspect ratio of 1.85:1 (I used Starship Troopers) and make it just fit. Don't squeeze too much vertical as the AA9a60 may have some tearing on the top of the picture....this means you will have to cheat and increase horizontal size, cropping some info off the sides.
  • Try using ch.199 & the HBO logo to adjust...the "O" in HBO should be perfectly round (HTPC owners can use VE DVD and the ANAMORPHIC test pattern: title 20 chapter 5 I think). Now you will find your geometry is bowed & convergence is out of whack.
  • First do a STatic adjustment, then do a DYNamic adjustment.
Navigating the Dynamic Convergence Menu
  • cursor buttons- moves cursor postion up& down, L&R
  • #1 button-cycles thru each color gun & combos
  • #2 button-cycles test patterns (normal & dense)
  • #5 button-shows program material in background
  • #7 button-save this often as the set sometimes shuts down in the middle of your work!
  • mute button: cursor data..push to adjust current position.
  • swap button- confirm
  • power-exit
For your final question You should have( 2) STK392-110 convergence ICs in that model. Thats probaly your problem. I would recomend changing them out before adjusting any setting via the service mode. Thes ICs are available from for 5.99 each. Hope this helps let me know if I can be of any further help.

Help please stuck in service menu

You should have purchaced the service manual before you went into the sevice mode, as the service mode is a dangerous place to be if you do not know anything about it. You can get the service manual from for about 20 bucks or so. A lot less expensive then a serviuce call I would think.
