I have a Toshiba 48pj5ue rear projection TV with some small convergence issues that can't be adjusted out with the standard user controls.
I would like to know how to access the sevice menu to do finer adjustments.
I'm sure it's probably similar to most Toshiba rear projectors in it's menu structure so if someone has something similar and knows how to access the service menu, I'd appreciate some help.
I tell people all the time
if you get into the service menu and hit the wrong buttons
i wont know what you did to it
again if you post here to ask how to get into the service mode you dont have the desire to find the codes on the internet which are readily available as are service manuals
turn on the tv
push mute on the remote till mute goes out
hold down mute button and push menu on front of tv
hit menu again when the s comes up
hit 7 on remote and watch out
you just figured how to reconverge your tv

Thats the way it works. You have to adjust the other colors to the red. You adjust the red from the back of the set using the convergence magnets on the tubes. Then you adjust the other colors to match the red. It's much easier if you have the plastic screen from Toshiba used to align this set.
This would be a convergence adjustment. Check your user menu on the tv. Look for an item under video settings for a something called "Converge" or "Convergence". See if you can adjust it enough to fix the problem. If not, you may need to access the service menu and adjust from there.
It sounds like a convergence problem---go into the customer menu and select convergence---set should offer center and multipoint adjustment--in the multipoint look to see if the outer crosses adjust--if red or blue will not adjust somewhere--bad convergence IC's.
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.
There is no code for sevice on this set when you pull up menu and to to setup do you see convergenge if not you have a blow fuse next to your flyback on power supply broad FL231 middle fuse they look like capacitors small brown square.

You probaly should be able to access the controls for that through the service menue. I dont have that info. However you can get a service manual for 10.99 at the following link, and if you purchase one they will mail it to you, unless you go back to the site and click on the contact them link and request that it be emailed to you. they also offer free support with the purchase of a manual so they can help you diagnose your set. I am one of their techs also. Heres the Link. http://servicemanuals.vstore.ca/
