Question about Toshiba TN50X81 50" Rear Projection Television

2 Answers

Toshiba TN50x81 50 Inch TV most of the images seem to have a ghost image behind them

Any one know how to correct this? I went into the menu of the TV and tried the Convergence option to try to correct the problem but then you have to choose between some numbers and I'm not sure what these do? I don't have the manual for the TV or I would have checked that first. Thanks for any help.

    ghost images, went to convergence menu and get no responce when trying to align the images, mostly blue color out of wack

  • indyjonez Jan 23, 2008

    I'm replying to my own post. I finally figured out the numbers and how to move the blue and red targets to match up with the white center target. What will happen is it will be fine (all colors lined up) for 30 minutes maybe an hour and then it will flick back to having the blue out of sync with the rest of the colors. I wanted to respond to Solution #1, how do I go about replacing the convergence ICs on this TV and if it is not something you recommend I do myself how much (rough estimate) would it cost to have these replaced by a technician? Thanks for responding Solution #1.

The convergence ICs are bad and need to be replaced. This is a common problem with projection TVs. These are large black ICs connected to a heatsink. Replace them and all should be well.

NO PICTURE!!!! Please HELP! I am going to kill my husband for bringing this TV home!

If the model number is correct and all you can get is the menu or on screen displays to work the set may need to be reset--not on the front or in the menu.

The set has 3 hidden menus: adjustment (keep out), tech convergence, and the OPTION menu.

Option menu enables a hard reset to factory of all settings except convergence and is designed to fix odd issues.

You need the Mitsubishi remote and a 4 digit code (model specific).

If you have the remote and want to try it let me know what the actual model number is and I will give you a link to the service manual which tells how to do it correctly.

How do you fix convergence on a sony tv?

If convergence in your TV went out suddenly and severely, there is nothing you can "adjust". That's a parts failure, convergence amplifiers I.C. chip(s) went south. Needs repair! Period! Minor alignments could be done by applying "flash focus" or "manual convergence" off "menu", if available.Some models have "flash" only option. Anyway, make sure there is no large metal structures near the front of TV or large speakers nearby. that could convergence to go out. Try not to play with any adjustments, if severe convergence problem. you won't be able to fix it right and will corrupt memory settings for "flash" option.

Need to know to set the convergence

Have you tried going to the service menu?
Do this by holding "MENU" on the TV set while it is on, then pressing "Menu" on the remote. You may have to do this a couple times for the menu to appear.

There should be a option on the appearing screen for Convergence, which has more options the the standard menu. To work this under the "9" setting for convergence, each of the + on the screen is the corresponding button the the TV remote (3 if top right, 5 is center). Use your volume or arrow keys then to move the selected + in the desired direction.

Good luck!

RCA 52 INCH CONVERGENCE PROBLEM HELP/already replaced the fl231 fuse

These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. When its out of alignment the video will look 3-D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired.

THis is very common on these sets. there is a special fuse thats cause this.. kinda hard to get rca part number 259213.. .4 amp. the reason this blows is there is bad solder connections on the flyback. so when you replace this fuse you have to resolder these connections. so if you know how to solder and can find this special fuse. it is a fast and easy repair

Convergence problem w/ red horizontal only-WS-65807

Do not try to adjust anything yet!! Adjustments do not get out of alighnment all of a suddenly. The convergence adjustments are there to do minor aging alighnments. I would first check for bad solder connections on the convergence IC's first.
