    this does not work............i have tried it before

    the provlem possibly is the original remote control for this tv the mute button when pressed says 1/2 mute then u press again and it says mute.........not sure if that makes a difference but the procedure you just showed me does not work using the original remote

    are their alternative methods? is the procedure you jsut showed specific to this tv?? or just general


  • dcxguy48080 Oct 21, 2008

    and by the way the tv needs to be on correct?

    with tv on

    i have tried pressing mute 2 times on remote

    press mute 1 more time and hold

    then press menu on tv while still pressing mute on remote

    correct?

    this does not work


  • dcxguy48080 Oct 21, 2008

    thank you yes it does not work with my tv for some reason


    what us a eprom and is it repalceable and if so how would i do it




  • dcxguy48080 Oct 21, 2008

    thank you..........my tv is fine but it just needs a little fine tuning.........the auto converge doesnt work well........i have to manually converge which this model has in menu thank god lol to get the pic pretty good but there is just a small distortion in the bottom left part of screen maybe only 2 inches in that needs to be adjusted in service menu....from my expericen auto converge on most tvs does not work well at all........

    oh well i can live with it i got the tv for free..........

    thanks


  • dcxguy48080 Oct 21, 2008

    i want to make sure i was doing it right

    with tv on

    hit mute button 3 times on remote and hold on 3rd time

    then hit menu button on tv while still holding mute on remote correct?




  • dcxguy48080 Oct 21, 2008

    hey it does work...........you have to hit all bottons with no time in between..........

    i was doing it slow before.............thank you so much


  • dcxguy48080 Oct 21, 2008

    ok i got into service mode and hit 7 to get to convergence grid.........now what i have is a large grid with a blue small box and i can change the box to green and red and can move the box around but do you know how to actually adjust....what keys to hit to move the RGB up down left right converge....the directional arrows on my remote dont do anything




  • dcxguy48080 Oct 21, 2008

    thanks i got it to adjust i was trying to use the arrow keys........

    now how do i save what i did??

    i havent turned the tv off yet........and dont want to lose the adjustments i made


  • dcxguy48080 Oct 21, 2008

    thank you.........can you now please tell me how to save the data i changed

    i havent turned the tv off yet


  • dcxguy48080 Oct 21, 2008

    i found out how to save it.........thank you so much the picture is perfect now..........

  • dcxguy48080 Oct 21, 2008

    i did something different i hit the 1 key and then it says hit enter to load backup data

    i did that and it worked..........

    is that correct also?

    im afraid to hit touch focus at all since whenever i do touch focus it makes the alignment all out of whack



  • dcxguy48080 Oct 22, 2008

    one more question

    the tv pic is great now but the lower left corner is a little too low and the upper left corner is too low.......you can only really notice it when watchin ESPN with the scrolling scores on bottom of screen and sometimes top of screen.....seems like i need to move the left side of the screen up a little

    how can that be done in service mode??

    what adjustment is avail if any

    Thats the correct proceedure for the H82 series toshiba. Your eprom may be defective if you cant access the service menu

  • Sonny Berry
    Sonny Berry Oct 21, 2008

    The eprom is the main processor that has all the service menu parameters programed in. Its a large IC with numerous Pins which is very difficult to replace without the proper tools and it also needs to be reprogramed after installed . This may be better suited for a Toshiba authorized service center to repair.

Toshiba 42H82 Blue raster is bowed to the right in the middle to the rt. The auto convergence give an error.


You have convergence output failure. The output ICs will need to be replaced and possibly a small component like a resistor or two as well. Expect to pay a service company $350-$450 to resolve this.

Toshiba 42H82 RPTV: Sound but no picture


It sounds like the 200v supply to the crt's is missing. this is the source for driving the tubes, other than the high voltage generated by the flyback transformer. If the set got really bright gray with wome white lines that are kinda on a diagonal, this is generally the cause. the source for this voltage is a diode on the secondary of the flyback transformer.
