Lockup/crashes hi, my toshiba 43" tv keeps crashing/locking up - ie nothing works, vol, menu, power, channel change etc the only way to fix it is to turn it off for 1/2 an hour or so. ive been told it is probably the text board which i understand is a plugin module, so i can replace that ive also been told if i remove it , the problem should be solved(though ill have no text)....but how can i tell which is the text board / where is it located? thankyou for any help

see if anything here helps you out.... https://www.google.co.uk/webhp?sourceid=chrome-instant&rlz=1C1CHBD_en-GBGB719GB719&ion=1&espv=2&ie=UTF-8#q=Win7+keeps+crashing

I am unable to see at a glance how to correct this but it is between its menu, channel and volume buttons to alter the settings it may be worth to run through the re-tune sequence below?


To preset a channel or to change a preset channel, follow the procedure below.
1) Press the POWER button to turn on the TV.
2) Press the MENU button so that the menu display appears
on the TV screen.
3) Press the CH(annel) ? or ? button to point to "CHANNEL SET".
Then, press the VOL(ume) ? button.
4) Press the CH(annel) ? or ? button to point to "AUTO PRESET CH".
Then, press the VOL(ume) ? button.
The tuner scans and memorizes all active channels in your area.
? The TV distinguishes between standard TV channels and cable channels.
? When AUTO PRESET CH action is completed, the lowest memorized channel reappears on the
screen.
? When you press the CH(annel) ? or ? button after selecting "AUTO PRESET CH", the tuner
will stop at the memorized channels only.
? The TV may recognize TV channels to be CATV channels by the receiving conditions. In this
case, try AUTO PRESET CH action again in the fine receiving conditions.
? When AUTO PRESET CH is activated where there is no TV signal input,"NO TV SIGNALS"
will appear on the display after the completion of channel scanning.
[ADD/DELETE FUNCTION]
1) Press the MENU button so that the menu display appears on the TV screen.
2) Press the CH(annel) ? or ? button to point to "CHANNEL SET".
Then, press the VOL(ume) ? button.
3) Press the VOL(ume) ? button so that "ADD/DELETE" is selected.
4) Use the CH(annel) ? or ? button to select the
channel you wish to put into memory or to erase from memory.
Note: The menu will disappear in about 10 seconds.
Perform "ADD/DELETE" function while this display appears on the
screen.
? Press the VOL(ume) ? or ? button to light up the channel number
in LIGHT BLUE if you wish to add the channel into memory.
? Press the VOL(ume) ? or ? button to light up the channel number
in LIGHT RED if you wish to erase the channel from memory.
5) Press the MENU button to exit the menu.

Hope this helps.

You might try changing your browser (Firefox, IE etc) also see if you have the latest versions. It also could be stuff on your computer. You might want to also clear the cache and even do a complete virus scan if possible.

Some of these remotes are also made to run other components,so be sure to press the "tv" button and try the vol and channel again!

Can you turn it on with the remote? Do any of the other function swithes on the tv work vol,ch up,down,menu etc. If switches on set do not work check in menu for button lock feature. keeps kids from pushing buttons.

There is a button lock in the menu of the television. Using your remote access the menu screen and unlock the buttons.

1. Windows reinstall thru CD ( crashed graphic drivers )
2. screen itself faulty

this worked for our emerson....go to menu....go down to v-chip set up..chick on the volume button.....this should take you to something that will say tv ratings...again click on the vol. button. when I did this it showed that all channels were blocked.. again click the volume button and it should change it to view.. if it works this way for you then just click menu and you are done.

Have you tried replacing the EEPROM? It may have lost it's programming for that set. Stargazer

Please gives a description of how the tv locks up?...like... You can not change the channels you can not increase or decrease the volume with or without remote you can not bring up the menu or get rid of it You are correct if you remove this board you will loose the text and maybe more. You might get a different posibble reason. Please post it as a new question
