42wt29b toshiba tv

The problem is when it is switched on it takes ages to come om and then off, if i press volume this comes on as if the 3 guns are miss matched ie the colours, then it will come on properly then off again, removing the back i noticed that when the 3 tubes lit up it worked then went off again, could this be a faulty tray or power supply, also i cannot obtain a manual for this tv, can any one help thanks mike

Screen has been pushed in 42wt29b

If the protection screen is broken, Just take it out and replace it with a sheet of plexiglass. If the freznel lens is damaged I believe you will have a hard time finding a replacement. Good luck.

When i switch my tv on. I can hera the volume but no picture. Then the tv switches off and restarts until both the volume and picture is working. This could take up to an hour

yes. tv has a circuit which controls current to the red, green, and blue piture tubes. you wont get picture until they are balanced. adjust the screen controls until it comes on faster. it should only take maximum 20 seconds for a picture. gaurantee it will fix it. adjust the screen control

Toshiba 57H82 convergence problems. TouchFocus

See my solution <>.
You need to get to the service menu--it's been 4 years so go to to turn off the different guns and get the better pattern.
At your risk: To get into Service mode:
1. Turn your TV on. 2. For X81 or earlier series: Press MUTE on your remote and release. 2. For H80/H81/HX81 series: Press MUTE on your remote and release two times ("Mute" on-screen) 3. Press down MUTE on your remote again and hold. While holding, press the MENU button on your TV set's front panel. 4. Release both buttons. 5. An "S" should appear on your screen. Press MENU again on your TV. 6. Now you're in service mode. Channel Up/Dn - Scrolls through Parameters and Volume Up/Dn - Changes Parameter Value
To get into convergence mode:
Get into Service mode, then Hit '7' to bring up the convergence grid. Buttons 100, 0, and ENT control which gun you want to turn off (if you want to align the red to the green without seeing the blue gun and other variations). 2=up, 8=down, 4=left, 6=right, 3=change gun to converge, 5=converge that point. To exit convergence mode you press 7 once and your screen should look like it's imploding then return to normal and then you press 7 to get back into regular service mode.
I have more info found on the board. -Ken

Toshiba Regza 32C3000A tv sound keeps droping out, the mute button when pressed on and then off brings it back on. seems as if the tv is auto muting itself?

Could be a contact piece of the MUTE button from your remote that is causing it.
Go out and Big Lots or Radio Shack to get a cheap universal remote control(big lots would be between $5-$10) Pick up the code for it,and when the tv happens again,your the OLD remote MUTE button to turn it back on and then put away this remote control and use the new universal remote control.
However,if the problem is coming from the manual MUTE button on the TV,you need a repair tech, to fix it!

Toshiba 42wt29b. screen keeps turning blue

MMMM Hard call here. The fact that it does try to come on blue maybe an indication that the power supply regulator circuit is good. It could also be a shorted blue tube and when it comes on its overloading the screen drive and the set goes into overload protection shutdown. The real way to see Would be to pull off the blue crt socket as well as the Hi Voltage lead on the crt and see if the set comes on without blue. If it does Your gonna need a pict tube. If it dosent then troubleshooting along the switched power supplys would be neccassary.. BUT I advise you THAT IF YOU HAVE NO EXPERIENCE TROUBLESHOOTING TV SETS PLEASE SEEK A PRO TO ASSIST YOU AS THERES VERY HIGH VOLTAGE INSIDE THESE SETS EVEN IF THEY ARE UNPLUGGED. GOOD LUCK
