This could be a problem in the vertical sweep circuit, as when the vertical circuit fails, The video or screen will blank out so the picture tubes do not get damaged. In this chassis, I have seen the convergence IC's cause this, or the capacitor in the sweep power supply that feeds the voltage to the vertical IC has failed and blew out the vertical output IC. If you have no solid state repair experience, play it safe and call in a trained tech to assist you in this repair. Good Luck.

    You will need to get the service manual first. But if you do not understand how to read a schemaric, or a circuit diagram, it will be waiste of money

    Like I said before my friend, you will need to get a service manual and see where you are losing the video. It most likely will be in the protection circuit, so when the vertical sweep goes out or the vertical convergence goes out, it does not damage the picture tubes. Do you have a multimeter we can use and trace voltages with? If so and you can follow a schematic diagram, get the manual and maybe I can guide you through the circuit and see whats happening to the video.

    You need to buy a service manual first to trace out the circuit flow. We simply cannot tell you or guide you blindly without knowing what is in the circuit, and all sets are different. You will have to spend a little to fix this TV set I'm afraid. You will also need a multimeter, a soldering iron, and a knowledge of how the knowledge to use them. There is I'm afraid no magic fix to fix this TV set.

This is probably a cold solder joint on the bottom of the chassis. I would look at the Vertical IC first, then Convergence IC's. Then look over the entire board.

Toshiba 32a43 32' picture garbled mess


If you can get the tv to display the blue blackground(usually happens when there is no antenna or cable feed to tv) check to see if the whole screen is a solid blue, if it shows discolored areas around the screen then you might have to "demag" the screen. See if you can rent a demad coil from a tv shop and with tv on turn the coil in circular movements all over the front of screen till blue is solid.good luck!

No picture or sound mitsubishi 62525


Capacitor failure is the most likely scenario the FMT ans Signal PWB would cause the picture interference and the power pwb would cause the lamp light to turn red and give a 34 code when the device/ input and menu buttons are pressed in together and held for five seconds. That chassis has issues with every board in the chassis having failed capacitors you can get repair kits for the V26 chassis at the follwing link that come with instructions. Your model is the V26 chassis. Heres the link.

No picture, hear sound, television will shut off after a few seconds.


Lamp life is only a few thousand hours. Hopefully its only the lamp that made to noise. Don't turn on again until lamp is replaced.

Toshiba tz50v51 popping sound


Possible problems: * The TV set may be unplugged. * A fuse or circuit breaker may be blown or switched off. * The remote control unit (RCU) may be disabled. Solutions: * Make sure the TV/VCR are plugged in and the wall switch is on. * Check the fuse or circuit breaker. Test the outlet with a lamp. * Replace the RCU's batteries: if this fails exchange the unit.
