Question about Toshiba 34HF84 34" TV

1 Answer

Flashes bright white randomly

My TV display randomly flashes bright white. Toshiba tech support told me to unplug the TV for at least 3 minutes to "reset the device" then try again. I have done so and this helped eliminate the flashing for approx 4 hours. The longer the TV is on the more persistent the flashing. Is there anything I can do, with basic soldering skills, outside of calling in a service tech?

Re: Flashes bright white randomly

Resolder the tv circuit in the power supply and the flyback area that will solve your problem as the symtoms are intermittent just some loose components due to consistent heat over the years.good luck.

Watching tv when the picture went black and now the green on light flashes for 30 times and turns off

A green flashing light for this model of TV indicates that the lamp cover is open on the TV.
  1. Unplug the power cable to the TV.
  2. Remove the 2 retaining screws on the lamp cover with a Phillips type screwdriver.
  3. Remove the lamp door completely from the TV.
  4. Remove the two retaining screws on the lamp case.
  5. Lift up the fixed wire handle of the lamp.
  6. Pull out the handle slowly and remove the lamp case.
  7. Insert the new lamp gently into the correct position. Make sure it is inserted correctly.
  8. Using a manual Phillips screwdriver (Do Not use an electric screwdiver), tighten the screws you removed in
    step 3.
  9. Replace the lamp cover and tighten the cover screws.
  10. Plug in the power cord and turn on the TV. After the initial warmup period (which may take up to several
    seconds for full picture brightness), the TV should operate normally.
If any of the following conditions exist, turn off the TV, unplug the power cord, and repeat steps 1–9 to ensure that the lamp unit and lamp unit
door are installed correctly:
  • The lamp indicator flashes green.
  • No picture
  • Dark picture
  • TV will not turn on
If, after repeating steps 1–10, the problem still exists, call Customer Service at 1-800-631-3811.

Toshiba cz32v51power light flashes, with no picture

That means that an internal error had been detected, and now the TV is on protection mode.

To start unplug the power cord for ten minutes, and see if the TV restart.

If it does not try leaving the set unplugged for longer, let say two hours.

If still no luck call the number listed on the user manual, as the TV has an internal fault, and must be repaired by a technician.

Picture has green tint on startup

Jar-Head, bad news, the picture tube has a mild short in the green cathode, tech can come out and try to restore it but it`s usually a futile attempt on sony tubes, sorry to be the bearer of bad news, BMW Rider

TV turns off by itself after being on for 60 seconds

Led blinking Three times means B+ over voltage protection (OVP), unit goes to the standby mode then displays the 3 blink fault. This is also a problem in the power supply circuit, check T603 and R672.
Hope this helps.

Try unplugging the set for about 2 minutes to reset the TV. The other possibility is a stuck button on the TV or a remote control near the set that is randomly sending out signals.

TV not coming on...

The same thing happened with my T.V. (although it is an RCA). The first time a repair man charged me $75.00 to fix. The next time we were told to just try unplugging it for a few minutes then plug back in...that worked. T.V. still sometimes does this, unplugging it fixes the problem
