Toshiba 44NHM84 won't turn on

After having this tv for a little over a year in my bedroom and was used sparingly, it would try to turn on, making a buzzing noise twice about 5 seconds apart and then shutting off. I did the "fonzie bang" and it worked fine. I left the set on for 6 months until it happened again. The bang didn't work this time. Thanks for your help.

Usualy these problems are due to solder evaporating under the heat of the component.If you are a competent technician,by opening the tv set and by looking closely on the solder part of the board,
you should see a few that are not as shiny as the other, or look like a donut around the pin.these should be redone.those failiure are around the components that heat up:voltage reg,h-v reg and the
resistor around them.
good luck

Toshiba TV won't turn on


Toshiba? Suspect that if it uses a Lamp for brightness (a model number would help) it may have failed----customer replaceable and if remove look to see it is not shattered inside--2 year, 2000 hour life is normal.

We have a red light flashing on the front of the tv.It shut off and we don't know how to turn it back on.


A red flahing light is sometimes a Standby Mode. Does the power button on the remote turn it on.Sometimes the remote has multi funtions and you need to select TV for it to work.Try using the Power Button on the TV.Good Luck.
