    Just wating the game and all of a sudden .....CLICK..... the power light on the front it blinking and no pic, and no sound

  • originaljrs Dec 19, 2007

    Toshiba 50H81... TV worked fine. Shut it off and then 30 minutes later attempted to turn on again. Relays click as if it wants to power, but after 10-20 seconds, no pic and power light on the front of the unit flashs. :-(



    Read something in a Tech Bulletin that cold solder joints could lead to blown fuse. The joints are on the bottom side of the power circut board and are the negative terminals C809 and C810 (I believe). Checked these joints, but they looked good. The one fuse I found right by the AC cord also looked good (which makes sense since the unit does actually get power; it just doesn't fire the projectors).



    Any more thoughts?

Did you check the supply fuses to the convergence ICs? Did you check the output resistors
other wise i would replace the convergence ic first.

Sounds like your lamp has failed. May not be physically blown but the 5 blink code indicates either the lamp or ballast has failed. Normally its the lamp. Good Luck!

No picture and the power light blinks


A red blinking light could mean that the lamp timer is at it's limit and it is time to change the lamp. You will also have to reset the lamp timer by pushing and holding down 2-3 buttons on the tv or remote. Refer to your user guide for the proper way to reset and or change your lamp.

Red power light continuously blinking. no picture no sound.


It could be the lamp went out and needs replacement. The Toshiba website states when this happens to unplug the televison for 10 minutes then plug back in. If that does not work then try another power outlet. If that does not work then call for service
