Question about Toshiba 53H71 53 in. Rear Projection Television

1 Answer

Flashing Power Light

I moved three weeks ago. (Professional Movers). My Toshiba was working great until before the move. One other thing was when we first hooked it up at the new home the color was off. I thought this might have been from the difference of switching from Direct Tv to Comcast cable. But it would change after it was set. Then "WHAM" no picture. I had video and then the signal went out and the red power light started flashing on & off. Could not turn the unit off with remote of power switch. Unplugged and left it unplugged for about 15 min. Same problem when I plugged it back in. Could the move 350 mile have caused this? Also what kind of cost would I be looking at. This set is 4 yrs old.

    Our 43HX71 Toshiba TV suddenly stopped working 4 days ago, there is no picture, but the on switch blinks continuously, the only way to stop it from blinking is to unplug the power cord. This TV is about 7 years old.
    Thanks in advance for any help.
