Question about Toshiba 43H70 43" Rear Projection Television
I have a Toshiba 43" rear pro tv, and it seems now to take a while for the picture to come on. Sometimes it will turn on quick and other times it will take ages, I can hear that the tubes are still going just no picture or blue screen of any sort. Once it comes on its usually sweet as, sometimes will flicker or roll a bit. Any suggestions as to what it could be is much appreciated.

It sounds like your switching power supply or you High Voltage power supply has malfunctioned. These sections control all power to the TV and can produce the situation you are describing. If you do not have a background in electronics, I would suggest that you have a TV repairperson come over and check your TV out.
I say this because there are voltages in a TV set that can kill, so caution is needed.
I hope this helps
