Tv turns on but after 15 seconds you can not change any of the fuctions, no sound control or menu or imputes. I can change the channels with the cable box. It takes about 20 seconds to turn off. I have to be fast to change imputes or mute the sound. TV is two years old. When it worked TV would turn off in a second or two.

SOURCE: My TV has sound but No image!!!

a 42hp66 is a plasma set,, the y-sus or the z-sus circuit board has probably gone bad.. as these are expensive parts you might want to have a technician determine which one of the two is bad before ordering both of them

SOURCE: no sound on my Toshiba Regza 42HL167

Found this troubleshooting method on the www.Toshiba.com website. Q. My TV has a picture, but there is no audio?

1. Please check your connections and make sure if you are using COMPOSITE “yellow, white, and red cables”, SVIDEO,
with “white, and red” or Color Stream COMPONENT “green, blue, red, white and red cables,” that the white
and red cables which are used for audio are plugged in securely into the same inputs as the video.
If your connections are secure, the station may have broadcast difficulties. Try a different channel.
2. If you are using the coax cable from the wall, press the “ENTER” button on the middle of the remote. If the
information provided shows that you have SAP selected we will need to change it to STEREO or MONO. To do
this, we will need to press the “MENU” button, and use the RIGHT or LEFT arrow keys to highlight the AUDIO
menu. Next we will need to use the DOWN arrow to select AUDIO SETUP press “ENTER” and then arrow down to
MTS and use the RIGHT arrow to select stereo.
3. If you have a cable box or satellite receiver, please make sure the TV’s volume, as well as the box’s, volume is
turned up sufficiently.
4. The station may have broadcast difficulties. Try another channel.
5. The sound may be muted. Press VOLUME.
6. If you still have problems after following these steps please contact Customer Solutions at 1800-631-3811 Monday
through Friday 8am to 7pm CST. The Toshiba customer service number is 1-800-631-3811. I hope this helps you with your problem.

SOURCE: White/Grey screen with non-HD channels

I removed the HDMI cable and connected with component video and rca audio. No more white screen.

Picture quality looks good. I don't know if it's as good as HDMI, but then I don't need to reboot the TV three times to get to teh on-demand menu... Grrrrr....

I am trying to contact Toshiba on this as well. I have seen several reports of this problem on the web.

SOURCE: you turn on the TV, the green light flashes 3

have you had the freeview board off and used tv with it not on. sometimes the built in free view board can fail and use the processor speed up. so no menu etc also will affect the inputs..
