I just had mine repaired for $600. The design of the set has an air flow problem that doesn't have enough flow to keep the dust from collecting on the circuit boards causing hot spots.The technician cleaned and checked the unit. It had a bad module (board)(T-75003031). This was replaced as well as the fan speed increased to move more air through the unit. It's working as usual so far, but I've only had it a week.

Toshiba 42hp66 has sound but no picture. I hear 2 clicks and Power led turns green when I turn it on, 1 click and led turns red when I turn it off, no picture at all.


Part of the power supply is in protect mode. There is most likely a short or something failed on one or more of the boards.
The service rep would swap out boards to locate the fault. Then he would leave the new board(s) in the set, and perform any necessary adjustments.
Take the set in for an estimate before approving repairs. There are many times these sets are not worth serving when they are out of warranty.

The picture on my 42" Toshiba HDTV has suddenly lost its brightness and clarity. Any ideas would be greatly appreciated.


This could be the backlight showing signs of death you might want to have that checked out.

If the unit is under warranty check this thing in for free repair if its not then go to the menu then adjust your brightness if it does not get brighter sounds like a backlight issue.


Thanks I hope this was Very Helpful for you!

Toshiba 42HP66, HDMI problems


Your Cable box might need to be reprogrammed. Call the cable company and they will drive you thru the steps to program it, this way you will get the channels. This process might take you 30-45 minutes.

Toshiba 42HP66 Picture fades in when turned on. After taking off the back  panel noticed the Zsus board had a bad fuse on the 180V Side. After replacing  the fuse the tv wont power on and the power supply...


To start, the module with the blown fuse will have to be replaced. The rest of the boards will have to be verified to know which other ones may have been the cause of the failure.

You will have to give the set out for factory service to have it working again.

Toshiba 42Hp66 No picture only sound


to test the zsus board check for a low resistance on the fuse to ground. sadly if the zsus is bad, the ysus and one or both of the driver boards is probably also bad. best to change all at once as a defective one can tacke out the others.
