My Toshiba won't turn on, all my cords are plugged in correctly. The power just won't turn on, I've tried using the remote and the tv buttons but nothing is turning on. No image, no nothing. The green light that shows up when the power turns on won't light up.
I see so many here with no sound/nopicture issues:
ISSUES:
1. IF sound main fuse/s are good.
2. If no power or standby check main fuse, standby power supply and any signsof damage you can see---burnt parts etc.
3. almost all these sets the troubleshooting involves checking voltages on the main power board to narrow down theproblem.
4. Be safe and if you do not know what you are doing don't open the set.
Answers to issues:
1. RE:fuses---if a blown fuse is found get a good replacement(not the genericones like Radio Shack). Many fuses are special even aside from amperage--Don'tput a higher rated amperage fuse in the set for any reason.
2. RE: power supply in set: if total dead aside from main fuse the set uses astandby power supply that runs 7/24 and a main supply (some are combined andsome not.
Here aside from checking fuses you want to examine all the filter caps on thepower/standby to see if any are puffed up or buldged up in some fashion--Iattach a photo of a good one---top should be silver metal and PERFECTLY flatand have no brown material coming out on top or bottom.
What happens in the standby area is they use caps with too low a voltage rating(saves money) which causes them to fail in a year or two---the standby runs7/24 and the heat dries out the caps and they fail.
3. Trouble shooting consists of the above and then at some point you have to buyand try a board to see if it fixes it or not.
4. Safety first--no TV set is worth getting injured or even killed over.If set is opened at least look for puffed up and bad caps like in thisphoto.

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

yes call the tech and have the power board replaced. In future have the TV plugged into an anti surge board to protect it ( and you from expensive repair.) I suspect you will need a new power supply fitted

Down load this firmware file p/n 2007SEN069 from this address http://www.tacp.toshiba.com/customersupport/model_firmware.asp?model=26hl67. The instructions are here also. Un zip to a blank sd card. I'm not sure if the set will boot to the card or not.
I finally got the tv to boot by constantly plugging in the a/c power and unplugging the power until it filally booted and was able to turn the set on.
Remove the sd slot cover from the lower right rear of the set, and insert the sd card with the unzipped firmware. Monitor the screen and follow instructions. Do not remove the card until the set powers off.
This fixed mine, hope others benefit from this repair.
