toshiba has no power no red light

If not still under warranty or covered by insurance, disconnect the power from the TV and then remove the TV back cover and visually inspect the power board (board where the power cord connects to) for any obvious damage such as burnt out or heat stressed components or blown or bulging capacitors etc.

If you do find any damage or you're not sure post some close up images so that others can see.

Here's how to do this.

Hi @nos7114 ,

Green light but no picture or anything else I assume?

Could be the power board but I didn’t notice anything untoward.

Couldn’t magnify it enough without blurring to see if there was any info printed on it such as STBY near a connector going to the mainboard.

If there is it should have +5V DC on it when in standby mode and the red light should be on. So given that it originally wasn’t on and now it is but nothing is showing the power board is still the first to check out.

I found the service manual for the TV so that should be a help as it should have schematics etc. allowing you to check and test the power board

However when I downloaded it that it would not open due to a Zeus Engine missing error.

Found this webpage, scroll down to 3rd post to read about Zeus Engine error and the downloads required etc so that you can view the service manual.

You may have to do this if you want to use the service manual.

Alternatively you could search online for (insert power board “board” number) schematic and check if there is one available

It is fortunate that this manual is online as usually Toshiba documentation is not publicly available

Have you verified that the power outlet that the TV is connected to is working OK, by plugging another appliance e.g. a hair dryer into it to prove that it works?

Was there a storm or power outage just before the TV stopped working?

If the TV is no longer covered by the manufacturer's warranty, disconnect the power from the TV and remove the back cover from the TV and inspect the power board (the board where the power cord connects to) for any obvious damage to the components or if there is a fuse mounted on the board whether it is still OK etc.

If there is some component damage or even if you're not sure, post some images back here in a new question. Also provide some information such as TV make and model number, fault symptoms e.g. no indication of any power at all to the TV and any other relevant information e.g. power outages or storm yes or no etc

Not quite with you.

Where is the media logo?

I've clicked on most things at the bottom of the page and saw nothing that looks like it.

can't you just upload them again?
