Hello all, not sure if this is the correct area so sorry if its not.

We have a Sony CRT 27" TV & since my dad has retired this tv has been getting more of a work out so to say. Anyways I come down this morning and it wont turn on. My dad said it was turned on then just turned off for no reason. He did not hear any noise coming from the tv either apparently. also checked for a burning smell but there is none.

So I tried turning it on from the controller and on the buttons on the front of the tv but nothing. I tried unplugging it from the power extension and directly into the wall but still wont turn on.

I had to leave to go to school but I left it unplugged and will try again when I get home. Just wondering if anybody has any suggestions to see if I can find out whats wrong with it? Anything to look for?

Thanks

If the AC is there and it still will not turn on, then it will be necessary to dive inside. If you are not comfortable with that then it is time for a trip to the repair shop (or a new TV).

Re: TV Problem

I'm pretty sure the jack is working since the radio was plugged into the same one and our vcr and all had power.

I dont mind opening it up and so on. I work on computers all the time. But is it possible to get a bad shock from it even if its unplugged?

also what should I look for?
If its to expensive to fix then we will be buying a new one.

Thanks

Chances are the horizontal output transistor is blown.

Easy fix if you know what you are doing.

Dangerous, possibly fatal task if you don't.

CRT's can store a large amount of energy for days even weeks after a TV has been sitting unplugged. A 27 inch this voltage could be in the range of 25-30KV, yes 30,000 volts

So if you do not know what you are doing then take it to a shop.

I have a TV that gives me the "GSOD" (green screen) once and a while. Just unplugging it and plugging it back in fixes it for months. (Now I have a power strip so it is painless) You have tried that, so it is starting to look like some part has gone bad.

There is a good chance that it needs professional help. These days it really is hard to justify fixing a 27 inch set. With all the dust that I see in them, its a wonder more don't break. For a couple hundred you can probably replace it, or better yet, look in a yard sale or a wanted-for sale publication. With so many folks buying new, 27 inch TVs are getting tossed out and since they are heavy, folks just want them gone.

My Sharp had a transistor close to this

Sounds like either a fuse(board mounted) or a relay/switching transistor died.
I snagged a nice Sharp 30" TV one time that "died"... replaced the switching transistor... still working today!

Usually a semi-big transistor near where power connects to the board.

Also, YES! TVs can zap you!
Anywhere from 12,000V to 30,000V!

BE CAREFUL!!!
