Trying to help my girlfriend out. She has a 46" Sony Bravia KDL series TV that is about four or five years old and out of nowhere the TV will not turn on. I have checked all of the power cords, unplugged and replugged the cords, double checked the circuit breaker and still no power. There are no lights flashing, just plain dead. The TV was working fine 12 hours ago.

Is it time for a new TV already or can these things be fixed?

Maybe a blown fuse or capacitor inside ... of course it can be fixed, for a price.
Google your TV model number and there maybe a repair video for it if you dare to diy.

I've looked it up online, looks like a fairly common problem among Sony's. Signs point to blown power module. Have a call into a repair shop to see what the damage will be.

It's not hard to replace the module (it's just a circuit board):

I'm all thumbs and don't want to be responsible for screwing it up. Looks like an easy repair, so hope it's good news from the repairman.

You can use a screw driver, can't you? That's all this will need once you ordered the right part.
The gf doesn't need to know that it was simple and you can earn lots of man-points from her by simply pretending it was hard to figure out ... just hem and haw alot while taking apart the TV and point out make-believe components to her: "Ah, there's the fluidic capacitron which sends a signal to the loader. Now it's making sense!"

If the TV is under any kind of warranty, I wouldn't recommend cracking it open yourself. Assuming it's not, then my desire to do a repair like that would be based on how willing I was to replace the TV if I messed it up. If the TV was four years old and you were thinking about upgrading anyway and it had this problem, then yeah, take a crack at it. If not, it's probably better left to the "experts" if you're not comfortable.

With the speed at which technology improves, 4-5 years seems to be a decent longevity for a TV. I would bet that a repairman will charge you close to $100 just to diagnose the problem, then parts and labor to fix it. I'm sure you will find the same size TV with better features is a lot less than was paid for it initially. Just don't consider Westinghouse, their 46" TVs did this after 2 weeks-1 year, due to faulty Chinese workmanship soldering the power supply which would short and destroy the whole TV.

For $100 had the repair guy come over and take a look at it. Was a faulty resistor of some sort, so he pulled it out and soldered in a new one. Lot cheaper than buying a new one. What was most surprising is finding out that there are still TV repairmen out there and that they make house calls.

My 60 inch Bravia wont turn on. When I hit the power button the red light goes out and the green doesn't come on as it normally should. (no lights at all) It doesn't matter if I hit the power button on the tv or the remote, nothing happens and the tv wont start.
HOWEVER, I have discovered that if i turn it off at the wall, wait 5 mins then turn it back on at the wall the tv will come to life as it normally should. If I turn it off with the remote and then back on after a matter of seconds it will be fine but if I turn it off for more than a few minutes the problem returns and I have to turn off at the wall and wait 5 again.
So I can work around this problem but it's annoying having to go behind the tv to the "hard to reach" socket every time I want to watch tv.
Does anyone know what's going on here and if it's expensive to fix. I'd like to avoid having to lug this huge tv around to the repair shops.
