There's a good chance you have failing electrolytic capacitors either in the power section or the inverter section or both.
Any caps in these sections that look bulged at the top, or bulged/leaking at the bottom need to be replaced.
If you repeatedly turn it off and on, eventually it'll probably stay on, but every time you turn it off, the TV will get harder and harder to start up until one day it just won't.
Sometimes you have to do the opposite to start it up and unplug it for some time and then try again.

If you aren't tech savvy, don't worry, read the rest of this solution and watch the videos.

If you are handy with a soldering iron and can identify the power supply and inverter / FM section for the backlights, an inexpensive handful of capacitors will likely fix you right up.
Match the capacitance on the capacitors. Go over voltage if you can, and still have them fit.
IE - it's not a bad idea to replace a 10V cap with a 16V or 25V or even a 50V, but don't replace a 680uF cap with a 500uF or a 1000uF (unless you are positive it's only doing ripple filtering, and even then, you should go OVER, not under the uF rating).

Most of the caps that go are 10V 1000uF or 3300uF.

I found some great videos of the procedure (for many Samsungs with the same issue) on youtube.

As you can see, this issue spans plasma TVs, as well as large and small LCD TVs and monitors.
The parts are cheap, and skill required is minimal.

My TV is almost 5 years old. Barely used more


Howdy,
Sounds like the TV has lost the VIDEO and only has color. Make sure all the cables are secure and good. 2) Reset the TV by unplugging the TV or any BOX you have attached to TV. Unplug both from a/c for 3-5 minutes, plug back in and turn both on.
If no fix. Go to service Company that is Authorized and get an estimate, possible cost $450.00 +. Too many areas of concern to help you with particulars.

Good Luck, Big Irish.

Have a hitachi 51f59a rear projection set that has no video in antenna, video 1,2,3,4,5. Have tried dvd and cable. the OSD works and displays on the screen. Have tried unplugging and the G2 screen...


I have owned this model for 4 years now. 2 years ago this same thing happened to me. I think the repair man said the transformer went out and he replaced that. It has happened to me again so I will try and do this myself, and let you know if I succeed. This TV has been terrible, I will never buy hitachi again. If you ever use an hdmi cable the tv does very weird things like changes color or distorts for about 30 secs then goes back to normal. P.O.S.

Hitachi has had problems with their light engines. Very expensive. Contact Hitachi as they may give you consideration even if this is out of warranty.

TV will not turn off with remote or manual have to unplugged


I suspect the unit might need service. If it were only the remote, new batteries would, of course, be in order. But that part about the manual power button being ineffective suggests something else is affecting the set. Sorry.
