Re: tv turned off
Its more than likely something in the standby power supply in order to be completely dead. I would suggest getting the service manual , and if you are wanting to repair it yourself. you can get free support to help you diagnose and repair the set for free when you purchase the manual from this link. They email the manuals and provide free support to enable you to figure out whats causing the problem and help by locating parts. Its a good service cause they have good service manuals and good support techs, http://servicemanuals.vstore.ca/

may be ur tvs lamp side have some problem. may be the lamp over heated and burned. just open its lamp cover ann check it.
also check its power supply input point(near fuse) there is an MOV (used for voltage surge protection) is burned or not. if there is any voltage surge it will get shorted and the fuse will blow off, protect the power supply for any further damage. check the fuse also. if found open then check the MOV. insert fuse only after replacing the MOV.
The TV circuitry is designed to protect from power surges. The fuse on the power supply may be blown, or the power supply itself could have taken a hit. I would try to check the fuse first and then if it turns back on... it did it's job!
You may have a blown fuse. Unplug the TV and remove the back. Look for a small fuse near where the power cord goes in.
If it is blown that may be the problem.
Use a magnifying glass to read the AMP rating.
replace the fuse and plug it in. If the fuse blows again you need expert repair services.
If the fuse doesn't blow then try to turn it on.
If it turns on then check the operation of the TV.
If the fuse blows again or the TV won't work correctly then you need expert repair service to fix your TV.
You may be able to have your household insurance pay if it is damaged by lightening or a power surge.
first things first- check the main power fuse; remove the 9 silver screws from the back of the unit, slide off the rear cover, and look at the main board right next to the power cord connection. There's a small, 6.3 amp fuse. Take a look at it; if it's blown... replace it.
It sounds as if you have a component that has changed value enough in value to cause a high current draw, but has not completely shorted out. this phrase from you "so I did a stupid thing and bypassed the internal fuse and it turned on and worked" Not as stupid as you would think because it confirms what I said above, the 6.3 amp fuse tells me that the current draw normally is about 3 amperes since the normal rule of thumb is to double the value of the current to select the type of fuse. a five amp fuse should as well as a 4 amp fuse (it's best and recommended to use the exact fuse type). Now back to your issue. I would suspect that a transformer in the power chain has developed a shorted winding, or a capacitor begun to develop a short or excessive absorption.
I would suggest that you have the set looked at by a qualified TV technician.
If you know what your doing the first step would be to check the fuses . They are not all glass fuses , some look like resistors but do not have the color bands . Most of the time you'll see them close to the transformer in the power supply in the secondary section . Some are green or yellow . Once you find them you''ll need either the schematic to trace where they go or follow there path when you have found the bad ones to see what section they go to . Sometimes it the convergence section or your picture tubes may be leaking on the signal board (which is on the left side) or possibly a bad flyback transformer . Some power supplys had loose connections by the secondary transformer or possible caps that buldge at the top of them by the flyback transformer . They were 100uf @ 250v caps . All of this could be tested with a volt-ohm meter and set should be unplugged . If your picture tubes are leaking you'll see with a flashlight a pool a coolant on the board . Sometimes it could be as small as 50 cent coin . Look at the metal shield suurounding the tubes then look below on the board . Hopefully this is not your problem . Good luck
