The tv comes on but the picture tube has gone bad. at first if i warmed the tv up it eventually came on. the all at once the tube went out completely. i need to find a repair place where i can find an buy a new picture tube in columbus, ohio

If this is an LCD TV, show a flash light on the screen from a safe distance. If you can see picture, it means the backlights have gone off and the TV might need servicing.

Sounds like the convergence has failed. This video gives more details

The picture tubes are warn out or the deflection circuit is failing. The power supply is struggling to fire them up. Takes a lot of power.
Some TV shops have the know how to replace the tubes. About $1000 parts and labor.

I had the 65" version of that TV. Loved it, unfortunately it went bad as well. It sounds like the red tube went bad. The tube itself might sell for $400 plus. The installation will take several hours with the alignments which will need to be done. Then after all that you will start to have to worry about the other tubes starting to deteriorate. If there is any red in the picture then the tube is most likely the problem. At tat point I would say buy a new TV. The best bang for the buck if you want size and have the space for it would be the new Samsung or Mitsubishi DLP's. I just installed one at customers house. The 60" Mitsubishi is 1400 at Best Buy Good Luck Rob

This is a common problem with this model and a fairly easy fix. You can get parts and a photo instruction guide from www.TvRepairKits.com.

Hope this helps

Assuming this is a TV with a picture tube and not plasma or LCD; I'm afraid that your picture tube is dying on you one electron gun at a time. From what you said your green electron gun is almost totally dead and the two remaining blue & green guns aren't far behind. Eventually you'll have no picture at all and I would estimate that to be about 6 more months but whatever the time eventually it will go totally black. These blackout periods will get longer and longer. The only way to fix your problem is a new picture tube but my will probably find it less expensive to just get a brand new TV set.

humm from the sound of a loud pop that would tell me you have a high voltatge problem. at the shop i have seen when i replaced tubes in this set that when the tubes are unbalenced (screen voltages) then sound will come up with no picture. then the tubes warm up and the picture comes up. this is an idication that one of the tubes have gone bad. and now that it has completly failed i suspect it has taken the horizontal ouput transistor and possilby flyback tranforner, NOW what all that tech talk means? not good im sorry. but in my opion this set is not good. these set cost about 800 new at your local walmart. We charge at my shop bout 600 to 700 for such a repair..of course u may get a tech to look at it and find something simple. but i feel this is the case if you have any more qestion feel free to email me or ask again here [email protected]

I believe you either have a problem with your Power Supply inside your TV from a defective component in the circuit or you have a problem with the Picture Tube on your TV. I don't recommend you working on TV's by yourself unless you know what you're doing since you can get badly shocked. You need to discharge the Picture Tube on the TV before you work down any further. If you don't know what you're doing then you should get someone that knows what they're doing to work on your TV.

sorry bad news tubes gone.

Most likely cause would be a loose solder connection that expands as the set warms up until it no longer makes a connection. You may get the blue to come and go by hitting the side of the cabinet after the set is warmed up awhile. (don't hurt your hand doing this, and don't keep doing it to "fix" the set. The connection will have to be located and repaired). Otherwise, there could be a component going bad, including the blue picture tube.
