Problem with Samsung TV

I have a Samsung TV that is having problems. It is a HDTV CRT model TXN3071WHFXXAA. We have had it for just over 3 years with no problems. Last night my wife was watching a show and she said that she suddenly saw a bright white light in the center of the screen like a hole and then everything around that came in like a vacuum and went black. After that the TV would not turn on.

This morning it did come on and seemed to work well for ~5 minutes and then did the same thing.

I would assume that the tube has gone bad but I really have no idea... and I'd like to have a little better idea if that is the problem and what repair might cost (SW Ohio) before calling someone.

Any help would be greatly appreciated.

Matt

The tube isn't bad. Just how much experience do you have repairing tv sets?

TV sets = little to none.

Not too bad with electronics to an extent. Building computers and home wiring, etc...

II am heartened to hear that it is possibly not the tube..

I'll assume it's a power supply problem. Several ways the unexperienced tinker can suffer injury or even death. Your candid reply stating you have little to no experience in repairing tv sets can edict the only response I have and that is to get the set to a qualified tech. Sorry if that isn't the answer you sought.

There are step by step methods us techs use to diagnose. Some have been garnered over years of experience. I use the flow chart method of "if this is ok then check this, if that's ok then check this, if not, go here" I understand and support your want for self repair but ventures like this rarely turn out favorable. And I don't support a novice poking around inside a set that has the real life potential to harm or kill you. If you like self repair, take some schooling on it. Don't try to learn with hazards that all sets have.

No, I'm cool with that. I read up a bit on monitors and death when I was building my arcade machine.. not something I want to chance.

I am just wondering a range that fixing the power supply might cost.

we don't know *for sure* that it is the power supply. The fact that it works for a time suggests to me bad soldering, possibly in the line stage or power supply, or a component whose value drifts with warmup. In any case it will need to be taken in to a service centre for investigation and diagnosis. May be worth paying for that, so you know the tech opens up the set and hence gives you a realistic idea of the problem . (those with free estimates rarely do this!) This charge is then usually discounted off the cost of repair should you go ahead. As for cost, that will depend on the extent of the problem. That is not possible to accurately say with internet guesswork, as nobody here has actually *seen* the tv. If the set gave a good picture and is within the last 8-10 or so years, I'd say spend about a third, or a little more, of the cost of a new similar quality set. good luck
