Question
I have a 60 inch Sony projection tv  that suddenly stops working no picture and no sound and I can smell something burning when we open it the smoke is coming from the mother board. is it worth fixing? its only 6 years old.

Answer
Depends on the model.  Mostly, a good Sony RPTV should be good for 12 to 15 years of service.  However, some models are better than others.

Also,  it is a matter of cost and expected future failures.  If the model has a history of board failures it may not be a good investment. You can do a google search and read through some of the forum comments on your model and get an idea of it.

Consumer Reports recommends that when a big screen set gets over 5 or 6 years of age the better strategy is to invest in a new model. I agree with that general rule.  Yours is a borderline case, isn't it?

It will require a physical investigation to determine the cause of smoke and some voltage checks to zero in on the culprit, for sure. A new board could cost as much as $300 to $400.  And, if the new board goes out again soon thereafter you are looking at another repair job.

So, you have a difficult decision to make.  Sorry, but under the circumstances there is no clear answer.  It is probably worth getting a good tech in to look it over and make a diagnosis; then make a decision based on reliable data.

Hope this helps.
