The tv went black we can hear what is on the tv we just can not see it, we have repaired it several years ago and it was the transistors. the color was either all green or bubbly in places. could i possibly need a new picture tube or should i trash this one since it is over 10 yrs old and get a new one?

Re: our screen went black no picture only sound
Try a hard restart, which simply means unplugging the power cord of the TV, and replugging it after 4 hours have passed. If this does not bring the picture back, then you should consider buying a new TV. The costs of a repair ( labor and parts) might exceed the cost of a new TV. Your 10 year old TV has served you well, and has exceeded the average life expectancy of 5 years. May it rest in peace in TV heaven.

sounds like the sceen is dead, if you are receiving nothing on screen, then it sounds like either a component and/or screen is gone... however, check the tv input to make sure it wasnt acidentally switched to an input channel with nothing selected... if that does not work, call local tv repair or mfg customer service tech. if under warranty, have repaired or replaced. without physically seeing tv, it is hard to diagnose issue outside of information given. could be simple board replacement or could be screen.. but check input first, if a dvd player plays, then it could be just component or input on wrong selection
This tv have a colors wheel,hear loud motor noises,humming noises,squiling or grinding noises,have pictures black and white.All these causes are by the colors wheel is worn out, warp rubbing against it motor or fiber plastic glass briddle about to brake aparts.Don't turn this tv on anymore until,u change the colors wheel or u will damage the projection engine.The colors wheel are hard to change for amatur and hobiest.Because involved taking out many machanical parts,before even can come to the colors wheel to take out and change it.The best course to to hire a Tv Tech.to do this job.The price colors wheel part and labors.Awhile back was about $500-550,now??
This indicates a problem in the power supply either the low voltage switching supply or the High voltage power supply. The sounds you hear is the shutdown circuit activating, I would not suggest that you try to repair this problem because of the dangers involved. I would suggest that you take it to a qualified TV repair shop. This problem should not cost you much, however it is the best choice for the problem you described.
I have had my Sony KV-32FV15 for about 2 years now and nothing has ever gone wrong(even going through several moves.) I recently moved again and when I plugged in the TV, you can hear the sound perfectly but the screen just stays black. You can not even hear the squeal that the TV makes when comming on. Is there anything that I should initially look at to troubleshoot. I cannot afford at this time the $250 fee to repair my TV. I look forward to your input and hopefully I can get this TV working again.
Sounds like you have lost video somewhere in the video circuits. Possibly the picture tube could have gone bad or lost filiament voltage.
You can check to see if you have high voltage by holding your bare arm close to the screen. The hairs will stand up if you have high voltage. Absence of high voltage will also cause a black screen,but the sound might not work either since on some sets the power for the sound is supplied from the same circuit as
the high voltage.
The good thing is you see something in the screen,with age the set has developed loose conections in a few different places,my suggesion is to call professional for service now and the repair will not as expensive,if the picture quality is good is worth it.
