Spectra 50" TV has black screen, sound is ok, no picture at all Is there something I can do to fix this problem??
First and foremost, is it completely black or if you change the channels (like to an HDMI channel) do you see the display number in the corner? If the latter, then it's possible that the device(s) you have plugged into it, or the HDMI port went bad. Doubtful that is the problem, but I thought I would mention it first.
Try unplugging it and leaving it unplugged overnight. When you plug it back in do you have a picture? Probably not, but it's worth a try.
Beyond that, there are a couple of things that can be wrong:
Loose wiring - these TV's are really well known for loose wiring. If you feel competent enough to take the back off the TV, you can check for loose wiring
Bad capacitor's - these TV's also have really poor quality parts inside and a bad capacitor (or multiple bad capacitor's) can cause the same thing. Again, if you feel competent enough to take the back off the TV, you can look for bulging or leaking capacitors, they look sort of like a dripping or draining battery or bulging battery to someone not used to looking at them
Smacking the back of the TV - this one sounds weird, but sometimes smacking the backside of the TV will knock whatever came out of place back into place and it will start working again
Bad bulb - sometimes the bulb goes out, and a bulb is an inexpensive fix, but you'll need a TV repair shop to do the repair (unless you know something about TVs)
Worst case scenario - worst case scenario would be a burnt out board which can cost more than a new TV, especially of this brand
I don't recommend you open the TV unless you feel comfortable. It's high voltage back there and can result in injury if you don't know what you are doing. Additionally, there are some problems that can be fixed by watching You Tube videos it tells you how to diagnose the problem, what to purchase, etc. You might want to research such videos, if you feel comfortable doing the project yourself.
