Question: how to hook up surround sound
Document: Pretty cheap for a 50" 1080p 3000:1 contrast t.v. right? Yeah, I had the same thoughts. Even with a few bad reviews (over the sound quality from the standard speakers, which were right on cue, you'd need a surround sound/external speaker setup) I still dove in after the "deal," however the phrase, "you get what you pay for," really fits well. I had this t.v.
I just got this Tv last night during black Friday.. I have had it now for 24+ hours.. sound is pretty good. but picture quality needs just a lil work.. But the price we pay and the 12 hours spent in the line at kmart.. F#$K  the picture! !I LOVE MY 50" TV..XOXO
We bought this TV in April and within a week the screen went crazy. Took it back to ABC and got a new one. Also bought the extended warranty. The picture on this TV just went out, so back to ABC. Ps, the sound for me, no matter how I adjust is annoying. We had to buy a sound bar to fix it. You get what you pay for.
We bought this TV November 23rd of 2012 and the picture does need some work but the more cords and the settings that you hook it up to makes the picture get better and better. We also connected our new Blue/Ray DVD and boy the picture is great!!!! I will however get the extended warranty because nothing is guarantied. Overall it is very much worth the price for getting a "50" inch!
went to program a new cable remote and the whole tv shut down...couldn't turn on/off red/blue yellow screen, called in cable tech thought it was cables fault but he verified it was tv broke..called company they walked me thru a reset but didn't work....so boxed it up and had to take back....got a better tv in the end...paid a little more
It took two external speaker system attempts to finally figure out how to turn off those nasty internal speakers as there's no option in the Settings. First attempt was to use the earphone jack but figured there must be a better way and then it dawned on me. I hooked up cables per diagram and then simply muted internal speakers from ProScan remote. Works like a charm.
If you are on a budget, but want a large flat screen, don't settle for this t.v. You'll want to spend the extra 100 bucks to get a better brand. (Proscan = R.C.A. by the way) If you want to get a good quality 50+" television, be prepared to spend no less than around 600$, because the quality under that isn't worth the money.
I purchased a Proscan PLCD5092A-B LCD television just 1-1/2 years ago. It worked great, but now will not turn on. The red light goes to green, but there is no picture. At first, I could unplug, plug back in and would get a picture after many tries.I called for service. The repairperson told me the main board needed to be replaced. The item costs less than $75.00.
I just want to correct the comment from a reviewer of this item that "Proscan = RCA", this is NOT true. Proscan is currently made and distributed by Curtis. Years ago, the Proscan name was used as RCA's step-up line of AV products.
I hate to throw out a TV that is only 1-1/2 years old.If I have to buy a new one, it will be a major brand such as Samsung, Vizio, or Sony.
Answer: Using RCA jacks, simply plug in the red and white males into the TV's "Audio Out" females in the rear of the TV, not in the side panel where you hook up gaming devices, etc. I then figured out through trial and error how to kill the internal speakers (look through the set-up menu from the ProScan remote and see if there's an audio control there). It may be as simple as moving the TV's volume to zero then only use the aftermarket sound systems volume controller. Good luck.
