Question about Proscan 26LB30QD 26 in. LCD HDTV

Poor sound quality

I have a digital cable box; my old tv had great sound. The proscan has a slight hum constantly and the audio shows (and sounds) mono. I cannot determing how to turn on stereo on; and how to eliminate the hum.

    I have the same problem with the speakers emitting an extremely annoying hum.

  • thomascim Feb 24, 2009

    Hi, I am having the same problem on a brand new 2 day old proscan 26lb30qd.

    To go into a little bit more detail: when the tv has been off for an hour or so and is turned on the hum is not present immediately. After 10-11 minutes the hum starts.

    The hum is evident when connected via coax and composite connections and when using the in-built DVD player (with and without a disc present). Also I tested the TV on different power outlets around the house.

    Changing speaker balance or eq settings has no effect nor does changing any picture settings.

    The hum keeps on humming.

Hi, I sent an email regarding the issue to OnCorpus (the company who makes ProScan)

This is what I got back:

Thomas,
Follow these steps to correct humming issue:
1. Turn tv on
2. Input mode should be tv
3. Turn volume to zero
4. With remote enter 9 8 7 6
5. A menu will appear on left side
6. Arrow down to backlight and with right arrow key move number from 81 to 83, press menu button twice,
7. Turn up volume and listen if hum is gone.

I can't confirm if this works at this moment since I don't have access to my TV.

LG 55LS4500 55 in. TV has sound through speakers, no audio except a hum from headphones and the optical digital to analog output fiber lights up but no sound output What board is bad?


Hi Louis,
The audio circuitry is located in the main board. Try unplugging the TV for a while and try again if the audio comes back.
I would suggest to check all your settings in the audio section first and if everything seems OK then the main board should be replaced.

I have an RCA proscan tv, CRT type. My sound has to be turned all the way up to hear it. There is also a low hum whether the sound is up or down and does not change volumn, no matter if the sound is


The ctc169 was the workhorse of the RCA line being used in over 300 models----sounds like a possible audio output circuit---a lot of parts are no longer available and I would be careful having a shop fix a set this old.

YOU "might" be able to get around this with a surround sound system used with a cable box.

TV Hookup


The TV is NOT a source of high quality sound.

For the best serious audio I would recommend drawing the audio-only digital feed from the Cable Box via its highest quality audio output. Then turn the TV's volume down. Also run the vanilla RCA stereo audio pair from the cable box to the TV in case you just want to check the weather.

Try moving the audio and video cables to a different input.
Or the cables maybe bad. That's what happen to me.

Proscan tv surround sound hook up


This depends on whether you have digital cable box or not. If you have a Digi Cable Box look for the red/white RCA output and connect this via RCA cable to the Red/White Audio input on your surround.

If just Basic Cable look for a red/white audio output on the back of your televison. connect this to the Red/white in on your surround. Could be called tv in or auxillary.

I want to connect the Audio from tv to Surrounding audio system


For connections of audio, so that you can hear all tv audio through the
surround system, connect either an optical audio cable or red & white
analog audio cables from the tv to the home theater. If you are using
optical audio, there is a plug on back of tv labeled for digital audio
output and an input on the surround sound system. If you plan on using
analog red and white, use the PROG OUT red and white output jacks on the
back of the tv to the AUX input on the home theater.

For video connections, to get HD you will need to be using either HDMI or
Component cables. HDMI is the cable that will provided 1080p signal (the
best HD signal), but if the source does not output 1080p, then your tv
will not display 1080p. Most cable boxes output at 1080i or 720p when on
HD stations. This signal still provides great picture quality, but HDMI is
not needed to get these HD signals. You can use component cables for your
cable box and the DVD player output to the tv for video. HDMI might give
you a slightly better picture quality but the signal will be the same.

To make the connection, you will want to connect from the cable box to the
tv (component or hdmi). Also from the home theater system to the tv using
hdmi or the video cables from component (red, blue, & green cables).

We hope this information is helpful to you.

Thank You,

No surround sound for TV


There are a few possibilities.
1)You can connect a red and white AV cable (or the red and white portion of a red, white and yellow cable) from the TV Audio OUTPUT to the "Audio In/TV" portion of the HTS (NOTE: Many TV's do not have an Audio OUTPUT).
2)You can connect a red and white AV cable (or the red and white portion of a red, white and yellow cable) from the Audio OUTPUT of your cable or satellite box to the "Audio In/TV" portion of the HTS.
Note: Using a red and white cable may not give you sound on all 5 speakers.
3)Get a digital audio or SPDIF cable and run it from the TV, Cable or Satellite Box's Digital Audio OUT to the "DIGITAL IN" of the HTS. This will give you the best sound quality. When using this (or any of the other) type of connection, press SURR until you get sound from all 5 speakers.
Also, the manual can be obtained from www.usasupport.philips.com

Proscan to Bang and Olauffson sound system


FDirstly, you should not connect your TV to a Sound System. If you desire to listen to your Broadcast TV , and enhance the listening experience,I suggest you use the Audio L & R outputs of your Cable Box to your Sound System AUX IN , and Video Out to the TV's Video IN socket. Then you will recieve a better picture and a enhanced sound quality. But just directly connecting the TV's Audio Out to the Sound System will make scarcely any difference.
