Volume is too low on my old Sony Trinitron KV-27S45
A few years ago, when you turned on the tv it would gradually gain in volume until you manually adjusted it to a lower-setting. Now, it doesn't raise in volume anymore as you turn it on. It is just so low, only about 3 stations come in any where near audible. What could the issue be? Can i fix it with out parts? If i need parts, would it be less expensive to just purchase a new tv?
Thanks for any help!

1. Turn the main and monitor volumes all the way down (off). Plug a cd player into channel 9/10 and play a track of music of your liking. With the main/monitor volumes still off, adjust the gain on 9/10 until the clip light turns on, then back it down until the clip light just turns off. Put the channel volume at 12 o' clock.
2. With the music still playing, turn up the mains to the desired listening level first, and then adjust the graphic eq until the music sounds good in the room. Remember or mark the position of the volume control. Do not use the channel eq on 9/10 for music that has been mastered properly, leave the eq flat. Once this step is completed then you have now set the main eq.
3. Repeat the same for monitors. Turn off the main volume and then bring up the monitor main volume to the desired level first, then set eq. Now your monitor eq is set properly. Remember or mark the position of the monitor volume.
4. Set up microphone - plug a mic into channel 1 with volume all the way down. Speak or sing into the microphone and adjust the GAIN until you see the clip light, then back down a litttle on the gain. Put the monitor and main volumes back up to the mark from step 2. Now adjust the volume and monitor send on the mic channel to the desired loudness first before adjusting the mic channel eq. Use subtractive eq method to minimize distortion and feedback. ...i.e. if the mic is bassy then turn down the lows, do not ADD highs. If the mic needs bass, turn down the highs.
low pass of course set the crossover around 80Hz. Then turn the bass down to around 35% on headunit and the volume all the way up on your head unit just below distortion. slowly turn the amp gain up until you start to hear distortion, then turn it back down until it's completely gone. Then, lower the gain just a little more to make sure you keep out the distortion on all songs. From here you should be good. If the gain is still to high. The adjust to your taste. Just don't move the bass up on the headunit or the gain past your distortion point.
Without knowing the model number it's hard to say. However, it's not uncommon to have a defective switch on the actual TV itself. Try pressing the switches on the TV and make sure that they 'snap' in and back out when they are pressed.
The level control controls the input level coming from your head unit (receiver) to the amp.
Your Sony users manual is a little vague on how to best adjust the level and other controls.
Here is one method that some installers use and works well with most amps.
Most 10" subs sound best between about 80-100hz and below, so start out by setting the LPF at about 80hz. The HPF will not be used. Next turn the bass boost and gain all the way down. Turn on the radio and set all tone controls, bass, midrange, treble to flat, usually "0" on most head units. Turn the volume up to approximately 3/4 volume level or just until you begin to hear distortion. Now, back the volume down until the distortion is gone. Next turn up the gain control on the amp until you hear the subs start to distort then back the gain down until the distortion disappears. Next turn the bass boost up again until the subs begin to distort, then either back the bass boost down or back the gain down until the distortion is gone. You may need to play around with the bass boost and gain controls to get exactly the sound you prefer.
Use the satellite receiver remote control to adjust the volume first. The receiver itself offers volume control and you probably have that turned down. Then you are trying to raise it with the volume control on the TV. This is raising the TV volume, but there isn't much sound there in the first place. Use the receiver remote, and you will probably see a volume bar. At some point it might say something like "best stereo" or a star might appear. If that happens leave the volume set there, otherwise just raise it all the way. Then control the volume with the TV remote, or program the DirecTV remote for your brand of TV, and the volume button should control the TV then.
ADjust your Gain setting to limit just enough so the amp does not go into Protect mode. Turn your Gain all the way down, then crank up the bass from your system. GRadually turn up the gain until you trip on protect. Turn the gain back a notch and your set for no more protect.
