Question about Sony KP-46WT520 46" Rear Projection HDTV-Ready Television

1 Answer

Screen and volume problem

I have been having a problem with my Sony Wega recently. The volume freezes at a certain level and although the indicator moves the volume remains constant. The only way to fix is to turn the tv off and back on. Now when I turn it off and then back on I get a single horizontal blue line through the middle of the screen and no sound. Will do that several times before I can actually get the picture and sounds back. Any ideas?

My freezer has a different code number;ZFT710FW.I put quite a lot of food into the freezer yesterday and the alarm now keeps sounding,I have put the temperature up but the red light is still flashing...


Red Alarm Indicator Light
Under normal operating conditions, the internal temperature of the freezer will ensure the long-term conservation of the stored food. When such temperature rises above a certain level (-12 °C), the appliance will trigger an acoustic and light alarm. The light alarm is a blink red light (Red Alarm Indicator Light), while the acoustic alarm is an intermittent sound.
You can stop the acoustic alarm by pressing the Acoustic Signal Stop Switch once.

When switching on the freezer for the first time, the Red Alarm Indicator Light will blink until the internal temperature has reached a level required for the safe conservation of frozen food.

Fast Freeze function
If more than 3-4 kg of food is to be frozen:
1. Press the Fast Freeze Switch for 2-3 seconds to activate the fast-freeze function 6-24 hours before placing the fresh food in the freezer, the Yellow Fast Freeze Indicator Light will illuminate. The compressor will now run continuously, to ensure that the fresh food is frozen as quickly as possible.
2. It is possible to deactivate the function at any time by pressing the Fast Freeze Switch for 2-3 seconds.
3. Place the foods in the freezing compartments (indicated with graphics).
4. Once the food is completely frozen (it may take up to 24 hours) you can manually switch off the fastfreeze function by pressing the Fast Freeze Switch for 2- 3 seconds and the Yellow Fast Freeze Indicator light will also go out.
5. Move frozen food from the freezing compartments into the other compartments (storing compartments) to make room for another freezing.

If the Fast Freeze Switch is accidentally left on, the fast-freeze function will be automatically switched off 48 hours later. The Yellow Fast Freeze Indicator light will also go out.

I believe that you all understand. If you intend to freeze larger amount of food then certainly a few hours before some shopping switch on the fast freeze function.

My volume on my sony tv wont go past 12 it will higher and lower but the maximum it will higher to is 12 have i maybe put a volume lock on it??


The only way the volume could be limited is if you were in the hidden tech menu----many of these sets have a setting there for initial volume level and maximum volume level.

Were you in the TECH menu for some reason?

I can tell you how to get in but you have to be very careful if you make any ADJUSTMENTS there--over 200 things can be adjusted there.

Let me know if I can help.

On my Sony Surround Sound tuner, if I raise the volume up to a certain level (not that loud), I get a flashing sign ''protect'' and the sound to the speakers are cut.


Sony has protection in these receivers for two main reasons.

1 - Checking for DC voltages on the outputs to speakers. Not your particular problem.

2 - Excessive current being drawn from receiver on one or more of the speakers.

Number 2 should be your starting point in finding a solution. Put the volume level on Medium - 35 to 40 on the front panel. Now listen to all you speakers in turn. Any scratching noise will indicate a defective speaker. Remove this speaker from the receiver output and check again if the set goes into protection on high volume.

If you could not find any strange noises on the speakers, remove them one by one and test the set on high volume.

Never - attempt to disengage the protection on this amplifier. The only times we have found the amplifier to be defective with this protection error, it has done so no matter the volume level. Therefore I believe your problem to be a speaker or speakers.

Good luck!
