Picture and Sound went off in the middle of a program. Now when I try to power up the set, it emits a low frequency, slow, pulsating whistle, which eventually stops when the set cycles and shuts down producing then three blinking LEDs.

Re: No Picture No Sound
First look for Bad Capacitors on [power supply board,if anyone of them is puffed up on top they are bad,Then if you do not have any bad caps How old is the Lamp in Set? if TV recycles 3 times for turn on and you have 2 greenlights on front and one red light---- lamp needs to be replaced.

Sounds like either there is a problem with a low frequency driver or perhaps an eq setting.
If you have an external (line) output, you can try sending the signl through another amp. If you have headphones, then try them also. If the headphones sound distorted as well,then see if you have the eq to high on the bass.
Other than that, it could be a filter capacitor in the power supply. You would need some experience fixing that.
Settings of bass, treble and equalizer is a matter of personal choice. You can set them to your liking. Alternatively you can choose the sound mode ( like music, movie and theater ) of your choice. The balance setting off course must be in the middle or zero position so that both the speakers give equal amount of sound. In equalizer the extreme left column represents the low frequency sounds like the sound of drums. As you move rightwards the sounds go on becoming finer and finer and the extreme left column represents the fine sounds of the instruments like violin and sitar. Somewhere in the middle is there is human voice also. Play some music, try varying each column and see the effect. Good luck.
H?, You have a very good system...one of the best of SONY..SUB does not get activated automatically especially on STEREO mode.DIRECT STEREO Notes • No sound will be output from the subwoofer. .your system has Dedicated Power Amplifier for 2 Externally Driven Sub-Woofers (200W RMS x 2)..in order to activate the sub woofer amplifier you need to make a selection on the surround modes while you are switching the modes of the surround you will see the speaker position on the display of receiver as well..if you do not see the sub woofer it wont be activated..Sound Field Program (A.F.D) is a good example to test it.. Take care and please Remember to rate/vote and give me 4 Thumbs Up for Helping out the Community :) Hope this helps! -------------------- Additionally please follow the instruction on your user manual to activate the SUB ,as is follows.. ----------------- BASS-OUT
Low-frequency (bass) signals can be directed to the
subwoofer and/or the front left and right speakers
according to the characteristics of your system. This
setting also determines the routing of the LFE (low-
frequency effect) signals found in Dolby Digital or DTS
Choices: SWFR (subwoofer), FRONT, BOTH
• Select SWFR if you connect a subwoofer. LFE and
low-frequency signals from other channels are directed
to the subwoofer according to the speaker settings.
• Select FRONT if you do not use a subwoofer. LFE and
low-frequency signals from other channels are directed
to the front speakers according to the speaker settings
(even if you have previously set the front speakers to
• Select BOTH if you connect a subwoofer and you want
to output low-frequency signals from front channels to
both the front speakers and subwoofer. LFE and low-
frequency signals from other channels are also directed
to the subwoofer according to the speaker settings. Use
this function to reinforce low-frequency signals using
the subwoofer when playing back sources such as CDs.
Try "reading" the radio before programming it. It sounds like the programming software is using the settings from one radio to write to another. It's highly probable that the firmware is different on the two radios.
It's always a good idea to "read" a radio befor trying to 'write' to it..
If the TV programs come's up with sound, then is possible that the TV set could be problem free. then cheek the system frequency if it need to be adjust from NTCS, PAL, AUTO MESECAM and so on. Cheek the DVD and VCR if they are in one of the following system settings and adjust the TV set to the settings at which the DVD or VCR is set to. Then you can also cheek if the cable is properly inserted, that is audio to audio and video to video. Nevertheless, if you have properlly connected your cables and set the system frequency to match with each other, and still no sound, then the TV could have sound problem.
Possible courses of sound failure in TV are as follows:-
1 RF stage
2 sound Ics or transistors
3 broken speakers
4 a break down resistor which supplie positive voltage to the sound curcult
if you have some knowledge about electronics u can open the back cover of your t.v and check if there are some parts that is being burned up, replaced it with the same part number. but be careful because t.v is dangerous because of its high voltage
If the light is flashing on the front of the set after you turn on the power, its most likly a sweep power supply problem. if the set is dead then its in the standby or main power supply. If your hubby is a tech then he should have No problem fixing this puppy. if he is not, a TV set is not a place to be experimenting around inside of, as this is a solid state set, and has no user replaceable parts inside. Its dangerous to work on and unless you wantt to possibly become a widow?? Please seek out a pro to assist you in this repair.
