What causes audio to suddenly increase to maximum?


Volume in modern systems are controlled by a single IC. If that goes, it makes the volume functions go wonky. The IC can be found by tracing the wires from the volume control, or following the circuit if it is mounted on a PC board.

Why does my Samsung LED TV have sound but no picture?


Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Viewing it in "Mosaic" or "Magazine" will make surf easy. Surf the site with patience. Pull up older posts.

HI, MY NAME IS S. A. ANSARI, I HAVE A SHARP AQUOS LC-32A66M LCD TV. ONE DAY SUDDENLY GOES INTO STAND BY MODE. NOW WHENEVER WE TRIED TO TURNED IT ON, IT ON FOR 30 SECOND I.E. WE CAN SEE PICTURE, HEAR SOUND...


Hi Ansari
It sounds like a main board problem. The control voltage that goes to back-light inverter board; from the main board, goes down. Contact any service technician. This is not a user repairable fault. Gopakumar Gopalan Google

My 52 ince screen stopped showing picture. It is just red, or yellow or green with thin vertical lines. I can hear that the channels are changing but no picture. Is there a reset button or something?


Hi,
To reset the tv to factory/ default settings, please follow below procedure.
Turn On the TV, while holding down Up Arrow on the remote control, press Power button on TV, tv will turn itself Off then back On again, release Up Arrow on remote control.
This procedure will reset all settings in tv to default settings.
Problem seems with lcd panel and I'm afraid it does not seems to get solved by resetting tv however try to reset tv by above said procedure.
Thanks.

Lc32gd8e backlight goes out in middle of a program


This is not a complete solution, but I have found that once the backlight has gone out, I can normally get it back by selecting the "Audio Only" option in the setup menu without turning the set off. This option is really intended for use with radio broadcasts when the picture carries no useful content.
When I press the 'menu' button on the remote and select the right hand most tab, the top option under this tab is 'Audio only'. I select the tab, and then exit from the menu until I need it. When the backlight goes out, I press the following key sequence:
menu, down, ok, right, ok, menu
and the picture reappears. Pressing the menu button opens the menu page at the correct (righthand most) tab. the down highlights the 'audio only' option, and the OK selects this. The right turns the option on (with the backlight working, the picture is removed, but the menu is still displayed). The second OK activates the option. The backlight is turned out. Finally, the second menu key press turns the backlight back on again. This technique has the advantage that the sound continues throughout the sequence, and the recovery of the picture is faster than waiting for the set to boot from a power off condition.
I suspect the problem is caused by an intermittent contact on one of the tubes, possibly as the result of some movement as the tube warms up and expands. (There are 8 tubes in the 32" set.) This causes a safety ciruit to shut down the inverter supplying power to the tubes. Switching off the backlight resets the safety circuit. If I manage to confirm this suspicion, I will write again.

TV input


it is likely that your tv is interpreting a random button on your remote as a signal sent for it to change inputs, next time this happens turn the tv off and back on and note what comes up on the screen, for example video 1,

No picture


Had the same problem ourselves.

Press set up on remote control.

Press the down button on remote control 5 times then press select.

Press the down button 2 times and press select.

Press select again.After 5 to 10 seconds the machine will switch itself off.

Turn off at the mains and then turn back on again and the dvd goes into preparing mode.

Go to AV channel and go through initial set up as you have just reset to factory conditions.Don't worry about any programmes on the hard drive they will still be there.Worked for us.

Audio problem


In your set's menu you should have an option to turn off/on the internal speakers,If you bring the menu up on the screen you should see options to change the video settings like color,brightness but also ther should be an option for audio witch include balance, treble,bass....in that screen you should see the option that says speakers try switching between on or off.Please let Us know how it goes or if you need more information.
