No sound, picture fine. Worked fine last time used. Tried Audio controls to ck for speakers either on or off. Can't get remote to change the state from on to off or reverse. Attached external speakers just in case TV speakers turned off. External don't work either. Any ideas out there?

Re: No Audio, picture fine
This is a very common problem just unplug tv for 5 minutes it
should fix it . simple fix most of the time with rca and proscan.
If that does not do it go into menu scroll down to audio and then press on .

It sounds that the audio output section circuit to your TV has the fault. The audio output IC, or speakers should be suspected. Contact any service technician. If you're sound in electronics, and wish to get more details,
check this link. http://electronicshelponline.blogspot.com/ Selecting the view option, either to Mosaic
/ Time slide, can be selected by the drop-down list, at the top left
of the display window, will make surf easy. You can also do a search, by type in the brand name/model
number/IC used, in the search box at the top right of the display window.
IF coming in via, the "Dish" networked receiver, please check that this volume is turned way up, on the TV. and then control the the Volume, with the Dish Remote, often this is a problem, as one is turned down, and the other cannot turn that up, simply try syncing the Volume controls, UP on TV, control the Audio with dish remote. thats all i can think of. Check by feeding a signal IN from an AV, source, ie: Yellow, Video, & Red& White, Audio. Turn TV UP and check, IF it responds to this all is well. If NOT then you do indeed have a fault, with the TV.
try accessing your tv settings menu and look for audio settings. usually there is an adjustment that you can make for external audio speakers such as when hooking up to a sound amplifier or internal audio that accesses your internal tv speakers.
I have a GE 46 in TV that had the same occurrence. I believe it is a sign that the amplifier is overheated or stressed. The way I fixed mine was to unplug TV and leave off for a few minutes -then plug in. I discovered this by accident when the power went off one day and the sound returned (had been using my vcr audio output plugged into my stereo for weeks!) This fix will work for weeks-sometimes months-evidently resets the circuits inside the amp somehow. Last time this happened I also removed the back of TV and blew out the dust with compressed air while it was unplugged-still have sound 4 months later without a "reset"-so I'm guessing it did help .
Last night i set childlock in my nikai ( NTV34010) tv set and tuned off by remote control.Then after some time later i tried to turn on tv but there is no sound and no picture.
will u please help me to solve it out.
What you may have is a cold solder joint in the audio section of the TV. To find this problem you will need a schematic, and mutlimeter, and a small audio signal finder. If you have a cold solder joint look in the audio section of the TV (The schematic will help you find it). use the audio signal finder to locat the position where the sound drops out, and then use the multimeter to find if the proper voltages are on the audio output components. This troubleshooting implies that you have the bacground in electronics, if you do not have a background in electronics I would suggest that you take the set to a qualified TV repair shop.
