It may have a thermally sensitive component; set a portable fan aimed at the back of the set and see if that makes any difference.
If it does, it will require a technician to ferret out which part is at fault. Random problems like yours are real losers when it comes to repairing them. Many young techs will simply tell you that the main board needs replacement and that may be true.

I have a Sony Wega DLP with no sound through HDMI all of a sudden. Can't give exact model at the moment but it is a projection TV definitely 5years old at least. It has only 1 HDMI input and I've been...


The first step, and you hinted at it already, is to check cables and connectors. Especially with any electronics that old, connectors go bad if the wiring is moved, wiggled over time.

What you could try, since your WEGA is an older unit, is to connect your peripheral devices through the Component Inputs to your TV- at least one unit and see if the problem is resolved. Then you know for sure its either a cable or a connector.

Next step- try another HDMI cable and see if the sound comes back. If not, then its either the connector or the internal TV amplifier.

To troubleshoot the question on the amplifier, take a "Line Out" off your TV and run it to a stereo to see if audio is coming through. This is a lower level signal and doesn't rely on the higher power transistors required for a TV amplifier. If the Line Out audio works, then you know the TV amp needs repair.

Keep us posted!

I have a Vizio VF550XVT1A. First problem was a flickering screen that ended with the TV turning off. I replaced both invertor boards and the TV seemed to work fine for a few weeks. Now the TV works fine...


Good day sir Alfred!!!!

If your screen turns to back after a minutes but the sounds is normal..That problem is very common to all flat panel specially to LCD TV..

OK,I need to know first if your TV having a back-light when the picture went out after a minutes.If that so the possible problem is T-CON board (this board is the responsible to produce a video on all LCD TV)..

If you don't have back-light the problem is inverter board again..But before you order or install new inverter board try to find why the inverter board gone only on few weeks after you install it..the possible problem why the inverter board faulty for the short period of time is higher/lower input voltages (24vdc) comes from power supply..try to check it using volt meter or multimeter tester..it should be read 24vdc on meter..let me know if the voltage drop or higher to 24..

If the 24vdc is fine the only problem is the condition of inverter board maybe its used or partially faulty when you buy it..

if you have more queries and clarification regarding my solution please feel free to reply on this tread...

Hope it helps..

Thanks for using fixya..

Need 3 digit code for vizio vsb200 audio bar for a clikr-5 UR5U-8780L-TWM remote


There is no listed 3 digit code. You will have to do a code search. Press and hold the Ok and Aux button for 3 seconds. You will have to press the CH+ or CH- (does not matter which) for upwards of 400 times but the code is in there somewhere between 290 and higher, I lost count. Here are two tips. Move the cable box out of site of the remote and expect the TV to turn off when it hits its code. This will make you think you have found the code as the sound will go off. Don't fall for it. Look at the light on the sound bar only. Once the TV turns off you will need to have it;s remote handy to turn it back on so you will hear the sound again.

Once you pass 290 or so go slow and don't miss the light going out on the sound bar or you will have to do it all over again.

Once you turn the sound bar off press the AUX button again to lock in the code.

It's a pain but the code for Vizio sound bars is in there, don't let them tell you it's not. Took me about 7 tries to find the sequence and make the mistakes but my Vizio bar is now Programmed to the Cliker-5 and works fine. Good Luck.

The tv i bought at a garage sale it was working when i got it. I took it home and pluged it in and now it wont come on, it sounds like it is on and the little green standby light is on but shows nothing...


un-plug the TV, wait at least 30 seconds, now turn it on again and close your ear to the back of the TV while turning it on, pay attention on hearing a hogh pitching sound coming from the back of the TV, the sound may be quick and go from a lower frequency to a higher frequency really quick if this sound is present then it means the switching power supply. if you don't hear any noises then the power supply is bad. It could also be a bad horizontal driver transistor, it depends on the model TV you got.

Hi.

If the picture & sound are ok in analogue mode then chances are you have problem with digital tuner.
This may be expensive to repair so I would advise connect external freeview box or sky etc to get digi channels using scart to connect to your TV.

TV PROBLEM


I don't know your set in particular:

Genericaly, there are some models of sets that have a pre-set level for the sound. Check in to the menus of the set if there is a setting for the audio level at turn on.

Some manufactures designed their sets so that the sound is at about 30% up when the set is first turned on. This is annoying. They did that because they had people turn on the set and call their tech support that their set had no sound. It turned out that the volume setting was at "0"!
