Model #H25D34Y The volume on my TV goes in and out. How do I stop this from happening.

you use auxilry port in your tv as volume problem volume out from direct TV cable bos insert in tv auxilry port

What you're describing sounds to me like "Windex syndrome". People sometimes clean the front of their TV by spraying it with glass cleaner like it's a window (which it basically is) and wiping it off. Unfortunately the cleaner can run down onto the circuit board where it damages the switches and wiring. This might be what's happening in your TV, although the same trouble can be caused by other things as well.

The way the front panel controls are wired, a bad switch can cause all of them to act up. The remote sensor is part of the chain too, and if it goes bad odd things can happen. If the set is in an area of high humidity the same trouble can develop because of moisture. One of the switches might not be operating correctly, or another part in the button chain may have gone bad. The microcomputer in the TV may be bad. If you've had a recent severe thunderstorm with nearby lightning, this may have affected the chip.

Try unplugging the TV from the AC outlet, not just turning it off. Let it sit for 5 minutes to make sure that capacitors have had a chance to discharge. Press a couple of the front panel buttons before plugging the set back in. Then plug the TV back in and see if you still have the same trouble. This process makes sure the microcomputer inside is fully reset and often gets the set going again.

If the trouble continues, someone will need to check the front panel switches and the circuit board. That's the area where the cause will be found.

Most of the time it is the touch button assembly on the tv. The Volume down touch button switch is sticking.
I hope this helps,

Hi,

There are 2 reasons that this is happening in respect to the problem commencing after your daughter has cleaned the tv. Either your daughter has sprayed the volume button with cleaner and fluid has got into the the graphite pad under the button and conducting as though the button is being pressed continuously..or she has put too much pressure on the button if it is a metallic plate contact switch.One way to find out is by pressing the down volume button.does it it click ? if it does.try the up volume..If that doesnt click the problem is the metallic plate is dented in making contact hence a new switch. Another cause ive seen is cleaning the remote control with cleaner and fluid has got into the remote and it sends signals to the tv all the time..If the remote control is hidden under a cushion and the problem stops, then the remote control is at fault and needs drying out..Hope this helps :)

The circuit or integrated circuit being controlled has likely failed. You might try 'resetting' it by pulling the AC plug overnight. If that has no effect, a repair is unavoidable. This model seems to be developing a number of different problems.

this is the same type of problem happening with other rca models and I know it is the EPROM CHIP but why this is failing is either because of design flaw , dirty enviroment that they were made in , to much voltage or current to the chip or too much of a draw from the chip causing it to fail . Or even a random frequency from the IR sensor or its circut I'm still investigating and testing.
leave the tv unplugged for at least 3 weeks durring this time resolder any solder that don't look good , I did this and it lasted for about 6 months(always plugged in to the wall) before it started doing it again. model # 27v412t

Hi there!
I think your remote may be at fault. Liquid spill or sweat from the hand accumelates on the inside over some time and then becomes sticky. Some of the buttons may be permanently activated. Then other functions won't work. Have someone check it for you or if familiar yourself. Regards, JUS004
