Sound goes to 100% by its self - Samsung Electronics Samsung 50" UN50EH5300 LED-LCD HDTV, Black UN50EH5300FXZA

2 questions.
1. Do any of the remote functions work, IE. channel selector, settings menu etc.?
2. How old is the TV?

Several possibilities come to mind;

The remote battery is low.

The remote sound function may be faulty( bad button switch) this is usually a matter of how much the sound switch is used.

The automatic volume control in the TV has failed. This sounds like the best possibility. Once set, the sound should maintain its level. If not, the the AVC is dead and you will probably have to get the TV assessed by a tech. If this is the problem, you might consider a new TV. Tech service is expensive and in many cases it costs so much to fix a relatively simple problem, that buying a new unit is easier and more economical.

The latch is stuck halfway! Take your finger and push the latch all the way to the right until the oven light goes out. Now hold it there and press the self clean button. Let it start up for a few seconds then hit the off/cancel button and let go of the latch. It should hear it made a winding like sound as it goes back to it starting position.

The Charge lamp comes on with the Alternator fails to keep battery charge going. (lots of way to fail, and ALT Is 100% good) it's a system. each part of it must be good, end to end.
so...
i put my voltmeter across battery, i start car, i see 13.3 to 15vdc, alt is good.
no? , i see now, 12.2v. ALt is dead, (i didnt say bad) and battery is sightly discharged, 12.6v is charged. (key off, rested voltage)
This 12v tells me the ALT is shut down. only why is the question.

how can any charge system fail,
bad battery tops the list here, they LOVE to fail.
1: belt slips.
2: belt missing
3: bad alt.
4: bad wires to ALT . (corrosion on any wire or lug)
5: fuses blown , any listed below.:
your alt is not an ECU controlled, alt ,its 100% self contained

did you ever remove the ALT and blow the 100 amp fuseable link
the first step of any alt pul, is the pull the NEG, battery lug or BOOM.

im logged in to alldata.com so can you.

and what do i see.
a 5 wire ALT. one is the frame ground, so it must not be rusty or..... it fails. frame to engine block. no rust here.

wire L , yellow.goes to dash LEDs (alt failure idiot lamps) (this works)
wire. S white goes to ALT 5a fuse, is it blown?
wire :B B/G color, goes to the 100 amp link fuse. (blown>?)
wire IG Red-white, goes to a fuse marked 10A gauge.

i think the IG wire is the voltage sense wire.
no sense, no charge. I think the whole I/P dash cluster goes dead when this fuse blows.

The S wire is the boot strap voltage sense, it wakes up the regulator .
if open , the reg stays asleep, as does ALT.
Alternators can not self start, the regulator has boot strap device
that cures that. called self excitation. so this wire is critical.
All wires except the L wire is critical. in this case.

the B wire is the big wire, it charges the battery . 50amps or more..

any of the 5 paths open , kills the ALT dead.
The REG inside the ALT can also shut it down.
eg: battery bad, with huge cell resistances. total.
eg: overvoltge for any reasons. including attempts top run car with no battery, (dont ask)
eg: over current (battery cells 1 to 6 shorted) or 25 KC lamps added.
eg: over temperature shut down.

that is about it.

There is the problem with the toner, so please replace it.

Thanks

loose contact or the wiring gets wet.. try to clean those wires, if there is water thats the problem.. just like my wave 125

If the ABS light goes out, and stays off you do not have an ABS issue-it is doing a self-check for that second. As for the noisy tire, you could try moving it to a different location to see if the sound moves-if so, you need a tire, if not, check your wheel bearings at that wheel.

Try Ebay? Can you see any bad fillter capacitors (tops will be bulging out)

Try resetting the timer to manual, consult your user instruction book.

Rear projection hdtv, most likely damaged tubes. Don't repair this by your self get a tv repair man to do it before you injure your self.

1 it might be due to spraker wire loose or its connector loose. 2 loose contact in sound section. 3 some cap faulty. 4 sound ic might be grtting more supply so ic is getting over heated. 5 sound ic might be defective.
