Samsung LE32A457 32 in. LCD TV - Answered Questions & Fixed issues

You may lose some channels when you retune the TV as the channels have been rearranged. To locate them look at the EPG although you may still find that some channels are no longer available on FREEVIEW. See the following link for additional information

If the above process does not work then check the link above for additional information and also visit the accompanying site links below to find more information for your model of TV / FREEVIEW box.

I have a Samsung and it has worked with anything I've connected to it so far. Check the manufacturer of the sound bar you want to use.

Check whether the audio is muted by accidental press at remote control button. Enter its sound menu, and check it. If muted, as you know there will be no audio output. If not muted, check the speaker/s. If found OK; check and replace the damaged component/s at its audio output section circuit board. If needy, replace this board as card basis.

Very likely that one or more component capacitors have failed, unplug from electrical power, remove rear cover and inspect using a flashlight for leaking/bulging capacitors. This will require soldering experience to replace.

Must be to a fault to its T'Con board.

This sounds like a very common issue.If set is hard to turn on (takes several tries)but will eventually turn on hereis what my guess would be.Every set has a standby power supplythat is running 7/24 if the set is plugged in and it supplies voltage to theremote circuit that turn on the main power supply for the tv and hence turn theset on.This is an area where companies cut corners by using lower rated voltage caps.By this I mean Standby usually provides under 10 volts to trigger the seton----what they do is use filter caps rated at say 10 volts max in a circuitwith 9 volts (example)=with the standby on all the time the filter caps(electrolytic caps) dry out and fail.The problem usually begins where you have to turn set on or or two times andgradually gets worse--takes longer and more tries to get it to come up.Once on it will stay on until turned off for a period of time.The caps will begin to work better (regain some of thecapacitance) as they get hot--hence one it is on it will seem ok.The beauty of this problem is most of themhappen when set is a year or two old (no warranty) and all you have to do islook at the top to locate bad ones.They are generally black or blue and round and vary in --they have twoconnections each--a + for positive and a - for negative--not unlike a batterywhich in a way they are. The + and - are marked on top and bottom of most boards.They are easy to replace and not expensive parts.The tops are silverand metal looking with creases on top and if bad they will be puffed up ontop---tops must be perfectly flat with no brown material leaking top or bottom.If this is your problem once you id them (make a drawing) you can begin.Here is the critical part---on each cap is also marked the value like 220uf 10vdc---220 micro farad at 10 volts maximum.If you find for example 6 puffed up and all are 10 vdc replace them with thesame value capacitance (like the 220 uf) but go up to at least in this case(from 10 volts) to a 16 or higher rated voltage cap.The only issue is when you go up in voltage rated value the cap is larger sosometimes there is an issue of physical space for the replacement on the boardto fit them in.The reason they cheapen these sets in this way is if 10 caps and you make25,000 sets there is a considerable savings in parts cost. They do not care as long as it lasts past the usual one year parts warranty.I have taken the time to be long winded because this really sounds like it maybe the problem you have.See attached photo of a typical cap and if you have questions or need advicelet me know.

IT LOOKS LIKE WE ALL MAY ASWELL STEER CLEAR OF SAMSUNG AS THEY ARE **** BRANDS YOU NEVER HEAR OF THEIR BETTER BRANDS SONY GOING WRONG AS THEY WOULD BE IN IT UP TO THE NECKS WITH INSURANCE CLAIMS ASWITH PANASONIC , SAMSUNG ARE YOUR CHEAP WASHING MACHINE THAT ISNT WORTH A REPAIR ,IT ENDS IN RECYCLINGTHATS WHY THEIR ARE LOADS OF MODELS OF THEM, THEY ARE NOT WORTH 300-500 QUID YOU MAY AS WELL PAY MORE AND INSURE IT FOR A FIVE YEAR WASHING MACHINE GUARANTEE BECAUSE IF A LCD OR PLASMA DOESNT LAST FIVE YEARS ITS TIME GET OUT AND ABOUT MOREINSTEAD OF SITTING ON OUR ARSES, LIFE EXPECTANCY YOUR AVERAGE WASHING MACHINE ,FRIDGE,COOKER, HOOVER,CAR ETC IS 5YEARS SO WHY DOES THE MODERN TVS DONT LIVE AS LONG REASON PROFITS.GAZ SORRY FOR THE BOREDOM.

this is a problem with the switch mode power supply unit,check for the components not functioning in this unit and replace

Hello

First of all, it is not a USB port/slot, it is a 3.5 mm slot. And it can only be used Samsung technicians for "service" and nothing else.

Thanks for using Fixya!

Can buy fuses it at any Radio Shack stores.The fuse it at the end of the power supply board.That the board,where the power a/c cord plug into it.Modern electronic equipments have very small chances the fuses dies in the normal operating situation of the devices.Tv have the power supply board problems.Tries websites like Shopjimmy.com,Ebay.com to buy a whole refurbish power supply board for the replacement.

good day

yup,the easiest way to fix your problem is to replace new set of power supply assembly for your TV..
but I suggest as a technician to try to replace capacitor if it is leak/bulging top..its very easy you can do it...

watch this video to guide you for replacing bad capacitor
thank you and good luck..

You will need to take the back off the tv and check for puffed capacitors. If they are puffed, you will need to replace them. Replace with rated capacitors equal to or slightly higher values that are printed on the capacitors. Their values are mF and voltage. If this doesn't correct your problem, you will need to check the voltages on the power supply. If you have a constant standby voltage of 5VDC. but no other voltages, it is probably the main board.Send me make, model, serial number of tv so I can do further research. Thank you

We have a Samsung LE32A457, whilst we were watching T.V tonight the top halve of the screen suddenly appeared with green lines halfway down the screen and that half of the picture was unwatchable, T.V is 2 years old. We have removed all scart leads but this did not help and the problem still exists, when shutting down a white horizontal line across the centre of the screen appears from this line upwards the picture is faulty. Any help or advice would be grateful.

Hi,

This is an indication of out-of-regulation in the power supply section. The very common caused of this fault is the leaky electrolytic capacitor in that section. It will drop the supply from normal voltage and will disable the unit.It needs a little warm-up to make itself stable but the symptom will get worst. Sometimes it has a bulged/dome at the top but not all, it is better that you have a capacitor checker/tester to determine its condition. Your unit will back to normal again if the leaky capacitor is isolated. Yes fixing the power supply is quite technical but in this case a little backround in electronics will be fine because electrolytic capacitor is the only parts that are going to be replace. If you don

This tv have a commonly problems with many other LCD,Plasma screen tvs have,the tv power supply board problems as dying and soon to be dead parts call capacitors.That the board,where the power a/c cord plug into it.Take the tv aparts.Searches all coners of the power supply board,look for dying and soon to be dead parts call capacitors,these capacitors alway bulging or puffing up onto it tops.These dying capactors,must be replaced,will solved ur deplaying and shudown problems to the tv.U have all the tools and understand basic ectronic aslo can do basic soldering work?Or tries websites lke shopjimmy.com,Ebay.com to buy a whole refurbish power supply board for the replacement.

hdmi is auto detecting and shouldn't need to be turned on. try plugging your hdmi1 device into the hdmi2 slot. if switching devices around doesn't get hdmi2 working, that jack is likely broken. all the hdmi ports go into the 1 main board inside, and a lot of times you would have to replace that board to fix. if only 1 jack now works, you could also get an hdmi switcher, and then plug all your devices into that, and then just plug the switcher into the working jack. let me know if I you require further assistance.

my colour is green why?

hi,

it is the ip board (power board) capacitor had already exhusted. got to replace either the board or capacitor.
