Question about Nexus NX32031 LCD TV

2 Answers

My Nexus NX32031 won't power on. None of the caps are bulging. .

There are no additional lights inside. It does make a humming sound when plugged in. When I push the power button or the remote, the power light just stays red. It used to turn blue, flash power on the screen, then power off back to red. It doesn't even do that anymore. While it was starting to fail, I could get it to power up by unplugging before trying to power on. Now, nothing works.

Probably power supply failure, even with no evidence of bulging caps.

    I found the sticker on the board and it up comes up as a Hisense number, but it looks the same. Is it as easy as un screwing, unplugging and replacing?

Probably power supply out on the main board.
If you haven't before, buy a New TV and a UPS (battery backed up power strip) to protect your TV from power hits and Brown outs.

SOURCE: Nexus Tv will not power on.

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.4_12_2012_4_21_20_pm.jpg
Bad caps will look puffed up on top like these.

Very pronounced mid-rangy hum immediately after power-up with nothing connected to it. None of the controls (vol/tone) seem to affect it. Is this a common problem with an easy fix?

Probably bad Capacitors in you Power supply or Amp board.
Open up, check for popped or bulged caps.
If not, take it to a shop.
Careful, it might get worse...

Loud hum when powered on

its most likely bad capacitors inside the monitor. take it apart and look for 2 big black caps, there located right by the plug for the power supply on the PCB. they should say 25v 6800 uf.

if they are bulging out on the top and or have goo oozing out of them, there bad. these caps commonly go bad in these monitors because there rated WAY too low.

If you have to replace them, id go with some 50v 6800uf caps. they will be bigger and you'll have to solder leads and mount them elsewhere off the PCB, but you will NEVER have to change them again in your lifetime! (prevented no one else messes with it! )

Humming/buzzing from 221's Subwoofer.

You should replace the large Electrolytic(s) in the power supply. You should replace any other Electrolytic capacitor that the top is bulging or looks like there is something coming out of it.
Personally I would not recommend replacing any polarised capacitors with none polarised, unless you have seen an instruction from the Maker of the unit, which tells you to do so.
I recommend taking a look at the Bad Caps Forum for more information about Electrolytic Capacitors.

It most probably is the power supply board. There is a repair service which addresses any problem with the power supply board, not just bad capacitors:

I have sound but no picture

Always unplug the TV before you start....:)
On the Sanyo DP19648 has sound and NO picture.Take the TV apart locate the power supply board on left.Remove the plugs for the lights etc.take out the screws carefully unclip the power supply.Turn it over find the F1 tiny chip fuse locaed off center to the left with metal sheild away from you.I used a 2 amp (bc fuse unknown)I broke an agc style standard fuse and used the wire that was inside the fuse and also replaced the slightly bulged 220uf at 25volt cap which is located top side not far from burnt fuse.I suspect the fuse blew bc of the small orange bulged cap.
From Ed the tech....good luck

No picture no sound


It sounds like you have a power supply problem! You will probably find some bad caps (capacitors) on the board. They will look bulged on the top an may be a little leaky (brownish stain). In addition check the ribbon that feeds the lcd controller.

Need Nexus TV remote code

And just for what it's worth... I have a Nexus 32" (Model # NX32031). Although the 10463 code DID NOT work, THE 10178 CODE WORKED GREAT!
