Hisense LTDN42V77US (2 months old) stuck in standby mode

I turned off the tv using the remote this morning. After work, I turned it back on using the remote, walked away and 5-10 minutes later I noticed it never turned on. The red light (indicating standby mode) is on. Read other comments on here with Hisense tvs getting stuck in standby mode (different models) but still tried those solutions...holding down the menu button while unplugging/plugging, menu+"9", nothing...I can hear the tv powering on/shutting down when I am unplugging/plugging, but it will not come out of standby mode. Any ideas? Button combinations?

SOURCE: tv stuck in standby

I believe these Sony TV's have a built in obsolesence and Sony does not care about fixing them. I don't think a 7-year old TV is an "old model". Who can afford to by an expensive TV every 7 years. Shame on Sony.

SOURCE: Panasonic Viera TH-42PV7HS Plasma keeps shutting down

hi there, have the same kind of problem twice so far after was bought for me as x-mas present (although my viera isnt plasma, its an LCD TX-32LMD70A)..

I Pulled out the mains plug for about 10-20 seconds and then plugged back in (power button at top was pushed in, in the on position, so when the power was on, the tv just goes straight on). It then worked.

i would however like to know why this happens ( i really hope this isnt a hardware problem, as like many others... its only months old!!)

hope this helps

SOURCE: green power light will not stop flashing and tv will not turn on or off

You need to replace the 1000uf capacitors on the DM board thats the classic symptom of the DM caps being bad the light continues to blink repeatedly. If you need more info on the repair let me know.

I have a ltdn42v77us tv when I plug in the wiring harness to power supply board it lights momentarily and then shuts off.


Fault at its main digital board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. http://electronicshelponline.blogspot.com/ In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.

Hisense remote control ER-32940A not working. what can i do ?


I know its obvious but have you checked the batteries, not only for power level but also the contacts if they are dirty from other batteries leakage. Also some batteries have short positive caps that fail to reach their contact which has to be eased toward the battery.

OK now the bad stuff many of these remotes have flash memory program which is why they all tend to look similar because they have specific equipment data loaded, as required to keep costs down.
The downfall is they can lose it just as quick, in which case you need a new one...
Another more rare possible problem is the TV is "blind" this used to happen when lots of remotes fired to their equipment causing an overload of data. Normal cure is to fully turn off the TV wait a short spell then turn on, if this fails then I would think back to your remote.

Now it gets trickier many items with push knobs work by the use of a rubber mat and contact pads, these I have found sweat and make a sticky mess between these pads and circuit board shorting things out thus stopping it from working.
Answer is to open them up (screws and clips some easy some hard to do) if you can and able to clean with this area with pure alcohol or meths and hope.

This is about it other than picking up one of those cheap £2-3 type remotes and hope they have a code to suit your TV at least then you will know that is a remote issue.

Hope this helps........

Call the HiSense tech dept. You can find the number on line and they will tell you how to fix it or you can try using the remote and go to settings and see if you can fix it that way. Also the manual for this tv should be available online as well.

The TV worked fine on Sunday evening, turned it off the normal way when went to bed. Came down to turn on in the morning and only the red light comes on indicating standby mode. I have unplugged...


Hello,

There seem to be a problem that is why the television is not coming up and stays stuck on standby mode.

First try to turn on the television using the remote of the television and ensure that the battery of the remote is properly working, you can as well try to push the channel button on the television if the remote does not work.

If it does not come up both by using the remote and pushing the channel button, then it means it is a hardware problem, and that is from inside the unit of the television. Since the standby light comes up, it simply means power is reaching the main panel of the television.

This mainly used to be caused by a faulty or bad capacitor on either the main panel or the power panel of the television.

To check and fix, follow the steps below:

Tv stuck in standby


Your problem is in the switch mode power supply or the horizontal out circut.
sometimes the small CHOKE that feeds the base of the horz. out transistor has a cold solder joint.
resolder both ends first.
