TV goes off intermittently

My TV runs fine for about 1/2 hour and shuts off, I start it again and it works fine for awhile longer and shuts off again. If I start it again the durration that it stays on seems to get shorter and shorter.

I had the same problem with my 50" Samsung. I solved it by aiming an external fan (4" from Tru-Value for $4) at the rear of the set in the bulb area. The added air-flow keeps things cool and the set runs until I shut it off. Samsung's fan wasn't powerful enough in the beginning, and when it loses the slightest bit of performance, it overheats and shuts down.

Hope this helps.

Sounds like an intermittent shut down which is heat related. some part , maybe one stuck on a heatsink is warming up and running too much current triggering shutdown.
to find it you can tell what is shutting down with a voltmeter, or you can heat suspected parts with a blow dryer to speed the shutdown .. or freeze spray to see if it goes beyond your shutdown time.

I have a slim 1500 that goes into and stays into stand-by


Check to make sure there is no short in the speaker wires. It is more than likely intermittent part or bad solder joints are responsible for the shutdown.

JVC LT47 that picture goes black (sound fine) after being on for awhile. Can turn TV off, then back on & it's fine. But then happens again about ever hour or so.


Hello
Hello
It is due to some loose soldering points [dry soldering we say it technically], in the power supply section of the TV. Just check for it. Check the solderings of all components, that will heat up to an extent when the TV works on. Repeated heating and cooling may make solderings to the terminals of that components to get loose. Just resolder all the suspected solder terminals, by applying a little more solder, without making any solder bridge short in between adjecent solder terminals. This must solve the problem to your tV. OK.

Hourglass picture. Panasonic CT-35G30T The picture is hour glassing from the sides. Starts to flicker back to normal after 1 to 2 hours. Getting progressively worse. Takes longer time to reach normal...


This is caused by bad solder connections in what's called the pincushion correction circuit. Some of the transistors get quite hot, and over time the solder connections to the TV circuit board become intermittent. When you tap the set, it causes them to make contact again so the picture is normal, but then it goes funny again. Resoldering the connections would take care of this problem. I would suggest calling a professional in to make the repair, which would cost far less than a replacement TV.

Hope this has been helpful, and thanks for using Fixya!

Nothing inn the canister after using,suctione working,bottom roller working,no air leaks from hoses.Also when running awhile it shuts off by itself,have to wait awhile to use again


I'm not sure what vacuum you have, but that sounds like a blockage to me. Thermal shut off kicks in, shutting the motor down, to prevent damage from overheating. After waiting like 1 hour it probably comes back on. Make sure hose, filters, bag (if any) is clean. All "airways" of vacuums need to be clear of any blockages, since airflow is what makes vacuums work.

Need Help big screen turns on thens goes off


a tv has two components, firstly a power supply produces high voltage to trigger a line transformer, in turn a transformer produces smaller voltages. firstly check if the ht is constantly been produced from a supply, if this is there than go to a line transformer, and check voltages at the output.

Crash!!


Could be Heat, sounds like the system is shutting down to protect the processor. Let it sit shut down over night and see if it runs longer when it's cooled down. Is the fan running?

If you are a electronics engineer, then check the smps +b voltage that is around 140volts for 27"t.v if is low or high then check electrolytic capacitors in the smps circuit and change the same ratings for continuid saftey, if +b voltage is ok then check the backside of E.H.T a small electrolytic cap rated 10micro 50volts for feedback replace it .

Remote Problems


Put new batteries in and try again. Sometimes the IR sender may also not be working properly due to a loose connection.
I would also suggest to open the remote and clean the contacts using alcohol. Rub the contacts on the key pad and remote gently.
Hope this works.
