Question about Samsung TXN2745FP 27" TV

1 Answer

Samsung TXN2771HFX 27" TV

The TV has a strange powering off issue. It seems the longer the TV is unplugged, then when you plug it back it, the TV will work. I can only get about 4hours of use before the tv turns it self off. And to get 4 hours I have to have it unplugged for a couple of days. If it is plugged in and I attempt to use it every day then it will last 5mins to an hour before shutting off. Is there an easy fix to this problem? I have tried using fans to blow on the back of the tv, thinking it may be an over heating issue, but this has not effect. What are my options besides drop kicking it into the nearest land fill?

Too bad I didn't see this post earlier...it's probably OBE by now. Still, your problem is most likely a bad capacitor in the power supply. If you know your way around a circuit board, you can probably find the bad cap via visual inspection (bulging top, leaking electrolyte, etc.), and can replace it yourself.
NOTE: TVs have numerous high-voltage circuits, and large capacitors can retain dangerous charges for a long time after the electrical source is disconnected. DO NOT work on your TV unless you have the knowledge and skills to do so safely!! Otherwise, take it to a TV repair shop--this is a trivial repair for them, and it probably won't be too expensive.

My standby/timer light is flashing and will not turn on.


Hi,
The Standby/Power light of the TV blinks when there is any internal malfunction in the TV.
The self-diagnostic function of the projection TV will cause the STANDBY light to blink or flash when the television detects an issue. The number of times the STANDBY light flashes corresponds to a specific issue. As per the two examples below, some of the issues may be resolved without the need for service.
If the STANDBY light flashes three times in sequence, the lamp cover is not securely attached. Reattach the lamp cover to resolve this issue.
If the STANDBY light flashes four times in sequence, the TV may be overheating. To resolve this issue, ensure that the back of the TV is well ventilated.
If the flash sequence is not listed above or the light continues to flash, follow the steps below to perform a power reset:
Try the following steps to check if the issue can be resolved.
Turn off the television.
Unplug the television power cord from the electrical outlet.
Let the television remain without power for 60 seconds.
Plug the power cord back into the electrical outlet.
If the television is plugged into a power strip or surge protector, remove it from the power strip or surge protector and plug it directly into the wall outlet. If the issue is resolved, the problem is with the power strip or surge protector and not the television.
If the issue continues to occur, service may be required.

Thanks for using Fixya.

if you want to eliminate magnetism, you have to degauss the screen, if you don't know how to do that, here is a small guide for that: http://www.wikihow.com/Degauss-a-Computer-Monitor

but that strange shutting down its the transistor... so your best choice is to send it to a repairman to change the transistor..
if you try to do that for your self, you could even get shocked with the electricity contained in the tv... even if its turned off and unplugged..

It will not go on


try unplugging the power cord for 10-20 seconds then plug it back in. This is a when all else fails try. If it doesn't work it sounds like the T.V is going out. Check your T.V's handbook it might tell what the issue is.

Problem for Samsung TXN2798HF 27" TV Shuts off by itself after about 15 minutes. Sometimes longer sometimes shorter. Don't know much about the inner working of a television but I am pretty handy at fixing...


the power supply board is failing and needs replacing.replacing board is the easiest thing to do, lay tv down on a soft blanket(screen down), remove back cover and you will see the board. 4 screws and a couple of connectors and it is done. call 1-800-samsung to find the closest service/parts center to order board.
