Samsung TXE2546 25" TV Problem

When the set is turned on initially, it may run from 30 to 60 seconds. Then it will shut down, at least the high voltage will shut down. Then it will come back up for a few moments and sutdown for a few moments. This cycle will continue as long as the set is plugged in. At this point the on-off button won't shut it down.

Samsung turns off and on

This will most likely be a hard problem to find. These sets usually run what is called a 'switched mode' power supply. The power supply is starting, detecting a fault, (ie a heavy current drain), and then turning itself off to protect itself. Then it starts again, detects fault, shuts down, etc, etc. First place to look is around the horizontal output section as this is where the high voltage, high wear and tear, high temperature components are located and fail. I doubt that it will be as simple as a bad soldered joint but it costs nothing to look. Make sure the set has been turned off for 30 minutes or more before you touch. Capacitors take time to discharge. Please don't take offense, but, if you do not have experience in this field then I would consult a technician,

Tv is powering off and on randomly. Will stay on for 15-20 min initially, then will turn off and back on every 10-20 seconds.

There is a high possibility that the components over a period of heating and cooling, tend to bring on a problem of dry soldering. So my advice is to check the set for some loose joints that have played on to give you these erratic shut downs or poor performance.The best way to check for loose connections is to tap lightly when the set is powered on , If there is change while tapping then it seems that there are DRY solder joints. Remove main plug, the covers - with caution of high voltage, check for dry joints, use a good soldering iron to solder all suspected points.Sometimes the fault occurs when the set warms up, if so you can simulate the heat using a hair dryer on the suspected areas, try with the power supply, distribution, Processor controller, driver controllers on the A/V related sections. Also the use a FREEZE-IT spray can simulate the components to cool and show up the fault.

Samsung DLP TV HL-R5667W shuts off intermittently

Afraid there is no simple answer to this. This set has multiple things that could shut it down, one may be the balest needs a upgrade , this could be why it seems to be eating lamps. Another is what sounds like a fan is a color wheel , these have known problems of failing, and when this happens sometimes they shut down the set. And finaly does the set have good ventalation, overheating can cause huge problems with this set

How old is your TV?
TV's have a circuit that monitors the high voltage and shuts down the set if it senses something amiss. If the set is at least 10 years old this is typical and not worth repairing. If less, figure on replacing the flyback transformer.
Hope ya fix it!

TV's have a circuit in them that monitors the high-voltage and shuts the set down if it senses something amiss. On a projection type set, figure on just replacing the entire board that has the flyback transformer on it.

Samsung 56" shuts off after 5 or 10 seconds see a checker board image before shutoff

When the set shuts down you need to see what lights are blinking. For example: Timer/ Temp/ lamp on the front panel. You should also count the number of times they blink and the sequence. Most DLP`s give an error code alerting the technician to check the balast, lamp, or fan etc. for malfunctions. Unfortunately I can not tell you exactly what is wrong given the current information. Howrver, the last Samsung I repaired for shutting down had a bad light engine.
