Over tv its getting aoutmatically off


Hello

Put your hand on the back of your TV to check for overheating, if your set keeps switching itself off without warning.

Many TV sets come equipped with a safety feature that switches the power off if the set gets too warm.

Check the cooling vents located at the rear of your unit. Vents can collect dust and dirt, resulting in the fans becoming blocked and failing to work properly.

Remove dirt from the vents with a damp, clean cloth. Ensure the air conditioning is kept at adequate levels in the room where your TV is located. Keep the drapes shut on hot, sunny days to keep the room cooler.

Check the sleep-timer function on your TV if it keeps turning off. A sleep-timer is used to turn a television set off after a certain period of time has elapsed. If the sleep-timer is not turned off, your television will continue to turn itself off after a certain period of time.

If the problem persists,then a heat sink has gone bad.

The on/off button simply toggles a low voltage circuit that powers your tv. If it is dusty, it may complete the electrical circuit and send a false signal.

Take a can of compressed air, open the back and clean the dust off the circuit boards.

NOTE;opening the TV VOIDS warranty!!

Dropped in toilet


Congratulations!!! remove every parts you can i.e. battery, SIM card and memory card. Make sure each and every single drop of water is out. Wrap the mobile phone thick with a piece of cloth and keep it on a warm place ( Not too warm ) like Above the TV( thats the best i can suggest) for couple of days, 3-4 days will be sufficient. Make sure you don't switch it ON while its wet otherwise the Flash IC might get fried by the battery. After 3-4days of evaporating the water from your Mobile, keep fingers crossed and switch ON the Mobile. If switched ON perfectly for 10-15 minutes (try checking all the feature in this time period) the mobile phone is in good status and if it doesn't kindly purchase a new Phone because i won't suggest you to get it repaired as once Nokia phone goes for a repairing it will always ask for repairing after 2-3 months.

RCA modelD52W20 Problems turning TV on when it is cold or for the first time after being off for an extended amount of time. The green lite comes on ,stays on a few seconds and goes out. After continueing...


well usually what works for me is a small heater on near the tv or just keeping the room above 65 degrees. There is a way on some tv's to turn off the power saver and that will keep your tv warm. But on others you cant turn it off so you have to deal with the heater or keeping the room warm cause that tv wont turn on for anything exept if its warm....

Tv turns on and off by itself


Picture tubes rarely go bad. You have a bad connection or something on the circuit board that is breaking down due to the temperature change . Probably an easy fix. Not something an unqualified person can do though. Your local shop should fix this for about $60-100.

Continually running/heating


Coffeemakers have two heating elements: a brew element and a keep-warm element. When the water reservoir has run empty, a thermostat switches power from the brew element to the keep-warm element.

The keep-warm element will cause the thermostat to stay in this condition until more water is added [or power is cut off] which will cool it down to switch back.

However, if the keep-warm element has quit working, the thermostat may be reactivating the brew element. With no water in the reservoir, the brew element will heat up till the thermostat trips again, then cool down, etc. This cycle will repeat until power is switched off.
