My philips lcd have statrting problem in winter tv turn on some after statrting room heater
Some flat screen TV's generate a lot of heat at the back. You can do some test by placing the palm of your hand above the TV or even a thermometer on top the TV without touching the TV body and see how the TV temperature fluctuates during the 12 months of ambient temperature. In Summer, it my run hotter and in Winter it may still run hotter because of these reasons... the TV is close to the heater, it is inside a wall unit or it is in a corner where no air circulation is present. In the wall unit, no air circulation is present and the heat you feel above the TV is actually whatever bit of cool air it can draw from the rear part of the TV openings to cool the components. I know that most TVs are always close to a heater, fireplace, or a radiator that generates heat towards the TV. Again, if you put a thermometer on the TV and observe the different temperature range, you will notice a raise in temperature on the thermometer when you have the TV placed by a wall whose outer wall is facing the hot Summer sun, or when you have any means of heating system to keep your house warm in winter (while you live inside wearing a T-shirt and shorts), a warm fireplace (gas or wood) next to the TV, and or an electric radiator, or an integrated home heating system. These affect the appliances that rely on cool air circulation. And TV's are the first to suffer from excess heat and they seize unexpectedly. So, the first thing is to keep the home temperature under 25C by reducing the heating system and wearing proper winter clothes instead of T-shirts, etc. If the TV is next to a fireplace, that room is really warm and is suicidal for the TV. Move it where it is cooler and not in direct heat from the fire. Stand by the TV and see if you can feel the fire heat radiating in your face. If it does then that is no place for your TV. Move it away and rearrange the seatings so that you can watch the TV and still have the heat radiating to you, and not the TV. of all the modern technology we have today, the TV still doesn't come with a cooling fan like a computer and yet they generate more heat than a computer. If you have some wiring experience, go to an electronic store and buy yourself a large (4 inch) silent cooling fan, either mains operated or 12v. Mains is usually plugged directly in the mains socket, but 12v fans need a 12v, 1 amp transformer.
With some plastic covered wire ties, insert them in and out of the cooling grille at the back of the TV, usually the lower ones because that's where the cool air enters and exists at the top as hot air. Then attach the fan against the grille with one end of the tie inserted in the corner holes of the fan body and with both tie twist them tight and firm. You must make sure that the fan is placed where there is a large slotted area to freely allow as much air as possible, otherwise it either makes air noise or it will not cool effectively. Most TV rear cover has a generous amount of apertures in the form of vertical slots or hundreds of holes for cool air to enter, but a fan will force more cooler air, therefore the TV will run cooler. Then you connect the fan wires to the transformer. It's a pretty straight forward wiring if you're know a thing or two about wiring, plus - less (+) (-) voltages and cable colors. if not have it already wired and working by an expert to save you the stress of this wiring. But I believe the placing of the fan on the rear of the TV should be a piece of cake for you if you followed the simple advice above on attacking and tying fan on the lower rear part of the TV. Alternatively, if you've got money, let an qualified expert do the work foe you for a small fee. You just buy the fan and the transformer to suit. Don't forget to ask questions when you buy them, does the voltage on the transformer match that of the fan? Remember the fan will run all the times so, when you switch the TV on you want the fan on too. So, to make it easier for you, buy one of those remote controlled power boards on the market today. Plug a divider on one of the socket on the board and connect the TV cable plug in one side and the transformer on the other side. Since it is the TV that you watch most often, use socket one (number 1 on the remote). When pressing number one on the remote you have power for the TV and the fan. When you finish watching TV, press the same number one button to turn its power off or press the main button on the remote that removes all power to all devices, therefore it will save you electricity by disconnecting any power to any appliance connected to power board's sockets. Hope this explanation helps you one way, or another. Cheers.
