DLP fan and power failure

Jul 7, 2005 11:54PM PDT

What recourse do I have if a power failure occurs while a rear projection DLP HDTV is on and the fan as a result can not cool down the lamp? According to the owner's manual damage can result from not cooling down properly. (Panasonic PT50DL54)

I would suggest getting a battery backup, just like the one used for a computer. Make sure it has enough wattage for the DLP TV that you have. Then, when you have a power failure, your TV will remain on. Turn the TV off the usual way, and the fan will run for a few minutes and cool down the projection lamp.

"owner's manual" While there is truth in this statment, if the lamp were damaged you would just have to replace it. Down side is there not cheep but $300~400.
So geting a good battery backup is not a bad idea. John

DLP fan and Power
Aug 13, 2005 11:04PM PDT

I have a Toshiba DLP 46HM94 on order and it appears as if it is a good idea to get a battery backup for it to protect the bulb against power outages and brief power drops(which my neighborhood has). I have a basic battery backup for my home PC that I bought at Sam's club that works great for my computer. Are the $300-400 units that you can buy at retailers for DLP TVs really needed?

I have a Samsung DLP and never thought of getting a battery backup. Whats the difference between using that and a surge protector. Does one suggest using something to protect my television from power outages? My apartment sometimes has that problem.

A surge protector dose just that, protects aganist surges or high voltage spikes on the power line.
Battery backup has a battery and power inverter that will supply 120 volt AC if you have a complete low of power in you apartment. How long it will do this depends on the size of the battery. But the idea is to have a peroid of time to turn of the set and let the fan cool the lamp.
For a DLP 500VA is the smallest I would get.
This is a good ideal for PCs also. John
