With projection TV's the lamp is usually the cause for cycling issues. The lamp power supply (ballast) monitors the current drawn by the lamp and adjusts voltage to keep the current at a specific value, if the ratings fall outside of spec the TV will cycle power and attempt to correct the anomolie. If this happens too many times within a specific time frame the TV can refuse to turn on and will indicate an error code. Don't put the TV through too many retrys or you could damage the ballast too.

Lamps can cost between $200 and $400. The ballast can cost anywhere from $150 to $250 approximately. Usually the manufacturer of the TV will sell you a new bulb, but electronics suppliers often sell them for less. Most lamps are owner replaceable and easy to do, consult your owners manual.

In-home servicers can base their labor charge on the size of the TV. The larger the TV, the higher the labor cost. Do it yourself and save!

Hope this helps.

Coolant fan continues to run while van is off......


most modern vehicles have fans that can run for 5-10 minutes after the ignition has been turned off if the engine is hot.
if the fan runs for more than 15-20 minutes there may be a problem with the temperature sensor for the fan.
this would normally be located on the side of the radiator and is fairly easy to change.

if you need more detailed instructions on changing this then please feel free to ask, but if the fan turns itself off within 10-15 minutes then there is probably nothing to worry about.

It seems that the temp more often goes up to 20-30's and that food is not as frozen when I check it. When temp goes up I check it for next couple of minutes and usually within 10 min the temp is back down...


This is normal. All commercfial freezers must defrost 3 to 5 times a day, or they will freeze over at the coil and then stop freezing. A timer in your freezer turns off the compressor and turns a heating element on for 10 to 15 minutes. During that time the coil heats and melts frost from the coil. Usually within 30 minutes the temperature will briefly rise to 20 t0 25 degrees F and then quickly drop down to 0 degrees F. The food rarely defrosts in this short period of time..

I have a samsung HT-Q100 and its plays well but it will turn off itself after 45 minutes of playing time. I've check the back of the player and it heats up really hot( on the right of the fan at the back)...


If the fan is not providing sufficient cooling (it could be that the fan needs replacement), try placing a portable fan where it blows on the back of the unit. If the unit continues to work, you'll know you need to replace the fan within the unit.

My LC-26sh12u takes 10 minutes to


I had a similar problem where it displays "PLEASE WAIT" for several seconds alternating with blocky colors for several seconds and continuing anywhere from 5 to 30 minutes.

I inferred from a couple of sources that the TV is booting up when it says "please wait" by reading data from flash memory. I was able to fix my problem by resetting the data in memory to factory default values using this procedure from the service manual (wait until the TV is working before trying this):

Turn on the POWER.
Set the VOLUME to minimum.
Press both VOL. DOWN button on the set and Channel button (1) on the remote control for more than 2 seconds.
After the finishing of the initializing of shipping, the unit will turn off automatically

Trans shifts very hard after 5 minutes of stop and go traffic


A reason for hard shifting could be a problem with many things with various degrees of seriousness. It could be your ATF( automatic transmission fluid) is low or broken down and old. This would cause the hardness and the reason for stop and go traffic effecting it. Another possibility is your transmission is just shot, and the timing gears inside are worn and not properly shifting at the correct RPM causing a **** during shifting.

Some possibilties, not all!
