Question about Samsung LN52B750 52 in. LCD TV

Adequate heat dissipation

On a 52'' tv, spacewise, there would be 1'' open above the tv and 2'' on each side. Is this enough space to dissipate the heat from the tv?

Car Amplifier Installation

Mounting your Amplifier The mounting position of your amplifier will have a great effect on its ability to dissipate the heat generated during normal operation. It has an ample heat sink for heat dissipation, and also designed with a thermal shut-down protection circuit ( most amplifiers) making it reasonably tolerant of mounting variations. Any configuration with allows moving air to be directed over the cooling fins will improve heat dissipation dramatically, DO NOT enclose the amplifier in a small box or cover it so that air cannot flow around the heat sink fins. Temperature in car trunks have been measured as high as 175 F ( 80 C) in the summer time, since the thermal shut down point for most amplifiers is 185 F (85 C), it's easy to see that it must be mounted for maximum cooling capability. To achieve maximum advantage of convection air flow in an enclosed trunk, mount the amplifier in a vertical position, on a vertical surface. Cooling requirements are considerably relaxed when mounting inside the passenger compartment since the driver will not often allow temperatures to reach a critical point. Floor mounting under the seat is usually satisfactory as long as there is at least 1 inch (2 cm) above the amplifier's fins for ventilation.
  1. Select a suitable location that is convenient for mounting, is accessible for wiring, and has ample room for circulation and cooling.
  2. Use the amplifier as a template to mark the mounting holes, remove the amplifier and drill as much holes as required , USE EXTREME CAUTION, INSPECT UNDERNEATH THE SURFACE BEFORE DRILLING.
  3. Secure the amplifier using the proper screws.

Please rate the tip if it helped you in anyway, thanks.

Furnace starts and ignites and fan comes on but when thermostat is turned off the gas shuts off and flame off but furnace continues to run. whu?? any suggestions?

The fan normally runs for a few minutes or so after the gas shuts off.

This removes the heat from the furnace and transfers it into the living space instead of just letting it possibly cause overheating of the furnace until it dissipates. If it is a fan that blows outside, that fan also needs to run for a few minutes to clear exhaust gasses from the furnace - to keep them from dissipating into your home.

What is my clearance regulations for

Hello Donna;

My name is Peter. I am a retired field service refrigeration technician.

The critical clearance, especially with under the counter units is in the back. You need extra space between the back wall and the heat coming off the compressor. I like to see 3" minimum. The more the better. If you are not getting sufficient air flow in the back then, your cooling condenser coil fan will constantly run in a effort to dissipate the heat.
Most manufactures recommend 1-1/4" minimum on the sides.

Gateway bios password reset

You'll have to open your case to do it.
1) Shut computer down.
2) Unplug computer power cord - IMPORTANT!
3) Wait a minute or so for all power to be dissipated. (Capacitors hold charge for a while even after shutdown.) This is for your safety, and to keep anything from happening to your computer.
4) Open case. The side is usually held on by 2 or 3 screws. Usually Phillips, could be knurled finger type. Open side by sliding back an inch or so. Then pull side away from case.
5) Look for a small plastic piece, about 1/8" x 1/4" looking from top. It should be on 2 of a set of 3 pins on the motherboard. There should be a label on the motherboard saying "reset" or "PW Reset" or "Password" or "bios reset", depending on which version of motherboard you have.
6) Lift the plastic piece up, noting which 2 of the 3 pins it is on first.
7) Put it on the other end of the set of 3 pins, using the middle pin over. (You are changing from one outer pin to the other outer pin.)
8) Put the power cord back in the power supply. Push the start button. Just a second will be plenty long.
9) Remove the power cord, waiting again for all power to dissipate.
10) Put the plastic piece back on the original 2 pins. Put case back together. Put power cord back, and turn on. The bios password will be removed.

Is there an option to install a freestanding wine cooler under a counter?

Yes there is. You should allow sufficient space around the unit (2-4 inches on each side of the cooler) allowing the heat produces during the operation to properly dissipate.

My whirlpool ED5VHEXV001 frig is not cooling well; freezer is doing just fine. Found beaucoup dust clogging the heat dissipating coils under frig. Cleaned 1st row of heat dissipating coils. Frig is now...

You can purchase special cleaning brushes to do that - BUT since I purchased one, I used it when I first got it and then put it away somewhere and can't find it. So I had to figure something else out, and what seems to work the best is to turn on the vacuum and put on the floor in front of the unit and then use an air compressor blowing it out from the rear. While it does blow dust into the kitchen, it seems to work well as cleaning out the condenser coils.

I originally did this as a work around for what turned out to definitely be a faulty HDMI card in the reciever and it worked well, you need to go(on the PS3) Settings then scroll down to Display Settings...

It's in the manual of nearly every piece of audio electronics to ensure adequate ventilation.

"7. Do not block any ventilation openings. Install in accordance with the manufacturer's instructions."

"18. If you install the apparatus in a built-in installation, such as a bookcase or rack, ensure that there is adequate

ventilation. Leave 20 cm (8") of free space at the top and sides and 10 cm (4") at the rear. The rear edge of the shelf

or board above the apparatus shall be set 10 cm (4") away from the rear panel or wall, creating a flue-like gap for warm air to escape."

But who actually reads the manual?

No heat

Over heat is caused by poor circulation of coolant. This problem can be: 1- The thermostat is not opening ( bad) causing coolant stagnant. 2- Water pump is bad, not circulate coolant. 3- Radiator is clogging up. It is full but water can not going through small clogging up tubes inside to have heat dissipated through the fines.
Since you also have no heat then I think the bad coolant causing the heater core clogged up also, unless the heater valve has a problem not allowing cooling flowing through the bypass hose to the heater core. Correct all 3 things above then you should be OK. Good luck.
