First,unpluged the ac cord,then open the back cover,after that try to remove all the dust by using the a 2 inch paint brush.after that you need to visuallized the parts or the semi conductor if thres a cold solder,you need to use soldering iron to fix the cold solder or loose connection of the parts.look the wire of RGB or red green blue of the neck board.try to re-solding the connection between the mother board and neck board.make sure, no leads drop to avoid short circuit.

I have a barrier free sunroc high low cooler w good inlet pressure and low fountain pressure. Adjusted as high as possible. Can the water control cartridge be bad?


  1. Most water coolers have a "y" strainer installed in the water supply line within the cooler. This needs to be cleaned. Remove the cover, usually 4 - 6 screws, turn off the supply valve, and locate the strainer. It looks like a y. Before removing the screen for cleaning, bleed off pressure by pressing the water cooler button/bar. Now using pliers or an adjustable wrench, remove the screen by turning the nut located on the branch of the y and clean it.

Maytag DG410 gas dryer-no flame, no heat. I replaced the ignitor - that apparently isn't the problem. Other ideas?


Motor runs, but main burner will not ignite
1.heat switch set wrong---correct switch setting
2.defective timer or timer circuit---check timer wiring--replace timer motor or switch as needed
3.defective centrifugal switch in motor---clean switch or replace as needed
4.gas supply valve closed----open gas valve
5.inoperative solenoid coil---test coil for open circuit & the voltage to it
???
Pilot burner goes out
1.insufficient gas supply---- low gas pressure or clogged pilot filter or partially closed gas valve
2.carbon deposit on thermocouple tube---clean tube & check pilot burner for proper combustion
3.improperly adjusted pilot flame--adjust pilot flame until faint yellow tip begins to appear
4.faulty ignition or reset valve or thermocouple---replace

Clothes not drying, but dryer runs & heats
1.defective operating thermostat---test thermostat, replace if defective
2.fan or it's pulley loose on shaft---tighten set screw
3.incorrect heat or timer settings---reset timer
4.clothes to wet when placed in dryer----wring out or extract water from clothes before placing in dryer
5.clogged lint screen or duct (little air motion)---clean out lint screen & duct

I have an older Pioneer rear projection TV that has never been cleaned, model SD-P50A5-K. Can you give me the basic cleaning instructions and the do nots for this TV.


Unplug the TV for safety - even unplugged, there is enough energy stored in the electronics to be very dangerous.
The bottom speaker grill snaps straight off. There are a row of screws under the screen around the screen bezel that must be removed. The bottom of the screen will become loose and the whole screen assembly slides up, like opening a window (there is a bracket under the bezel at the top of the screen that the bezel slides off of.) My screen took a lot of effort to disengage the top bracket - careful not to break anything!!!

Once the screen is off, put it safely aside. There is a mirror in the back that can be cleaned with a damp cloth (not dripping wet!). Remove a little dust at a time and keep washing the cloth out between cleanings. Be very gentle. If you push on the mirror it could break If its never been cleaned there is sure to be a lot of crud.

Below the mirror are three colored lenses. CAREFULLY use a clean lightly damp cloth to wipe each one. Don't mess with any of the adjustment screws and levers on the lenses.

Before putting the screen back on the TV, carefully clean it with a damp cloth too. Slide the screen back over the top bracket, put the screws back in, and pop the speaker grill back on.

Its a good idea to readjust you convergence too.

When I cleaned my set, I was amazed at how bright and sharp the picture was!


Be Careful!

Yesterday I cleaned my inside glass of my cooker (moffat94971100) The sealant popped and I have a loose glass. I have found sealant however how do I get the door off and weigh down the glass is there any...


Hi.

Normally there is a clip on both door hinges to allow easy door removal.

Once door is removed place on a towel on a flat surface. You will find a couple of screws on the top of the door and possibly underneath. Unscrew these and the two halves of the door should come appart. The inner glass is held in place with high temperatute oven sealant. You will need to thoroughly scrape the old sealant from inside inner door and on glass.

Apply sealant bead to inner door (but not too close to the edge) and then gently lower the cleaned glass on to the sealant. Press down gently. Now the sealant must have 24hrs to completely set so place a towel over the glass and place some heavy objects on the towel. House bricks are good if you have any.

Once dry you can then screw both door panels together and refit oven door.

Is screen on 50'' HD sony rear projection removable for cleaning?


It would be a good idea and a wise investment to have this done by a professional who at the same time can perform any necessary tune up / adjustments to your set. This service will allow you to watch and figure out what you need to do in the future to remove the dust yourself.

Please Help with color & screen Cleaning


You are going to have to adjust the three screens in the front of the set behind the speaker cover. You will need to adjust the Red, Green, and the Blue all to look like a B & W picture so turn down the color or put in a B & W movie from a DVD or VCR. Then adjust each screen till you get the best blend and a good grey scale. Grey scale is the best B & W you can get on the TV set. The screen has two surfaces on it. The outside part goes up and down and is called the lenticular screen, and the inside part has round circular pattern too it and is called the freznel lens. The circular screen and the outside screen can be cleaned with a car polish cloth called a Shammey. Use deluted windex and only wipe the rag in the direction of the screen, eather up or down or circular. Good Luck
