Sony Grand Wega LCD Projection TV

[Nitwig]

Hi Guys, My girlfriend's parents are having a problem with their less than two year old TV. Sometimes when you turn it on cold the green power light will come on but the unit will have no picture. If you unplug the unit from power and plug it back in, it starts and operates normally. Is this a problem with the power supply? They purchased a service plan that is still going but they said they thought it was a bulb which they do not cover. I don't think its a bulb since the unit works after being unplugged and plugged back in. Do you it could be bad caps in the power supply or the inverter? In fact I dont even know what the inverter is, I just heard that they often fail. Any input is welcome. Thanks in advance.

That doesn't sound like the bulb. How long does that service plan go for?

It is a 3 year protection plan. I have a feeling that the guy will turn it on and it will work , so he won't repair it. It only has failed to turn on about 10 times total. The chances that it will do it for the technician are slim. Once the TV is on it has never shut itself off or had any strange behavior.

I would isolate the tv onto it's own plug in right away. Since too , that tech's can use a powerbar or otherwise to suggest that the problem may have been caused by other equipment attached to the same power supply source , at the plug.

This is true for PC's as well. If the problem persists at any time , change the plug-in itself in the wall. Then you can be sure that your tv connection is free from interference from other sources and it's connection is "current". You would be amazed at how many problems are caused by loose wires inside the plug-in box. In some cases , you can literally take the plug-in off of the wires because they were installed so that the plug can move. If the plug-in moves (especially when you have at least 2 large 3-pin plugs attached) being plugged in & out frequently) , the wires eventually loosen. Then you no longer have a consistant connection , you have a tempermental connection to the plug-in pins. This condition can be dangerous and even cause a fire when someone , unknowingly simply unplugs their tv (as according to the manual ) , on a plug-in that shorts to the metal box , via the loose wires.

If the box gets opened and there is nothing but (1 nail ) holding the box to a beam or worse inside the wall , chances are you have been experiencing an intermittent connection to the plug. The proper way for the plug-in to be installed , is in a box that is grounded and is securely fixed to the main wall upright beam with screws through the sides of the box. (Both sides) This requires small wooden spacers to fill any gap or an inner framework is the best idea to get the box secured before it is used to hold the plug-in in place.

Whenever I see that the plug-in is in a loose box , I shut the power down immediately. And I am left wondering why we accept plugging in an expensive tv into a $5 box that has not been secured? Also : run all your accessories (dvd/vcr/whatever) on a seperate power surge protected power bar at a different plug-in. It will at the very least keep any surges far enough away from the tv power cord where current can travel unnoticed. (Like lightning)

And this will enhance your warranty success if a serviceman calls to check the problem , finding that there is a fix inside the tv as well.

Since this is important and I have seen it so many times it makes me sick , I have to also suggest that you don't use the remaining plug-in on the same plug as your big screen is on (ever ). Things like vacuum cleaners are notorious for burning out while running , since they are crap.

I personally have a vacuum that is a "Rainbow". Allbeit they are expensive , mine is 15yrs. old now and has never even coughed. The "Rainbow" vacuum cleaner has what amounts to a pan underneath the spinning motor (downforce air) by design , refuses to allow any dust or lint or anything to enter the motor or escape the water that is simply poured into the pan before start-up.

When you see what is on your floors on a regular basis it will almost make you puke. The water turns black or dark brown , almost every time , no matter how clean your house is. Your carpets are like flypaper , they catch and pick up lots of small , loose junk. Then you simply empty the dirty water down the toilet and squeeze out the hair and lint and dust (sand) or whatever . Rinse the pan , fill it with water , and you are good to go again. There are no bags to pay for , nor does the motor wear because it has nothing going through it ( sending sand grindings back into the air ). This contributes to breathing problems , but is not present at all with the Rainbow.

In fact , there is now another vacuum that does the same thing (H2o) I believe it's called ($200) , is a small price to pay for what you get.

You might want to be sick when you see what the pan holds (every time) when used and mix in your favourite scent into the water and it will scent the air in the room at the same time as you are vacuuming.

These vacuums will keep the gunk out of your tv and other components as well (all the time).
