SOURCE: Little white dots on the screen

Had an authorized warranty repair center out, they said the projection bulb needs to be replaced, "good thing it's under warranty." They should be back next week to replace, hope that fixes it.

SOURCE: Small white dots are showing up on the screen when

The white spots you are seeing are a result of dust or dirt in the light asm. Mits knows about this as a problem. The inside chamber of the tv needs to be cleaned. If your tv is in warranty they will come to your home and fix it. If not it is very easy to damage the tv by trying yourself, start with cleaning out the chamber that the bulb is in, use compressed air to blow out dust and dirt, them on the sides of the tv are round flaps that will need to be removed and this will go into the main mirror chamber, be careful but blow out any dust or dirt you see on the mirror. I would have a repair tech handel this unless you are skilled in this area.
good luck

Engine making whining noise


There are a couple of things to check. If your power steering pump is low on fluid, or a bad bearing is in the Alternator, they will whine. The PCV valve or any hole in the Vacuum lines will whine as RPM is increased. Even having the Air filter box not fully seated will make a whining noise.

Now both automatic and manual transmissions can whine as RPM is increased. Check fluid for each.

Serpetine belt and pulleys-can make noise.

Sometimes you can shift into neutral at any speed and the engine rpm will drop almost instantly as the car rolls at speed. If the problem disappears as soon as the rpm drops, then an engine part probably is the reason.

This tv is under five years old?Yes,it is worth fixing.Over five,i would compare the prices for a new LCD tv and the quote priced from the Tv Tech.for the old tv.This tv have high voltage problems around the Deflection circuitries area.Could be any things burn in this area.The high pitched whine sound,i'm sure it is from the FBT-the high voltages flyback transformer,high voltages current have no where to go.Must hire a tv tech. to troubleshoots and replace parts on the Deflection circuitries area.Also the FBT could be dead too,because HV Current bounces back forth and have no where else to go.The prices to troubleshoot unknown problems is about $400 bucks and plus cost of replacement of parts.

Front end noise when turning. almost sounds like


There are a couple of things to cause metallic sounds when turning. First thing, is if it's a clicking sound when you turn, then you have a cv joint going bad. It's usually more prominent when moving in reverse, however it can happen just as well while moving forewards. Secondly, if it's more of a grinding or scraping noise, we have a couple of options. The sound could be coming from the brakes, if they're worn or have grit stuck in them, or it could be bad bearings in the front wheel hub. The wheel hub has a tendency to making a whining noise when driving; usually most easily heard when driving past buildings. They can also allow the tire/wheel to present the appearance of leaning when looking at it. If bad enough, it can even rub on the brake caliper, or cause the disc brake rotor to wear out the brake pads prematurely. So, to recap: Check:
CV joints, if a clicking sound brakes or wheel hub bearings if grinding or whining sound.

Samsung DLP HL-R4266W..no sound or picture. TV is completely dead


Assuming the noise is a high-pitched whine, then yes, it is the color wheel.  If the color wheel goes out, the TV will turn on for a while, then turn off when it can't establish color wheel sync.  The color wheel has to be in sync with the mirrors on the DLP, so if sync can't be established, the TV turns off.
You can order a new color wheel from Sears or partstore.com (among other places) and replace it yourself, if you are so inclined.

Whining noise


The problem i had was when i would play my tv. I had it hooked from my dish to the sony then the tv. When i played a dvd,cd or the tuner it didn't make that noise. It seems my video/audio 2 channel was going bad. I disconnected my rca jacks and used the optical audio connection. The noise stopped and i got a better quality sound.

hope this helps
