    There is often a menu in the TV which allows you to turn the internal speakers on. You access by pressing the menu button on the remote, or through the menu button on the TV.

    Please reply what make and model of TV and we can possibly help you more.

Color looks white washed!!!

there are in the older rear projection sets lens for those that do not use a lamp for a light source.

In the older sets there are three large black lens that can be seen and reached with the rear cover off---if there clean them as they are the light source in those sets and if dusty picture will look dull and darker than it once did.

If in doubt shoot me a model number.

The question is not about the TV...which by the way is not the one listed. The one I have is over 10 yr old...I didn't see a listing for the one I have. My question is more general...what is the

A few answers: A home receiver can be a unit the signal and speakers and other units are all centrally connected to and the unit routes them to the set.

A strictly audio receiver processes sound and many of them have a amplifier either built in or external to boost audio to external speakers----Stereo units are one type and home receivers are another type.

1 have a 6 year-old Mitsubishi model WS-48511 series 1080 rear projection TV that now won't turn on. A few days ago we shut the TV off, and now when i plug it in the blinking green power light...

This is called the blinking green light of death-----only one of two things can cause this problem.

First: remove front speaker grill (IT PULLS OFF) AND remove inspection plate behind it; look for the two bundles of wires coming down and to the right from the front keyboard of the set.

Unplug both plugs you find (different and marked so you cannot mix them up-----the idea is to take the front keyboard out of circuit-----set will still function with remote as receiver is behind front screen)

Try (after 70 seconds) to turn on with remote

If it comes on---defective reset button on front keyboard----use set only with remote or remove and remove actual reset switch---it is located behind and part of frame for screen----entire front screen would have to be removed to get at it.

Second: if disconnection of the front keyboard does not help, the DM unit is bad.

As you look from back of set it is large metal box at extreme left side.

The blinking light is the unit trying to "Boot" up-----these have a problem where caps and a few other parts in that unit fail-----kits on the net are available----Mitsubishi no longer sells or services these units but PTS Electronics does repair them.

Let me know if you have questions and try disconnection of the front keyboard FIRST.

When I connect the tv to the stereo receiver the sound still comes through the tv in addition to the stereo speakers.

This condition sounds normal, often you need to turn off the speakers in the TV, via menu options on the TV.

I would strongly suggest to use the funds towards a new TV. It's most of the time a domino effect between service of your set and the next issue. Generally, once there is a problem sometimes it can set off a ray of other problems. I'd suggest to go with a newer technology. Invest in something current like DLP or even LCD flat panels are great due to no burn in, and much more affordable then they used to be. Another thing to be aware of is that by febuary 2009 everything is going to be all digital. What does that mean to you? Or your current rear projection set? It means that you would have to invest in an expensive converter box that would switch the signal from analog to digital in order to get any signal. That is why you see an enormous drop in digital display prices within the past years or so, plus lots of online companies going out of business because they cant afford to compete with electronics anymore. I hope this helps. After seeing plenty of TV issues within my 7yrs of experience in selling digital displays online...I think this is a much better route to go! Take care and good luck!
