Now all three lights are blinking and it clicks when i turn it on, but no sound or picture... Looked at the bulb, looked fine, but...... Please help.....

    Hi again,



    If you hear any click sound then these are the following possibilities:





    ONE: The protection circuit is shutting the set down when you turn it on - to avoid further damage to the set.



    TWO:
    The reason for the shut down is due to the protection circuit detecting
    excessive current in one or more sections of the tv.



    THREE: The
    clicking sound is the ON relay getting shut OFF by the protection
    circuit. The thumping sound in the speakers is from the power supply
    coming up in voltage a little, and then shutting down.



    FOUR:
    Number one reason for auto shut down in big screens is loss of high
    voltage. Number two is defective deflection amplifiers (horizontal or
    vertical amplifiers).



    FIVE: These repairs are not something you can do at home; they require the service of a trained tv tech.

    Goodluck,

Look at the Large Lamp fan and if it is not rotating it is bad and needs to be replaced. If is ok then check the other two smaller fans. You do have a bad fan.

Is coming alot of bright spot all over the screm like a little point isee the channels whith the spot


These are failing pixels in the matrix. Eventually the screen will not be viewable.
The screen is made of millions of points of l;ight called pixels They turn on and off to create what you see on the screen. When they fail they become minute white spots.

My HL-S4666W's screen picture freeze whenever I turn it on


If the tv has a built in discoder, it is the decoder at faulty, bypass the decoder using a dvd player, and if that plays then it will prove the decoder fault, the dvd signal is stronger than an external source, oh, by the way, unplug any source of dish/arial etc to the decoder, giving the dvd master control of the tv

Installed new lamp/how to reset the lamp hour meter on samsung (HL-S4666W)


Here is the procedure for resetting the lamp timer.

This is a quick reference guide to show you how to reset your Samsung DLP TV’s lamp hour meter or hour counter. Resetting the counter is a very simple procedure.
Begin with the TV powered off.
Point your remote towards your TV.
Press:
Mute + 1 + 8 + 2 + Power.

Your TV set should now say “Loading Factory”.

Browse down to “Option” then press Enter (or the right cursor button).

NOTE: The Mute+1+8+2 buttons needs to be pressed down consecutively and fairly quickly. If your TV does not enter the service menu after using this combination, you can substitute MENU instead of MUTE. This seems to work for some sets. Also, the right cursor arrow also acts as the ENTER button, so try it if you’re having difficulty with the ENTER button.
To exit the service menu, hit press the EXIT button or just turn off your TV (remember not to turn on your TV immediately afterwards!).

I hope this information allows you to resolve this issue.
If I have helped you, please help me, and rate this suggestion the highest FixYa rating. (Two Thumbs Up) If you cant rate this post with the highest rating, then please comment to this post and I will try to help you further.
