    there will be relay that controls the power supply to the main display device...
    if the relay is faulty in power supply will not be passing through the areas which it is necessary to pass

  • dewan nafees ahmed Feb 26, 2008

    ""Relay will only be in "broadcasting" of AM and FM signals.""

    any rule??

    relay is a protection device. and this is the one which is responsible for tripping of the circuit when there is some short circutiing in the board.

    this type of protection can be found in power boards of many devices.

    am i wrong?

  • dewan nafees ahmed Feb 26, 2008

    relay is a basic component used in all circuits for protection of power circuits. if the relay is not maiking that "tick" sound then what component you suppose will make that sound?? capacitors??

    i dont think so...

    anyways good luck.

    thank you.

    hi there, red light flashing means a shorted parts on the unit. You will need to check the horizantal section for any shorted it. If you find anything faulty note the part number or name any information you can provide about the faulty part and i will tell you how and where you can get it.

  • eagle338
    eagle338 Feb 13, 2008

    probably some faulty capacitors

  • eagle338
    eagle338 Feb 13, 2008

    Sorry for being vague... what i meant was you have to turn off the power supply and open the set. Using a multimeter look for faulty capacitors in the horizontal sweep section or any other open circuits. Please note that this is a rather difficult task if you are not familiar with electronic circuits and if this is the case i would leave this job to a tech!

  • eagle338
    eagle338 Feb 13, 2008

    Yes that is the horizontal sweep and sure thing you can let me know so that we can proceed further..

  • eagle338
    eagle338 Feb 22, 2008

    It is a problem in the power supply section.. From The readings you have provided The problem has got to be in the power supply section. You will have to replace one or more faulty capacitors which are causing that click sound.. I would advice you take the help of a tech to get them replaced. Repairs would run you about 75$.
    Good luck!

  • eagle338
    eagle338 Feb 22, 2008

    Sure thing welchco. Hello sweet rascal there will be no component called relay in televison. Relay will only be in "broadcasting" of AM and FM signals.

If it is not a bad solder connection that comes and goes as you flex the set or tap it with your hand, then it is likely the capacitors on the PSU Board that need replacing.

Dual Monitors. #1 works fine. Plug inb #2 and #1 goes to sceeen saver and #2 stays blank.


Both monitors must be plugged in when the computer is started for the second monitor to be detected, and you must configure the second monitor once the computer has started
In windows XP: control panel -> display -> settings tab -> select second display -> check "extend my windows desktop onto this monitor" -> click apply
In windows vista/7: control panel -> adjust screen resolution -> select second display and then under "multiple displays" select "Extend desktop to this display"

I replaced lamp and picture shows well except at


Light from the lamp is getting itnto the top inside of the set Just changing the lamp should not cause this problem. I've seen this where someone has cahnged the light engine and did not reinstall the foam gasket aroun the lense . But any way look for an opening from the lamp area into the upper chamber where the mirror is.Light from the lamp should only go into the light engine and not into the upper chaber except through the projection lense.

I have similar problem. Sometimes it will show only a blank screen. Just unplug the AC cord, wait a few seconds and plug the AC cord back in. This will reset the processor and the picture is back. It happens once a month. Not a big issue to call warranty service.
