    My husband is a jack of all trades and actually used the contraption that indicates if power is goning through there was a power source, but just not turning on. So if you could help me with your last solution in replacing the fuse i'd like to go with that. where is it located?

  • dianeelk Mar 05, 2009

    can this be fixed or replaces by ourselves or do we still need to haul it to the repair shop?

The projection bulb  is gone.  When the red indicator light flashes, it is always the bulb. if it does not flash then the circuit board needs replacement its a costly issue to replace the board. replace the bulb which is located internally on the ballast board side first and check out.to know if the bulb is faulty check out the filament in the bulb it will be burned out or broken in between. the model is quite different but will give you fair idea on replacing bulb check out the link below by clicking it.

The problem canb be a blown capacitor on the power board, the TV must be inspected internally and tested toroughly to find out the cause of the problem.

There can be many possibilities for this problem.please mention any more detail.as from this status it indicates that the circuit got short in between and so there is no power in the tv or its not turning on.if familiar with the technical knowlege of using multimeters and soldering irons and continuity you can check out the tv main board and power supply area but if not familiar its risky to check just get it checked at professional repair shop as its woth getting it fixed only after getting the estimated cost from the service center .

Ok, if you have preformed a hard reset by unplugging and it still isn't powering up, its usually a blown bulb that has tripped the protect mode. you will have to replace the damaged bulb before it will power up.

    if you are getting a blinking light on the control panel, this is usually a pcb main issue. this will require service by a tech. if you are experienced electrician, you can disassemble and preform a break point test on this board to locate the issue. its probably a IC issue.

TV stopped working.


After you remove the back cover inspect the power supply board for swollen or bulging capacitors. Pull and check any capacitors that you suspect to be swollen. Next, look for a sticker in the back side of the TV set. Use the values you find on the sticker to calibrate the voltages on the power supply board.

Tomtom GO 910 GPS stopped working


Mine is about three weeks old and just did the same thing. I ahd been using it while walking in a town in Germany. So I did not even have power/docking or PC problems.

I reset the unit with a paper clip. Look in the mounting opening at the lower rear of the 910, there is a small cut out. press this carefully, mine is now back to life and did not even lose my 'recent' list.

Olevia 747 won't come on


I had the same problem with a 437. It just shut off one day and I could never turn it back on again. I called Syntax Brillian and they told me the mother board was probably shot. They sent me a new TV and took the damaged one back.

I can't turn the camera on anymore


I dont have a definite solution, but I would;

- clean the power contacts on the battery and the camera with a moist Q-tip

- leave the battery out for a day or so, maybe more if you have time. Make sure the battery is charged again (maybe just put it on for an hour or so) and re-try.
