TV will not turn on. Pressing the power button produces an audible click from the rear of the unit, but no other indication of power.

The click you hear is the power relay engaging. If you get no further indication of any cactivity or you jsut hear a second click, there is an internal problem and the protection circuits are shutting down the set. Was there any symptoms prior to the set being dead? If not, the most likely cause is either a shorted horizontal output transistor or convergence ICs (assuming a CRT based set). Usually DLP or LCD based projection sets have indicators on the front that will flash when there is a problem with the lamps. If you can post the make and model, I can provide a more detailed explanation and possible fixes.

Thanks,
Dan

It sounds like a faulty component on the power supply. Capacitors can cause that click you are describing so if you start your check there you might find the problem pretty quickly. Also check resistors near the faulty cap as these could have been taken out. If you are not able to check this yourself entrust a competant technician. Good luck.

If the front panel indicator is on and pressing the power button does not produce results, there could be a blown fuse internally or something wrong with the power supply

Can I turn the beeper off on the end of the washcycle on the DDY062 Hoover dishwasher. I want to put it on timer delay and dont want to be woken in the middle of the night.


These are the instructions taken directly from the DDY062 manual:
Alarm mute for the PROGRAMME END
The alarm for the programme end may be muted as follows:
IMPORTANT The dishwasher must be ALWAYS off before start this procedure.
1. Hold down the "PROGRAMME SELECTION" button and at the same time switch on the dishwasher by pressing the "ON/OFF" button (a brief audible signal will sound).
2. Keep the "PROGRAMME SELECTION" button pressed for at least 15 seconds (during this time, 2 audible signals will sound).
3. Release the button when the second audible signal sounds (3 "PROGRAMME SELECTION" indicator lights will come on).
4. Press the same button again: the 3 indicator lights (which indicate that the alarm is activated) will start flashing (to indicate that the alarm is off).
5. Turn off the dishwasher by pressing the "ON/OFF" button to confirm the new setting.
To turn the alarm on again, follow the same procedure.

Okay, so my Panasonic PT-43LC14 went black in mid show last night. The bulb is approximately 18 months old. The LED indicators upon Power On are; Power LED blinks green for approximately 70 seconds; Then...


Check the bulb again and look at the root of where the main stem comes out inside and be sure you don't see any bubble like appearence around the stem at the bottom there. If you do see this then the bulb is bad. Otherwise try this: Hold volume down on front of unit and pip on remote for about 5 seconds. Message will come on screen that timer has been reset to zero. This sets the lamp timer to 0

Vizio takes a few clicks of the power button to turn on.


This is an indication of leaky filter electrolytic capacitor on the power supply section.

A dried up main filter capacitor or other filter capacitor in the power supply will produced an out-of-regulation condition until it warms up.The symptom will get worst if not isolated.


I've advice you to look for a qualified technician to replaced the said parts.But first check if your unit is under warranty then avail it because the manufacturer of your unit will fix it for free or a little charge only.


Thanks for using fixya.
