If you are concerned about humidity and switches, spray them with DeOxit. You can get it at Radio Shack.

ON/Standby light on Sony VPLDX 120 flashes 4 times.

These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices.
If blinks continue without any pause, the main board is faulty.
Search the site by type in the "brand name" to your device, in the "Search box at the top right of the display window of the Homepage" to get gathered related posts.

If your TV wont turn on using the power button key on the remote control and on the front panel, this is an indication of fault either on the power supply board or the main board. This kind of symptoms is not a DIY and needs to attend by a qualified Technician to troubleshoot the said boards and isolate the faulty parts.

You have mentioned that you've only used it for 4 months, then your unit is still under warranty period. Don't attempt to open the back cover because it will void the warranty, avail it because the manufacturer will fix it for free or replaced it with a new one.

I my projector is new one used for 4 hrs, when i try to turn it on it just has a blinking green light. Please help Solve It! .

The blinking green light means the unit is either Powering On (Warming Up) or Powering Off (Cooling Down).

Powering On the Projector
1. Remove the lens cap.
2. Securely connect the power cord and signal cable. When connected, the ON/STANDBY LED will turn Amber.
3. Turn on the lamp by pressing " " button either on the top of the projector or on the remote. The ON/STANDBY LED will now turn Green. The startup screen will display in approximately 10 seconds. The first time you use the projector, you can select your preferred language from quick menu after the startup screen displays.
4. Turn on and connect the source that you want to display on the screen (computer, notebook, video player, etc). The projector will detect the source automatically. If not, push menu button and go to "SETUP". Make sure that the "Source Lock" has been set to "Off". If you connect multiple sources at the same time, press the "SOURCE" button on the control panel or direct source keys on the remote control to switch between inputs.

If you are still unable to get the unit to turn on, try unplugging it for 10 minutes and plugging it back in. If it still ceases to work, contact Optoma here:

The problem with my marshall ma100h amp is that out of the box brand new it stopped working within a few days. Earlier I turned on the amp power switch and let it warm up. About a minute later I kicked on...

Brand new? Take it for warranty repair IMMEDIATELY... don't mess with it !!!

The only thing for you to check is that you did not turn on "STANDBY" as this shuts down the power amp and the capacitors will bleed off and sound will fade. Try switch in both states before complaining

ONLY use the amp in STANDBY for a brief period (20 seconds) to let the tubes warm up... Leaving in STANDBY for a long period straains the input filter capacitor. If you are done with using the amp, turn it off...

My pioneer vsx-519V-k amp won't turn on. Just bought it about 4 months ago. we were using it with music and a microphone when it conked out and won't turn on anymore. Have checked the power source, the...

Have you checked within the set, the fuse and if the standby circuit is working. thre could be a failure of this sub votage which is required for the switch on of the main power. If you do not have any standby indication you must check this section, however if you arre getting the standby you would have a failed output or a shorting that is triggering the error amp to swtich off. If you are familiar with the circuits you can check but I would suggest that since you will need more experience to look into the main board for tracing the fault. In such case check for the service centre nearest to the place you are in using a google search for Pioneer - Audio systems- sevice. Helpful I hope. Good day.

What is the proper proceidure to set exercise timer on a briggs generator model # 01938 and what year was this model manufactured? thank you

This link will take you to their site where you can download their manual.

Setting Exercise Timer
The Home Standby Generator is equipped with an exercise
timer that will start and exercise the system once every
seven days. During this exercise period, the unit runs for
approximately 20 minutes and then shuts down. Electrical
load transfer DOES NOT occur during the exercise cycle
(unless an utility power outage occurs).
A switch on the control panel is labeled “Set Exercise”
(depicted on page 10).The specific day and the specific time
of day this switch is pressed is programmed into the
control board memory.This date and time is then used to
automatically initiate the system exercise cycle.
To perform the Set Exercise procedure:
1. Choose the day and time you want your Home
Standby Generator to exercise.
2. On that day and time, set the AUTO/OFF/MANUAL
switch to OFF.
3. Press and hold down the “Set Exercise” switch for two
4. Set the AUTO/OFF/MANUAL switch to AUTO.“Set
Exercise” is complete.
For example, if you press the “Set Exercise” switch on
Sunday morning at 10:00 AM, the unit will run an exercise
cycle the following Sunday at 10:00 AM (+/- 1/2 hour).
NOTE: “Set Exercise” will only work if the unit is in the
Automatic mode and this exact procedure is followed.The
exerciser does not need to be re-set if the 15 Amp fuse is
removed or changed.The exerciser will need to be re-set if
the 12 Volt DC battery is disconnected.
If you want to change the day and time the unit exercises,
simply perform the “Set Exercise” procedure at the exact
weekday and time you want it to take place.
• To prevent possible injury that might be caused by such sudden
starts, always set the AUTO/OFF/MANUAL switch to OFF.
• Remove the 15 Amp fuse before working on or around the
generator or transfer switch.

Bought a used Martin Logan Dynamo subwoofer a couple days ago and have a very loud hum when the ac cord is plugged in, even if the speaker is not connected to an audio source. The "hum" can be heard in any...

Neither the amp or the sub have grounded power cords.

I have discovered the ML Dynamo takes about 30 minutes to switch to standby in auto mode.

With speaker level inputs connected to the Onkyo A807 amp, both units powered from the same wall outlet, Dynamo sub on Auto, the sub hums for about half an hour after the Onkyo is switched off, then the sub goes quiet. Not so good.

I connected a bonding wire between the two units on 3_7_09. If I smoked some old audio gear I could just look at that as an opportunity, right?

Works fine. Now I have the ML powered from the wall and working normally.

Monitor will not turn on including power switch

I suspect the power supply for the monitor. Try a power supply from a working monitor. If you have a used computer store nearby, take your power supply to them and try it on another monitor.

There is no need to turn off a monitor using its power switch. Monitors automatically go into standby mode when they are not receiving a signal. In standby mode they use less than one cent of electricity per day. If saving electricity is your goal, raise the temperature in your home by a degree and run the air conditioning less.
