One of my customers had the same problem. So last night, I took it apart and found a cold solder connection on a coil that had white goop on it. Goop is usually put on coils to stop oscillations. This is probably an inherrant problem. If you tap the back of the monitor with the back of a screwdrive, it should start working for awhile. Take it apart and take the shield off and do the same till you find the loose component. Don't hit it too hard. When you find the loose component. If you move the component back and and forth, it should work and not work. Take the board off and re-solder the component. Put the board back on and tap it lightly and see if you got the right component. If not repeat the proceedure until it works or pitch it...

SOURCE: Monitor Barely readable and dark but display is correct

We have about 20 of these at work. Four of them went dark, to varying degrees, in the two years they were covered by warrantee, and were sent back to the factory for repairs. Since then, eleven more have gone dark. I finally got around to looking at them a few days ago. I have repaired five so far, and in every case it has been the same cause.
The capacitors on the inverter board are burning out. There are two 470uF, two 1500uF and a 1000uF that are not holding up.
Costs about 4 bucks for replacement parts at digikey; qtys and Part numbers are:
2 PN #493-1561-ND
1 PN #565-1664-ND
2 PN #P13124-ND
It takes about an hour, and minimal skill with a soldering iron to fix.

SOURCE: NO GUI displayed

I had a similar problem with my Denon 3808 after it had the protection circuit tripped. First all I would get is a blue screen with sound, then after powering the unit off I got the display back, but all of the on screen GUI menus were gone. I could tell that the menu button worked because display located physically on the recever worked. I reset/rebooted the system (follow the directions in manual) and everything came back. Be aware by resetting the system any customization you have done will be lost. Hope that helps

Its because the pioneer does not display menu options through hdmi. You have to hook up basic yellow composite to monitor out.

If your oil is at the correct level, then the oil level sensor is not working correctly. If your oil level is low, then you need to fill it to the correct level

Oil comes out from muffler

I am guessing that this is a 2 stroke. If so, you must make sure you are mixing the oil and gas ratio correctly. Two much oil and it will smoke alot and run out the exhaust in the form of watered down oil. If the mix is correct, you may have a a bad ring.

Need to know wat oil i use, coz the oil light is on

The oil light is not an indicator that the oil level is low, its is an indicator that your oil pressure is low.

A dirty oil filter will make your engine loose oil pressure.

Of course no oil in the motor will also cause no oil pressure.

If you have the correct oil level and a new oil filter, and your oil light is still on.

Check that your oil pressure switch/sensor is working.(your oil light wire will go to the switch/sensor).

If your oil level is fine and the oil filter is clean and the oil light switch/sensor is good and the oil light still comes on, that is a sign that your oil pump isn't working correctly, and would have to be taken apart to see why.

Check the simple and less expensive stuff first, hopefully it will be one of those

Also, try starting in safe mode and verify Monitor is able to handle the display settings resolution

Pioneer vsx-819H: MCACC setup won't display on tv

I would say check the cable version not everyone knows this but there are different version HDMI cables such as 1.0,1.1,1.2 and the newest 1.3 cable these are band-with depended cables and if you use a lower version this should work if not you might have a issue with video.

Other then that you might have a issue with the unit if all other signals are working on the monitor.. Ruling out this will be hard if you do not have another monitor to test it on. I would be conducting a test on other output monitors and see if you get any results.

please press the accept button as I worked hard to answer you question.

Btw, I’m available to help over the phone in case u need at

Tv reception on handheld Sony Watchman in Feb 2009

The old Watchmans are analog. If plugged into a digital cable/dish system it will scan in UHF and find the working channel than can be conrolled by your digital remote control. As far as taking it out on its own and working off the external antenna...those days will be over. Sony will have to manufacture digital Watchmans.

Defect ASUS V8420 ?

I don't understand, please explain more:

0) What kind of a monitor is it ?

1) If the monitor is NOT plugged into a working video card,
it should blank out or display some sort of a
"NO SYNC" or "NO SIGNAL" or "UNPLUGGED" warning.

The power light may also flash or show a different color.

2) If the monitor is plugged into a working video card,
it should wake up from the inactive power-saving mode
and display the desktop.

3) If the video card is malfunctioning, or if the windows
video settings are set outside of the monitor's sync limits,
the monitor may turn off or display a warning message,
such as:

No sync, Out of range ... etc.

4) The repair situation (3), reboot windows into
safe mode:

a) Press Hardware Reset

b) After the power-on self-test (POST) and memory check
press and hold the F8 Key

c) Select Safe mode

d) Login to windows at low resolution

e) Right-click on the desktop, chose:

Properties -> Settings -> Set the correct resolution, apply
Click advanced -> monitor -> set the correct refresh rate.

Reboot normally

Hope this helps


PS, some monitors have dual inputs: VGA or DVI
make sure the correct input is selected, depending
on your cable (VGA is a 15 pin "D" connector,
DVI is a larger connector with many more FLAT pins)

Also some video cards have multiple outputs, which are
activated only if a correct monitor is attached BEFORE

Out of range

Try lowering your refresh rate from 85hz (or higher) to a lower value around 70hz.
This usually will correct out of range issues.

Device not installed properly message

Try this:

Go to Device Manager, right click on the monitor, choose uninstall, reboot the computer. When Windows starts up again, it will look for a driver(s), and might find the right one. If it doesn't, choose Cancel (this will set the monitor driver to Plug & Play Monitor or something like that which should be fine). Now, when you boot up you should not see that message again because the correct driver loaded or you chose Cancel.

Good luck.
