Xantrex power inverter 1750


The 14 AWG Positive wire should be connected to one side of a 30 A relay (typical fog lamp relay available at most automotive stores). The relay's other 30 A contact should be connected to the battery positive post via a 10 AWG (up to 6 ft/2 m)

Power light just flashes no sound or picture


Solution no_1
by Realist 2006
Member since:April 09, 2006Total points:15,673 (Level 6)Best Answer - Chosen by AskerIt is almost certain that the power supply unit is in what is termed Hiccup mode which is simply the power supply shutting down when a fault is sensed , of course when the set is switched off the fault can not be seen so the set switches on again whereupon the fault is sensed again so the set switches off , ad infinitum , hence the flashing power light ! Usual cause is short cct line out transistor or transformer . That my friend is about as far as one can go using guess work

Soltion No._2
The problem is either the power/inverter board or the lamps inside the LCD panel. if one of the mini florescent lamps fail to start up the inverter section of the power/inverter board senses this and shuts the set off and registers the error. If none of the lamps light up, then the board has to be bad (not all of the lamps can go bad a the same time). These lamps are similar to those in shop lights (just smaller) and eventually they will go bad. When a lamp fails to light up then it could be that stage of the inverter or the lamp. A technician is neede to determine which is bad.Knowing this, here is a way to temporarily over-ride the shutdown, you should do this in a room that is as dark as possible to see what the back lights are doing during the couple seconds they attempt to light up. If it never lights up, then you can replace the board yourself . If it lights up and shuts back off then you need a technician to determine if it needs a new panel or the board.
To over-ride: unplug the AC cord, press and hold the [volume down] and the [input] buttons on the TV keyboard while plugging in the AC cord. hold these buttons until the indicator turns green, then release them. when watch what happens. If the green light never shows then do again (you will need to unplug the AC cord for over 30 seconds between each try).

My bravia kdl52nx800 shuts down right after turning it on. flashing 6 times


Very common problem the 6 blinks is indicating an issue with the Inverter. Replacing the inverter should solve the issue. You should be able to get the Inverter from www.tvcircuitboards.com

I have read another solution which may indicate the light engine has failed and will likely need replacing. The cost is quite expensive. $1500 range and apparently the part is no longer available from LG. Best you might do is get an estimate to repair just to be sure.

After replacing lamp tv cuts off immediately after being turned on


When the set shuts off, there should be some indications on the front such as teh lamp or temp indicators. Are any of those lit or flashing? Recheck to make sure that all access doors are completely closed. There are interlocks that will shutdown the set built in so that if the doors are not closed, the set will shut down.

For further information, please provide us with the model number so we can supply details specific to your set.

Thanks,
Dan

Tv no picture makes sound like cricket three times, green light on then shuts down and lamp light comes on, most of the time but sometimes just shuts down completely


lamp light flashing? possibly going out and needs replacing. google search the model number and lamp replacement, you might get lucky and find a replacement. around $250.

I have a GemmaTech Durabook D15R Series. I was


You could have a defective screen, either a faulty inverter or a CCFL lamp - follow this to determine the fault.

Defective CCFL backlight, it may have the following symptom:
  • Screen flashs on red/pink and off.
  • Picture stays on in red and slowly be come normal.
  • Picture flickering with dim display.
  • Picture flickering on and off.
All these symptoms indicate that the LCD backlight lamp (CCFL Lamp) has reached the end of the life and all you need to do is replacing the CCFL lamp

Connect an external monitor to your laptop and power it up, if you see the normal Windows images then the video card and laptop is OK and the problem is definitely the backlight.

Dim image and/or dark display on the laptop's LCD screen indicates a faulty LCD backlight and it could be the inverter that supplies high voltage to the CCFL lamp or it is the CCLF lamp is nearly burnt out or burnt out, most likely this is the case.
The inverter can be replaced easily but the CCLF lamp is more time consuming and requires soldering skills.
Check out www.lcdparts.net for parts, repair service and DIY info.
