Question about Sharp Aquos LC-37GD6U 37 in. LCD HDTV
Sharp AQUOS LC32GA8E the tv is connected with a sky box, dvd and vcr, when the tv is turned on the picture will display for a few seconds then go off, after tkaing the scart connection out and putting back in a number of times the picture will come on, however this is taking longer and longer each time.
Sounds like you have a bad panel. This ussually happens when a backlight lamp has gone bad and the inverter board senses this and sends a signal to turn the backlight off.

Tips for a great answer:
Get some double-screened satellite cable and fit a female TV plug to it (or a male plug with an adapter). Connect it to RF Output 2 at the rear of your Digibox. Fit a TV plug to the other end and plug it into your TV.
Temporarily disconnect the aerial feed from the Digibox aerial socket. Switch the Digibox on to get a picture on your main TV. The Sky Digibox normally sends its signal out on UHF channel 68 so go to the second TV and tune it to 68 (or tune it till it finds the Sky picture).
Now plug the aerial cable back into the Digibox. If there is now interference on the Sky picture on the second TV (or on the terrestrial channels) your Sky signal on 68 is causing interference. Press [services] 401 [select]* and set the RF output to a different UHF channel number. You need to connect it via a Scart lead on your main TV in order to see the menu.
*In the new EPG (April 2009) it's [services] 001 [select]
Try each RF output channel number in turn (21 - 69) and retune the second TV until you get clean pictures on the terrestrial channels and the Sky channel. Also check the picture from the VCR (if connected).
This is just a brief overview. If you need a real in-depth explanation you should read the "Piping TV Around the House" Ebook by satcure.
