Question about ViewSonic NextVision N2010 20 in. LCD Television
Hello, I have a Viewsonic flatscreen LCD TV that is out of warranty. Just recently when I turn on the Power from either the remote or on the TV itself it would power up for approx 3-4 sec's then power down. If I hold the power plug firmly into the socket on the TV it comes on for a minute or so then goes off again. Is there a known problem with the power supply on these LCD TV's? Is there an 'easy" way for me to fix it or am I screwed and have to but a new TV bearing in mind that this set is anly about 18 mnths old!! many thanks for any advice, dave
You have probably already resolved this, however if your TV is 32" or smaller it likely has bad capacitors in the power supply. If you try it once more take note of: Does the red standby light still come on? If so, unplug the unit and either replace the capacitors in the power supply or purchase a new power supply from a Viewsonic service centre. Don't keep plugging it in and trying to get it to work in this condition or you'll completely blow the supply. If the standby light no longer comes on and the tv will no longer power up, the power supply board is toast. Get a new one and install it (they are pretty easy to install, unscrew the remove the back cover, remove the shield covering the boards, unplug two plugs going to the power board and remove the board. Install the new board and reassemble.
