It is difficult to know for sure without some testing - by a trained tech who knows what its all about. Trial and error troubleshooting can sometimes be a poor way to solve the problem.

SOURCE: Red noise or flicker on bottom half a plasma screen

The old saying that a pictures is worth a thousand words could have been looking at this one... If the lower screen had been streaked in B&W or bands ran completely through the picture Old Drummer I would suspect the logic board also but that's lower y-board failure.

SOURCE: Philips Magnavox 37" LCD Flat

Disconnect the LVDS Cable that runs from the small signal board to the display panel and apply power,if the screen comes on,the Small signal board (aka Scaler Bd ) is the faulty board. other than that,all that's really left that has gone bad for me is the logic board.

SOURCE: my model tv is Samsung model LNS4692DX/XAA

Hello: The problem is on the power supply, there are two capacitors on the power supply near the plug that goes to the mainboard, these caps will look swollen at the top on them compared to the other capacitors in the circuit, if you know how to unsolder and resolder parts then this is a simple fix. The value of the capacitors on the board are 1000uf rated at 10 Volts, replace them with 1000uf rated at 16 Volts instead so this will not happen again. You can find them at any local electronics parts store, (Radio Shack) for instance..There will be two of them that look puffy at the top,they should all be flat so spotting them should be very easy...
Thks: Have a Happy Holiday...

Belkin router


I'm guessing that your laptops are using a wireless connection. If this is the case the first time you enter the wireless security key (password) it will be stored in the laptop so you don't need to enter it again.

To connect to the router, you need to open its associated web page which you will normally find by typing the routers IP address into the address bar in Internet Explorer. The usual default address for a Belkin router is 192.168.2.1.

Once you connect to the router you should be able to access all the security settings from the Belkins main menu.
