Connecting Compaq Presario CQ40 to LCD tv Toshiba REGZA '32'

This TV has a PC interface VGA (HD-15) , so all you need is get a VGA to VGA cable to plug between the VGA output on the PC and TV.
On the PC select the display as external monitor.
On the TV pick the PC input as required input, not the TV tuner.
Here is the manual.

compaq is worst......i m also having the same problem with the LCD of my laptop compaq presario CQ40....wat to do????

Hello

With either the PC IN or HDMI connection, you can watch

your computer's display on the TV and hear the sound from the
TV's speakers.

When connecting a PC to the PC IN terminal on the TV, use an
analog RGB (15-pin) computer cable and a PC audio cable.

To use a PC, set the monitor output resolution on the PC

before connecting it to the TV. The following signals can be
displayed:

Format Resolution V. Frequency

VGA 640 × 480 60Hz

SVGA 800 × 600 60Hz
XGA 1024 × 768 60Hz

Other formats or non-standard signals will not be displayed

correctly.

Note:

• The PC audio input terminals on the TV are shared with the
HDMI-1 analog audio input terminals
• Some PC models cannot be connected to this TV.
OK.

You may find that as Mac uses a different standard for VGA output, the sync will be on a different pin not recognized by the TV.
You may need to purchase a Mac to IBM adapter from a computer store.
Hope this helps.

Consult the Sharp Manual for VGA specifications and set the Compaq VGA to match accordingly.
