Control panel Lately, the control panel locks up; both manual & remote. To date the problem can be resolved by unplugging & restoring power (reboot). I expect the panel may die completely soon.

Try unplugging, remove battery, plug in, reboot, and run a System File Checker using this procedure: http://support.microsoft.com/kb/929833 AND, test the HDD use this procedure: http://windows.microsoft.com/en-us/windows-vista/check-your-hard-disk-for-errors If this is a recent event do a System Restore to a date before this issue. Or a Factory Restore. Have you cleaned the fan, vents, and heatsink lately? Has there been ANY damage? Drop? Post results

Remove ALL media, DVD,CD,USB, Unplug, remove battery, Plug in, reboot and Do a System Restore to a date before this issue. Have you done ANY Updates or Upgrades lately? Post the Compaq Model and the OS you are using.

If you do not have the owner manual either Google the model number for it or contact LG.

This set may have a lock out feature that locks out both the remote and the buttons on the set.

Also if have not tried it--unplug set for a while and power back up which may allow it to reboot.

If it will not shut down with the remote (manual power also?) it is a microprocessor issue--if have not tried it unplug it and or a box if connected and wait--plug them back to allow them to reboot.

The remote can be tested to see if it is good but will not cause the scanning issue etc.

Switch On your PC/ Laptop and log in to windows.

Now you will find one Month Calendar window with Dates below, go to the previous month by clicking the '<' sign in the upper left hand corner of the Month Calendar and select any date that you see in Bold.

Note: It is better if you could remember from which date you are facing the issue, try to select a date prior to that date.

The detail of that particular date should show "System Checkpoint" and time on the right hand side box. Select that date.

Now, Click on Next and System Restore will start and windows will take a reboot.
