Horizontal problem Sir I went to service a HP 1024 monitor. the problem is the horizontal adjustment switch is not working even i changed the front switch. Rest of all controls are functioning properly.

CRT monitors are basicaly the same as TVs which are along with micros and rabid rotweilers the most dangerous thing in a house to service. They can store very high voltages even after plugged out, enough to kill. Take care and don't go any further unless you are aware of all the safety issues. If you want more information on the required equipment and SAFETY PRECAUTIONS, go here: http://www.repairfaq.org/ Probably, your GS monitor uses little 3-position 'tab switches' which can be reached from the rear of the main circuit board. One of the switches should set vertical position. You will need to remove the case. You will need to unplug the cable going to the side-mounted controls and, then, once the case is off, remove the side-mounted controls from the case and reconnect to the circuit board to do the adjustments. This is kind of a hassle; so, while the case is off, you may want to check the Focus and Intensity settings (slotted shafts on the black HV module). Also, this is a good chance to dunk your case in a sink of soapy water. NOTE --> Be sure to wear goggles/ work on a non-conductive table surface/ have a fat magazine ready to support the circuit board/ avoid stressing the CRT neck/ stay away from the HV anode lead (plugged into the back of the CRT) and avoid touching the back of the CRT. Good luck
