Magnum PF21500, Service Manual

CAUTION: 

FOR YOUR PROTECTION, THE FOLLOWING PRODUCT SAFETY NOTICE 

SHOULD BE READ CAREFULLY BEFORE OPERATING AND SERVICING THIS TV SET. 

1.3.1 

Many electrical and mechanical components in this chassis have special safety-related characteristics. 

These characteristics are often passed unnoticed by a visual inspection and the X-ray radiation protection 

afforded by them cannot necessarily be obtained by using replacements rated at higher voltages or wattage, etc. 

Components which have these special safety characteristics in this manual and its supplements are identified by 

the international hazard symbols on the circuit diagram and parts list. Before replacing any of these 

components read the parts list in this manual carefully. Substitute replacement components which do not have 

the same safety characteristics as specified in the parts list may create X-ray radiation. 

1.3.2 

Do not slap or beat the cabinet or CRT, since this may result in fire or explosion. 

1.3.3 

Never allow the TV sharing a plug or socket with other large-power equipment. Doing so may result in 

too large load, causing fire.

on, modified, cut or pinched, particularly at plugs. 

1.3.5 

Do not place any objects, especially heavy objects and lightings, on top of the TV set. Do not install the TV

Service personnel should observe the SAFETY INSTRUCTIONS in this manual during use and servicing 

of this TV set. Otherwise, the resulted damage is not protected by the manufacturer.

1.4 SAFETY SYMBOL DESCRIPTION 

The lightning symbol in the triangle tells you that the voltage inside this product may be strong nough to 

cause an electric shock. Extreme caution should be exercised when working on the TV with the back removed. 

This is an international hazard symbol, telling you that the components identified by the symbol have 

special safety-related characteristics. 

UL 

This symbol tells you that the critical components identified by the UL marking have special safety-related 

characteristics.
