Abstract
A display device is assembled so that access to the main PCB assembly is simplified. The rear housing covers the assembly; and once removed only the top shield has to be removed to expose the top of the main PCB assembly. After the top is removed the stand and bottom bracket can be easily removed, to gain access to the bottom of the main PCB assembly. This display device allows for the testing, repairing, and replacing of individual components of the main PCB without having to remove any of the side PCB assemblies. This allows repairs to be made in less time, at a lower cost, and increases the market competitiveness of the display device.
Claims22
A display device, comprising:
- a stand supporting a bottom bracket;
- a printed circuit board bracket supported by said bottom bracket, said printed circuit board bracket supporting a main printed circuit board assembly and having a plurality of apertures exposing a bottom side of said main printed circuit board assembly;
- a lower frame attached to said bottom bracket and said printed circuit board bracket;
- a first side printed circuit board assembly attached to any one of said printed circuit board bracket and a second side printed circuit board assembly;
- a housing having a first portion and a second portion, said first portion attached to said lower frame and covering a cathode ray tube;
- said second portion of said housing covering said main printed circuit board assembly, said first and second side printed circuit board assemblies, said printed circuit board bracket, and said bottom bracket;
- a top side of said main printed circuit board assembly being exposable without removing said side printed circuit board assemblies, by removing said second portion of said housing;
- and
- said bottom side of said main printed circuit board assembly being exposable without removing said first and second side printed circuit board assemblies, by removing said second portion of said housing, said stand, and said bottom bracket.
A display apparatus comprising:
- a front case for housing a cathode-ray tube on which images are displayed;
- a main printed circuit board assembly installed beneath said cathode-ray tube;
- a lower same secured to said front case;
- a printed circuit board bracket secured to said lower frame for holding said main printed circuit board assembly, and having a plurality of apertures exposing a bottom side of said printed circuit board assembly;
- a bottom bracket having first assembling means for coupling with said printed circuit board bracket;
- and
- a stand supporting said display apparatus and having a second assembling means for securing to said lower frame while being interlocked with said printed circuit board bracket and said bottom bracket.
A process for assembling a display device, comprising the steps of:
- attaching a first portion of a housing to a cathode ray tube;
- fastening a lower frame to said front portion of said housing;
- fastening a printed circuit board bracket and a bottom bracket to said lower frame, said printed circuit board bracket supporting a main printed circuit board assembly and having a plurality of apertures exposing a bottom side of said main printed circuit board assembly;
- fastening a first side printed circuit board assembly to one of said printed circuit board bracket and a second side printed circuit board assembly;
- sliding a second portion of said housing over said first and second side printed circuit board assemblies, said main printed circuit board assembly, said printed circuit board bracket, and said bottom bracket, said second portion of said housing being removable to expose a top side of said main printed circuit board assembly without removal of said first and second side printed circuit board assemblies;
- and
- slidably engaging a stand to said bottom bracket, said stand and said bottom bracket being removable to expose said bottom side of said main printed circuit board assembly without removal of said first and second side printed circuit board assemblies.
