A common fault with modern LCD TVs concerns the power supply, the remote power button or the TV on-off switch, i.e. the TV will not switch on. This can be caused by a poor switch contact or a fault on the power Printed Circuit Board (PCB).
The specification below provides the recommended improvements needed to improve product durability. They are ranked from bronze to gold based on the effectiveness of the change in improving durability, with bronze being the minimum and gold being the maximum.
Physical on-off switch; soldered connections; well-spaced components; power surge protection
PCB inspection to comply IPC610E and IPC-J-STD-001; contactless/electronic switches; surface mount technology
Ask for clear and specific evidence of meeting the requirements listed above, e.g.:
Improved reliability of components can reduce early returns and improve brand reputation which, in turn, can lower business costs and increase long-term sales.
To calculate overall cost savings for your business, use the WRAP cost/benefit analysis tool (currently in draft form and available on request).
Physical on/off switch on TV
On-off power switches are common and cheap. The significant cost could be in a revised moulding with associated tooling costs. Contactless/electronic switches are generally more expensive than those with physical contacts but far more reliable.
Surface mount technology
The use of surface mounted components could add a significant cost depending on the volumes made and production techniques available in the factory of choice.
Power surge protection
Surge protectors (varistors) are commonly available and the additional cost should be low.
PCB/switch testing and inspection
Any testing and inspection will add cost in terms of rig time and labour costs.
