Professional opinion guidance understands projector primary failure
From;    Author:Stand originally

Do a business most be afraid of is to feel do not wear knack, this appear more heavy to dimension study at school want and clear, be less than a reason to be in than be being checked like bad finish of a machine, it is the business that how makes a person depressed. . . . . .

Projector serves as a kind of accurate telescope, everyman is familiar with not quite commonly, and general maintenance technician also can have the place that does not know. It is professional personage is aimed at all sorts of common breakdown that happen likely below, offer settlement means from train of thought, everybody can consult!

Temperature calls the police systematic breakdown

1, the trouble that fan breakdown and place of circuit of fan power supply cause
2, the trouble that all sorts of thermal resistor breakdown cause projector
3, advocate board breakdown of temperature control system
4, after bulb ageing, the quantity of the infrared ray of generation and ultraviolet ray is exorbitant breakdown
5, bulb offers the breakdown account of electric equipment

Bulb calls the police systematic breakdown

1, the cause that itself breakdown causes bulb
2, the account that bulb offers the breakdown of electric equipment to cause
3, advocate board give out light a lamp the breakdown of signal reason
4, the breakdown of the leakage of electricity of high tension line of bulb power supply reason

Show lack lubricious breakdown

1, the cause that the breakdown of line line causes data
2, the cause that circuit breakdown causes interface (AD9883, AD9884, AD9888, SAA7118, PW1231 changes method)
3, the breakdown of drive circuit is caused reason
4, the reason of the breakdown of image processing circuit (PW164, PW166, PW168, PW364, PW365)
5, skill of the judgement method of EEPROM breakdown reason and maintenance (software is brushed afresh write)
6, liquid crystal screen or color annulus breakdown reason causes trouble
7, polarizing board burn
1, the breakdown of share of umbriferous Electromechanical cause

Not have show

1, projector advocate board breakdown is caused breakdown
2, lighting system is caused reason
3, the breakdown of indication drive part is caused reason
4, the breakdown reason of chip of liquid crystal screen or DMD
5, the jotter indication to projector mode is incorrect

Image lack fidelity

1, factory of extensive go back to work is prefab mode
2, projector advocate board the reason of breakdown
3, the breakdown of control plate is caused reason

Image blurs

1, the adjustment of camera lens the place is wrong, adjust optimal position.
2, the malposition of lens adding up to light and optical component truly, optical component has all sorts of dirt, convex damage.
