維修明基液晶顯示器資料

1:明基液晶顯示器能否正常開關機(指示燈沒信號為黃色、有信號為綠色)、仔細看屏上是否有變化,一般不仔細看是看不到顯示屏有變化的哦,看仔細啦。有變化或能夠正常開關機,表示主板完好,這樣的情況就屬於高壓板沒工作,沒點亮背光燈。

2:拆開機器,首先檢查高壓板(插220V的那塊板),螺絲鈕開,別偷懶,把電源板和主板都拆下,這樣比較好取下電源板、

3:測量C5707、FQU11P06(有的機器是用FU9024的)、是否損壞(擊穿)、如果損壞(擊穿),將他拆下來,在看.22/160V電容外觀是否有變形,如果有變形請更換,如果電容沒變形就不管他。

4:將損壞的器件更換新的,如果怕上電再燒,你可以講高壓線圈一起換掉,如果為了節約成本你就先不要換高壓線圈上電測試,如果在次損壞C5707就需要更換高壓線圈(大多數損壞C5707最歸禍首就是高壓線圈引起),

5:測量高壓板供電部分是否短路,如果無短路,請將保險(PF801)換上新的(一般損壞C5707,保險肯定損壞),如果你手上沒有此保險你就用細銅線連接起來,此保險為3A。

PF801請用電阻擋位測量,否則測量不准確。

3:更換C5707四隻(Q809、Q808、Q816、Q815) 4個高壓線圈(T001、T002、T003、T004), 2個FQU11P06或是FU9024 (Q812、Q805)。 PF801保險(此保險為3A)。

4:好啦,你現在可以開電看你的結果啦。



BenQ brand new high-voltage wire circle
BenQ LCD Controls circle / BenQ LCD accessories more high success rate, and easy maintenance, fault lower again!

Name : BenQ LCD
Name : LCD Controls circle
Model : specifications : 1J.26048.011

BenQ LCD accessories four small mouth lights of the high-pressure reverse pressure plate used for high temperature must Taiwan curbs are enameled wire system. With a small noise, power, brightness control in high-efficiency low-loss. Rapid cooling loop can be designed according to customer-specific products.
2 features the use of high-precision inverter line Rao, insulation and can be a long time. 3 to 1. Electricity use light line measurement of high-frequency currents. 2. Backlight voltage output of a sinusoidal waveform. 3. The backlight brightness and the same as the original high-pressure plate. 4. 1-2 4.1 filament output AC exchange through the export of Maintenance and Spec - CN5 link to the. 5 and storage temperature and Temperature temperature ranges : -5 -- 50 ℃ work humidity range : 10% -- 95% RH the backlight should be within the scope of the above, the following conditions can store 40,000 hours. Operating temperature : -10 -- 80 ℃ work Humidity : 20% -- 95 % RH

BenQ LCD maintenance information


1 : BenQ LCD can switch planes normal (no signal light yellow, green signal), Looking carefully at the screen whether there are changes, they generally do not carefully read the screen can not see a change, oh, look at carefully Matata. Change or switch to a normal plane, the main board intact, such a high-pressure situation on board is no work, no lights lit backlight.
2 : disassemble machines, starting with high-pressure plate (box 220V piece of the plate), a screwdriver button open, not lazy. Power board and put the Main Board are removed, this is a good Off Power Plate,
3 : Measurement C5707, FQU11P06 (Some of the machines are used FU9024), whether the damage (breakdown) If the damage (breakdown), he seemed to see the appearance .22/160V capacitance whether deformation, If deformation replace, if not capacitance deformation on regardless.
4 : damage to the replacement of the device, if the fear of electricity burned again, you can Controls circle together too, In order to save costs if you should not start for high-voltage wire circle -- testing, If the damage C5707 meeting on the need to replace the high-voltage wire coils (most of the damage to the C5707 is Controls 72.9% Circle aroused),
5 : measurement of high voltage power supply board whether short circuit, without short-circuiting I would be grateful if insurance (PF801) new ones (General C5707 damage, insurance will certainly damage), If you do not have insurance you connect with fine copper wire, this 3-A insurance. Please stop the PF801 power-measurement, measurement inaccurate.

Understand how maintenance of electronic maintenance steps friends

2 : disassemble machines, starting with high-pressure plate (box 220V piece of the plate), a screwdriver button open, not lazy. Power board and put the Main Board are removed, this is a good power to remove board.
3 : replacement C5707 4 (Q809, Q808, loops, Q815) four high-voltage wire coils (T001, T002, T003, T004). 2 FQU11P06 or FU9024 (Qingdao, Q805). PF801 Insurance (insurance for the three A).
