The spare circuit diagram is not available, and since Benq is out of market, the service manual will aso be difficult to find.

Check all capacitors, looking for a bulged one, that is the most common cause for faults on PSU unit.

My CDJ 850 won't turn on.

If the standby light blink then it indicates a fault relevant to the processor.If the set is fully dead then the SMPS power supply can be faulty.

Since there is a possible short or leak in the circuit the output driver section can take in huge current to trip the SMPS or from advice from the micro processor. Remove the power plugs and make sure that high voltage sections are discharged of the potential stored in capacitors. Look for visible signs of leak or of busted capacitors. Look for bulged capacitors or damaged components- burnt or busted. Use a multimeter to check the continuity or shorting in components, if so detach from circuit and test . If the voltage builds up and the set power ON and then shuts up then the suspected section must be checked in detail.

The processor must have the +5 voltage to the function properly , the +B and secondary voltages also must be checked to infer the fault. Trace with caution and in running through the signal path , circuit trail.

Hello, I have a 28" BenQ

Good day!
The problem of your TV is in the back light.
Follow this procedure of troubleshooting to your problem.
  1. Open the back cover,remove all screws at the back.
  2. Plug-in the power cord then power it ON.
  3. Check the input supply of the inverter board.It should have 24vdc.
  4. Then if you have input voltage of the inverter board.Check the output of the inverter board it should have 500vdc so be careful its high voltage.
  5. When your inverter had a output of 500vdc.It could be the cold cathode lamp is busted replace it.
  6. If the inverter board have no output of 500vdc but it have a input of 24vdc.Replace the inverter board.

Thank you and good luck.

BenQ 8700 Won't Power On

As far as the projector goes, the ac power supply is fused with probably no more than a 7 amp fuse, that would blow before your breaker would if the problem were in the projector. The only thing that could case the breaker to trip would be a defective AC outlet socket or your cord for the projector is bad. I have seen cases where cat's have chewed though the cord and shorted it out and triped a breaker, outside of that if the projector is bad now then your thought of sending to the manufacturer is the best one.

No Picture

Ok. It still might be the bulb, if not make sure it is plugged in to a working outlet. Also, if that doesn't work unplug, wait 1 hour, push the power button (with it unplugged) then plug it back in. If nothing fixes your problem, it is the power supply.

On screen resolution issues

Bought a new XGA projector.../

It appears from researching that the native res for the Benq is too low 800x600 so I will never get a good picture even though most of the images I install are at least 10meg originals. Also the new projector will work in a bright room the Benq will not.

I just checked the specs on your Benq PB 6110, which has a native resolution of 800X600 and will simulate 1280X1024. When you connect it to your computer, the computer goes to 800X600, right? That is the resolution of the BenQ. How high a resolution do you want? THe highest I have seen in projectors is 1024X760, which is not that much higher. Projectors seem to lag behind monitors and Plasma/LCD/LED TVs for resolution. They must have a very small market share therefore low developement.

No power

You could have a bad high voltage transformer or problem with the power supply. If the set is over 6 years old, It would probably be better to replace it.
