What is the reason for my E701i-A3 failure? All boards were replaced, worked for a minute, and then had the same "fade to black" failure as the first time.


Your back light controller board or the ballasts for them may be bad if they weren't incorporated into the power supply board.

Intermitantly working v2 rangefinder


Had the same problem with my first Bushnell V2 (Slope). Worked intermittently and sometimes just quit altogether. Finally had to send it back to them. They sent it back and said nothing was wrong with it. I called them and told them they were wrong and I was sending it back and they should take more time in testing it. This time they acknowledged problem, said it was fixed and sent it back to me. I wound up getting a real good deal on the V2 without the slope calculator (necessary if you want to use it in championships). Used this one for some time with no problem, but now it just went dead again. Battery tests well into green area on meter, but I'm going to try a brand new one and see what happens. From all the things I've read about the V2 and battery life, it looks like you might need pretty fresh batteries to keep it going.

This could be a flow problem and you will need to check your pump baskets for junk and make sure your filter is clean. Also you can check your flow switch to be sure it is working.

Suddenly went blank while in use no power lighttotally dead


Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed monitors to get some ideas what to look for: http://s807.photobucket.com/home/budm/allalbums

Tv goes blank while viewing


It seems that your unit has some sort of PSU fault, or a problem that is shutting down the Power Supply Unit, PSU. This happens so that no further damage, and possible fire will occur.

You need to take the unit to a reputable service centre/man and ask for a firm "Quote" for the work to be done. It is that re-starting that gives it away, this is a typical switchmode Power Supply problem.

Optoma EP Portable Projector - No Power


if the lamp asssembly isnt screwed in tight the unit will not power on. i did have a faulty lamp once, try fitting the old one back to check first. if not the power supply is faulty on the main board or a short in the supply to the lamp can cause this fault.

Black Screen

Disply goes blank


The problem is most likely a burnt, loose, or cold solder connection on the control board. Most likely at the low-voltage transformer that supplies power the board itself. Carefully resoldering any suspect connections in this area should solve the problem. Be careful not to get too much solder on the connections that could short one to another.
