Question about ViewSonic OptiQuest Monitor

1 Answer

Turns off and then turns back on again on loop

The Flat panel of the screen is good, when you turn on the screen it flickers on for a second (just long enough to read RGB in the corner) and then the screen immediately turns off and then turns back on again on loop.
Can i fix it or is it to throw away?

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 Viewsonic monitors to get some ideas what to look for: http://s807.photobucket.com/home/budm/allalbums
Post back what you see inside so we can guide you further and it will help out other people in the future also.

Why when I turn on my Bauhn TV the screen flickers for approximately 40 seconds, then it is good. It is out of warranty. Can I personally fix the flickering? I am not financial enough buy another.


I have no idea of your technical skills but I would assume you could not disassemble it repair it and reassemble it. I would go to where you purchased it, they may be able to work something out with you.

What else should I check on my Sanyo DP42840?


This could be the tuner overheating and sending a signal from the tuner board CPU to the power board to instruct the tuner to turn off. Check that there is adequate ventilation in the TV. Try testing with a fan to see if that changes the behaviour of the loop that you get.

Sony 52xbr4 screen flickering


Fault with the main power supply regulator board. Ubnormal DC voltage output from it. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts.

It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and precious time.
