I have hp 2009f monitor. It doesn't show any display. When I switch on I can see the power on light but it's dim. Nothing happens if I press on button. Can you help me?

I just repaired my own HP 2509m monitor thanks to your article. It had the exact same problem. I wonder if this is a design flaw or bad soldering? Surfing the web, I could see many people having that same flickering problem. Anyway, your help is much appreciated.

Hello
I read your article and I have the same monitor that recently started flickering.

Can you email me back if I have a few questions.
Thanks.

Hi:
My monitor would flicker and then shutdown after 2 seconds. Lifting R29 to change the current level into the ISEN pin of the INL816GN IC allowed the display to stay on. This caused me to replace both T1 & T2. After doing so and reconnecting R29 the monitor was working again.

Thanks for all your repair tips.

About those disposable nappies Anthony. I once saw on TV that those are very Fire resistant. See for instance: http://www.wsj.com/articles/SB105632614488443300
Which is probably the reason they last as long before they dissolve.

Indeed Albert...mankind does tend to not treat the earth very well at times and hopefully we can all really minimise the impact we have on our precious environment ! I for one am shocked that things like disposable nappies are sold like so many other throw away items and these take over a hundred years to break down !
Oh well, at least you and the other highly skilled repair technicians on Mr Jestine Yong's website do their their best in saving many electronic devices from the landfill ! Keep up the good work Albert !
Kind Regards
