Having problems with your HP Computer Monitors ?

Hi my hp1940 monitor is going off and on it looks like the power is flashing. i understand that this is a common problem with tft screens and i did read about it people are talking about ccfl ? or so can you explain to me what thet is ?


Answers :

At my HP1940 are Q805, Q809 and PF701 defect!
Mostly this is a lamps ignition failure.Check on the mainboard near the trafo`s trazistors Q805,Q808.809 and Q812,815,816 and replace the bad one.
\015\012If the test is positive(all tranzistors are good),you need to obtain somehow one good lamps block or one lamp and test with it four lamps on CN801-804-one of them must be dead.Next move is the art of accuraccy...:)
