Having problems with your Dell E173FP 17" LCD Monitor ?

Dell E173FP power led orange/flashing failure returns

\015 The power led was orange/flashing with nothing showing on the screen. Replacing the (4) 2sc5707s fixed the problem for about a month. After that, the power led started flashing again, so this time I replaced the (4) 2sc5707's and the (2)FU9024N's. This time it worked for a couple of weeks before it went out again.Is there another component that could be causing this failure?Maybe the 0.22uF caps?Thanks.\015

Answers :

First, you can get the service manual here: http://elektrotanya.com/
\015\012If the transistors failed again, yes the 0.22uf (part of tuned circuits for the inverter transformer oscillator circuits) changed value, the frequency will be off and causes over heat on the transistors due to too much current draw, You can also have bad inverter transformer, you can check the DC Ohm value but if it has one short turn, it will not show up on DC Ohm test, you have to use ringer testing (I use SENCORE LC75).
