Have you checked the power output from the power board? Is it constant and steady? Try reflowing all the joints if you haven't already. Especially transformer and coil joints. Maybe a bad logic board? Do you have spares to try? Does it do this with everything disconnected from the pwr board (switch, logic, inverter)?

Is is a DC or and AC output supply?
If is it an AC output supply tyhebm in the back of the HP had an AC to DC converted that is realy a diode bridge and should contain a fuse in the circuit somewhere on that board

Any malfunction associated with a flashing light usually indicates a circuit problem or defective component. Unfortunately, the days of taking off the back cover of your TV and replacing a defective tube or fuse are long gone. Proper servicing will require troubleshooting procedures that can only be performed by a qualified electronic repair facility or professional television repair person. Ask for an estimate and a realistic appraisal of whether the set can be adequately fixed. Depending on the age and condition of your TV it may not be cost effective to repair.

You need to open it up and inspect the componente inside, look at the fuse and the transistors in the inverter circuits first, also look for sign of over heating on the board, see pictures here for the guide: http://s807.photobucket.com/home/budm/allalbums

hi, extremely common problem for dell 17 in monitors. the capacitors and transistors on the power board internally have gone bad. to get repaired, it may cost 40-50 at a shop. i have repaired these in the past and they always come out well for at least 3 more years. may want to find another monitor though. if you would like steps on how to repair, let me know and i will find my old repair threads to give to you.
