Picture flashes on and off

check the capacitors first, they are usualy the weak link.

If you removed power by turning off power itself to the set instead of turning it off by turning the set itself off---that is not a good thing to do.

When power is restored a surge can and likely hit the power supply in your set---time for a tech or shop to open it---I suspect they will find the standby or main power supply is damaged or now bad.

Check the lamp.

This problems the FBT-the Flyback Transformer have cold solders.Must resolders the FBT.The right side wall of the FBT-the "H" horizontal transistor,must be also resolder too.

First I'd try turning the flash off, a manual option on nearly all camera's. Take a couple of photo's without flash, and turn the camera off and on a couple of times then turn the flash back on to auto.

If that doesn't resolve the problem, I suggest going to the HP website, follow links to support and/or downloads and see if there's a firmware upgrade for your camera.

my 2002 sony wide screen projection tv has menu and pictures when turned on first thing in the morning?

Call Sharp for warrenty repair.This problem very common in Sharp tv.Picture will come on turn power on/off button few times will work.But still under Wareenty call to Sharp to replaced the main Tuner Signal board.

replace the monitor. try another monitor. if another monitor is OK then it's time to get a new video card.
