Question about Computers & Internet
My monitor has some problems and probably something did get to hot. At first I noticed the left upper corner was darker then the rest of the screen. Later I noticed a bad smell, like a small part of a PCB was much to hot. But what ever had burned, it does not stink any more. After I turned the monitor and the computers off it made a tick-tick sound (similar to a mechanical clock) while booting. The permanent damage is a darker area on the top of the screen. It is like 1/5 of screen has only half the back light as the rest of the screen. I assume the back light is made of several pieces and to the top peace is defect. I have read the durability of the back light is a problem, HP has released a software "HP Display LiteServer" to get the most until the back light fails.
What you can do is to remove the back cover to access the inverter board. probably the cause of the smell is burned inverter board for the screen back light ( ccfl ) at the upper portion of the display.you can find the inverter board near the power supply board. usually you will replaced the inverter board since most of the part get fried as will as the pcb pattern circuit board get burnt.hope this can help good luck.

Assuming you've already checked your driver and system settings, tried a different monitor, and checked the cable and connector pins, this would almost certainly be a problem with the power or signal circuit board inside the monitor.

I have the same problem except it usually happens after Ive left my computer idle for a while... i.e . Overnight, I usually turn off the monitor and I hit the button after I come back to turn it on. I get the same flashing light for several minutes. This has been a problem for several months, but only recenly have i gotten the same error message you mentioned. Each time ive booted the computer up cold or restarted it has worked fine but this time it took longer along with displaying the message: Top Left to Right: SH770 P001 Bottom Left to Right: AU M170EN05 Anyone else who can clear this up?

Chances are that you are not hurting anything with the lower power supply. What is probably happening is most likely two fold. 1. The light bulbs in the backlight circuit may just be wearing out and need replacement, and 2. the lower current power supply may not be capable of producing al the current that the monitor needs at certain times during operation. I would suggest getting hold of the correct power supply module and see where that gets you. If you still have the red outs,replace the light bulbs in the monitor. The only other fault than that would have to be in the video controller. Hope this helps.

Press the PIP (picture in picture) button once again. It is the leftmost of the front buttons below the panel, opposite the on/off switch.
