I have been trouble shooting this non working monitor. The problem is that the backlight won't fire, only the blue flashing power light. My question is would it be possible for one of the 6 cfl's being bad and causing this problem? They won't light up at all.

Re: samsung 205bw
In general a bad CCFL won't prevent the backlight from starting. I'm curious about the "blue flashing power light". How fast is it flashing? Does it ever go on steadily?Originally posted by jtoff7273

Re: samsung 205bw
Thanks for the quick reply. I didn't think it would keep it from lighting but wasn't really sure. The blue power light blinks at a steady rate and never turns solid.Comment

Re: samsung 205bw
That indicates a problem with either the power supply or a corrupted eeprom. If the caps look good, google monitor reset.Originally posted by jtoff7273

Re: samsung 205bw
The caps look good. I pulled it out tonight to have a fresh look at it and measured the voltage at the 2 caps before before the inverter and it had some pretty wild voltage swings like 5 to 15 volts. Ideas?Comment

That sounds like a SMPS that is having startup problems.Originally posted by jtoff7273
Read this faq, then attach pictures (top and bottom) of the power supply / inverter board.

Have a Samsung UE43KU6400U that will not turn on, just continuous flashing red standby light.
Power button does nothing
Have unplugged the mainboard, and backlights illuminate.
Have tried removing panel ribbon cables one at a time, and that makes no change.
With mainboard unplugged, all voltages from powerboard seem ok, but with mainboard connected, they never quite reach full voltage, and drop and raise in a constant loop (in time with click noise from mainboard.
Using backlight tester, I get 63.6v on both sides, so seems like no bulbs... -
Hi
I aquired a Samsung UE46EH5000 from a lady that said it was turning on and off so she just purchased a new one.
On plugging into the mains and turning on i get a solid red light.
On using the on/off button or remote i just get a flashing red light in a pattern of flash/flash gap flash/flash gap flash/flash etc.
Opened it up and disconnected the main board from the power board by removing the connecting ribbon cable with the hope of getting either a 'no backlight' or a 'working backlight' but got neither,i just got a blinking backlight that turned on and off randomly... -
Hello everyone.
This is my development machine. I've been using it since two years and half without any problem except sometimes it wouldn't wake up from sleep.
Lately the issue became more frequent and powering it up would take few seconds to show the POST screen.
Then the computer refuses to power on at all. Now only the caps lock button flashes 7 times then stops. The charging light is always on whenever a power source is connected (battery or charger).
I tried long pressing on the power button, after several seconds it would go off then when the button is released...
