Asus vw246h 2 secs to black help please

[MERCSTAR187]

hello all
right i have an asus vw246h that started to flicker a little bit hardly noticable this lasted for a month or so and then came the 2 sec to black problem. in all my haste i changed all of the caps except the big 1 on the power/inverter board which made no difference still has 2 second to black . so back to bad caps for more reading and found this lamp testing with out a spare lamp

b) Alternatively, if you do not have a spare CCFL, then try this test.

a) TURN POWER OFF and unplug the monitor and wait 1 minute
b) disconnect all CCFLs expect #1
c) plug in monitor and turn monitor on - note if "2 seconds to black" occurs
d) TURN POWER OFF and unplug the monitor and wait 1 minute
e) disconnect all CCFLs expect #2
f) plug in monitor and turn monitor on - note if "2 seconds to black" occurs
g) TURN POWER OFF and unplug the monitor and wait 1 minute
h) disconnect all CCFLs expect #3
i) plug in monitor and turn monitor on - note if "2 seconds to black" occurs
j) TURN POWER OFF and unplug the monitor and wait 1 minute
k) disconnect all CCFLs expect #4
l) plug in monitor and turn monitor on - note if "2 seconds to black" occurs

after trying this i found that #1 does not light up at all but the rest do the 2 sec to black so i pluged #2 in to socket #1 and it does the 2 sec to black. so does this mean i am just in need of 1 new ccfl as i read somewhere that all lamps need to function for them to stay on. i have no pictures at the moment camera on charge and monitor back together will get some ready if more investigation needed any help at all will be much appreciated

many thanks gareth

[QUOTE=jetadm123;378474]True that all lamps needs to be good in order for them to all stay on. It's pretty much an all or nothing type of setup. That's where a spare lamp comes in handy. Since you don't have a spare, what you did is also acceptable. I would check the wiring to ccfl #1 as it could be broken. And worst case is the ccfl is broken or burned out. Perhaps someone in the UK can recommend a source for replacements. And there's always eBay.

Re: Asus vw246h 2 secs to black help please

also would it be a good idea to replace them all as im in there anyway ?

Re: Asus vw246h 2 secs to black help please

Sourcing a new one usually involves measuring the length of the old ccfl. Good info for this procedure can be found at ccflwarehouse.com. Diameter can also be a factor. It also wouldn't hurt to find out the cost to ship to the UK from the USA. As for replacing them all, find out the cost of one first as it may not be worth it to replace them all.
