My 22w3 (bought it reconditioned) after about 10 month, now it has the 3 second and goes blank problem when I first turn it on. I took it apart and a couple of the caps were bad so I bought the kit and replaced them... still have the same problem so (the first time I've done something like this I figured I screwed it up) I bought a PS board and replaced it .. still have the problem. So in doing a little googling I found that most of the pics of the 22w3 ps bd is different than the one I have dont know that it makes a difference. The one on the left is from my monitor, any suggestion for my next step. Thanks

Re: westinghouse LCM 22w3
"2 seconds to black" can be
a) bad caps
b) bad inverter transformer
c) bad ccfl
d) bad ccfl wiring
e) bad ccfl sense circuitry
Since you bought new caps and a replacement power board, that likely eliminates a) and b).
That leaves c) d) and e). Concentrate on c) an d). See pictures at

by ttmi100xGreetings everyone,
I have a HANNSG Hi221 monitor that exhibits two seconds to black issues (backlight goes off, display is still on as confirmed by shining a flashlight on it) with some additional oddities...
The monitor failed on me with a standard "2 seconds to black" some time ago prompting me to initially replace most of the electrolytic capacitors (some of them were bulging/leaking).
Things kinda sorta worked for a night, then the problem returned along with some flickering and "buzzing" noises.
Upon closer inspection...6 Photos-

by mikey5791Hi,
This monitor previously is my main working monitor which i have been using for 8~9 years. Yesterday, when i switched on my pc from fresh to power on, the monitor is just black no display. I started dismantle to look inside the monitor power board but nothing looks suspicious or burnt. So i took my external ccfl inverter to try to power the monitor ccfl lamps which consisted of 2 lamps on upper part and 2 lamps on the lower part.
Found out the upper ccfl lamp which is supposed to connect to cn304 on the power board did not light up. Then i installed a used working...-

The price of this offer has gone up sense I bought these two boxes
I bought two boxes of these batteries but there is a catch to the these battery packs
The BMS protection board does work but it... -
by xnRSToday I bought... I mean friend of mine bought capacitors that I ordered, as the shop where i bought it is too far away from me, as he isn't understands anything in electronics, he just bought it as I ordered. At first shop on their page showed 1800uf 6.3V Sanyo caps, with generic picture and code SY-1800(which isn't correct). After little bit of search I found out that it was WG 8X20 capacitors(p.s found that out before buy). Ok, ordered, next day friend gives me package with those caps and some other caps that I ordered. But... This were NOT the Sanyo WG, these were Panasonic(Matsushita) FL...
