I have a Westinghouse L2046NV Monitor and it does not come on. The monitor has gotten worse over time. I have removed the power board and found the six capacitors to the right are all bulging and 3 of them...

You may want to get the capacitor kit, but you need to get the board number used in your monitor version.
Eample of the kit:

I will not use RadioShack caps, since they are not low ESR type which is required for switching power supply, they will not last if you use generic electrolytic caps.

You should remove one cap at a time so you can see what the value is for each cap.

Capacitors kit: he can make you a set of caps for you.

Or just make sure to use caps with low ESR, 105c, high ripple current, long life rating such as PANASONIC FM or FC series.

Turned on the monitor this morning and it would not come on. Several tries, no luck. The 'on' light flashes green/red together. Bought 12/07. Can you help? (I've borrowed a friend's monitor to contact...

If you are to DIY repair, please read below so you will at least know what to look for.
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed monitors to get some ideas what to look for:

How do I reset my Westinghouse L2046NV monitor -- this monitor will turn on and light up and the picture will come on but then go off after 1 or 2 seconds -- any ideas ?

Hello, reseting your monitor will not solve the problem, what you need to do is replace the inverter board, if you would like to know price and availability for this model please send a request to, they will let you know if they have the board, how mutch it is, and they will also troubleshoot with you over the phone at no charge to make sure that is what you need.

Open up the unit. You should replace the damaged/bulged caps on it. You should also check the two MOSFETs before the transformers on the inverter section. If that does not do it, there's one SMD fuse beneath the card that normally blows when the MOSFETS fail. You should either replace it r bridge it with solder.
