Where are the dc filter caps located - Sylvania LC225SSX LCD TV

without schem measure the AC ripple on the DC line and see if it is unreasonable. If so start replacing filter caps. measure AC before and after - if change is large the cap is probably ok.

to locate the oil filter you will need to remove the top cover of the engine, with the cover off and you standing in front of the car look toward the right of the motor and down, to the right of the intake manifold,, you will see a cap, the filter is located inside the housing, use a socket over the hex on the top of the cap and unscrew it counterclockwise, remove the cap and the filter will be on the cap, slide filter off and then you will see an oring on the cap, remove it and install new one supplied with the filter, this filter is a cartrige type, slide new filter onto cap and installtighten cap a little not to tight,lets see if i can find a diagram to help you locate it.

It can due to unsteady DC voltages in the power supply because of the dying DC filter caps, it may get worst, I would inspect the caps first, more damages can result.

Capacitors kit: http://lcdalternatives.auctivacommerce.com/ he can make you a set of caps for you.
Or www.digikey.com just make sure to use caps with low ESR, 105c, high ripple current, long life rating such as PANASONIC FM or FC series.

Inspect the DC filter caps in the secondary DC power supply filter caps first and check the voltages.

No shorted out MOSFET, inverter transformers, surface mounted DC filter caps (this one is hard to located because they a lot of them in parallel). You may be better off getting new board.

It can be bad DC filter caps for the 16~18vdc for the backlight circuits, bad backlight circuits, bad backlights assemblies. You should inspect the inside for the bad caps with leaking/bulging top/bottom seals first, then check the DC voltage feeding the backlight circuits.

It sounds like you have bad DC filter caps in the power supply, when its cold the ESR (Equivalent Series Resistance) will go up if you have bad cap, goes down when it is warm up, I use hair dryer for locating bad caps, and small low watt soldering iron for heating up individual cap once the general area is located by hair dryer, this trick is 30 years old! You can see ESR goes down when heated if you have cap meter with ESR testing function.
If you are going to DIY and have proper tools, electronics knowledge, and know safety precaution then please read on:

Check out the DC filter caps first, see failed Viewsonic due to bad caps.

HP doesn't have a replacement power supply available, and to my knowledge there is no replacement power supply available.
The power supply itself would have to be rebuilt.

More than likely if it's the power supply, and not the fuse in the power supply area, (Behind the plate with the two Number 10 Torx screws. BE SURE, the printer is unplugged from power!), it's an Electrolytic Capacitor, or two that have gone bad.

Electrolytic Capacitors are Filters used in a power supply.
In the Input stage of the power supply, they filter the incoming AC electricity, before it reaches the rectifier.
In the Output stage of the power supply, they filter the rectified DC electricity into true DC electricity.

Look to see if you have any bulging, or leaking 'Caps'. You have to use the same voltage, but you can go slightly higher with the Microfarad's. (mf)

Example: I replaced two 16 volt, 330mf 'caps' with two 16 volt, 430mf 'caps'.
('Caps' = Electrolytic Capacitors)

More info to help identify bad 'Caps'.

On the V6, the filter is located on the bottom front of the engine on the passenger side. It is silver and looks like an oil filter cap wrench. It is not the traditional oil filter where you replace the entire unit. With this type you remove the cap, drain the oil, and replace the paper filter element and 2 gaskets.

to get the cap off use a standard 65mm-67mm filter wrench "end cap" that you stick on your 3/8" drive ratchet like this one..
