I posted my latest settings a few pages back. Since mine should be coming with the latest firmware I will have to work at them again.

Latest update is they replaced the power supply (again) and are now waiting for a new lamp. I am waiting for a call from the technician so I can tell him that is exactly what they did the last time it was there. And since I put hours on very quickly I will tell him to expect it back late next month! It has to be something else. I hope he "gets" it when he calls me...

Sure is.

You really might want to consider that the sound you are hearing is hum caused by DC current on your AC line. This isn't necessarily a problem in your house itself. These design of these power supplies might make them sensitive to this. It can be fixed. See here.

It seems pretty textbook from what you are describing.

So why would it suddenly appear with this particular PJ. I have never had an issue with my previous 200, vw60, vw100 and the recent FPJ1/RS2 and RS20. And never with my Optoma DLPs and whatever brand I had briefly before them. Could it suddenly just show up? Seriously.

Another thing. Would it be a consistent noise if it was electrical related or would it gradually get worse (louder) which is what happened. The last time I had it on it was a very high pitched noise and not the cricket type. You could hear it before you got down the steps...

Hopefully I can speak to the "head" technician sometime today...
post #1508 of 2113
There could be several explanations that are consistent with the cause of the noise being mechanical hum and it only appearing on your latest 200 and not your earlier PJs. First is that your power company is doing something different and whatever this is has introduced DC current on the AC line. Another explanation is that Sony is now using new power supplies and these are more prone to hum. Another explanation is that the particular PSU that is in your projector may have had less varnish or super glue applied (or maybe it was improperly applied) to the laminations in the PSU.

The sound would likely vary. From the link:

If you suffer from this noise problem, you've probably also noticed that it's intensity varies depending on the time of day, sometimes even the time of month. The reason it varies is due, in large part, to the quality of the AC line voltage and how much DC is on it.


I hope that the new PSU fixes the issue for you. If not, try the Humbuster product. It is a risk-free trial.

I have no connection at all to the company and have never even used any of their products. I have been told by others who do know that they very well.

I appreciate it Lawguy. When I get back the 200 I will try one if it starts up again. And since I have my outlet in a nice "box" in the ceiling I could easily connect it in there (where I have the Monster AV Surge) and hear if that does the trick. I am never afraid to try "new" things.

Hopefully you won't need it.

Good luck!

Joerod. Your problem is not caused by any DC component of you power. It is not a ground loop problem which BTW has nothing to do with DC either. Your monster or other pl conditioner probably won`t help your problem either any more than a cheap spike AC overvoltage protector.. With ground loops you would see hum bars traveling on the screen.


The Sony operates over a switch mode power supply (SWPS). No need for big transformers which can hum. Your problem isn`t hum. Its failing SMPS, The starter is starting to fail. You start to get multiple pings. Not right and Sony replaces the whole thing. Why does it fail? I don`t know. You might ask the Sony tech what might of happened to cause the failure. He won`t say DC on the line. He won`t say ground loops or noise. About the only thing that might cause it was high voltage spikes on the AC line. If that`s the case, an overvoltage protector might help. Every powe conditioner has one, they cost say 25 cents. They just shoot the overvoltage to ground before it starts to fry your powerr supply.
post #1512 of 2113
All PSUs have transformers. All transformers can hum, they don't have to be big, whatever big means.
post #1513 of 2113
Lawguy. DC on the line can cause certain noise problems as described by PM, the P in PS Audio. DC causes mechanical hum. Most hum problems are cause by AC ground loops.

Joerod is describing problems not related to hum. He is singing byt not humming. Whoops, his PJ is pinging, not singing. It is a failing start circuitry in the SWPS supply. this has been a history with the Sony`s. Usually the problem isn`t severe, the thing keeps starting, but near the end of the warranty period it should be replaced to avoid a high cost repair later plus you can get other wear issues addressed such as replacement of a nosier than it should be fan.
post #1514 of 2113
Sounds like he is describing mechanical hum. This is the insect-like noise (they are calling it crickets in this thread) that is described in the PS audio link.

I never thought it was a ground loop.
post #1515 of 2113
Of course, the chirping is coming from inside the PJ and not from a speaker. Not a ground loop. Some thing is sounding like Jiminy Chirp. But I doubt that sound would be made by DC hitting a transformer in the SMPS. If DC line component were going to be a problem, the solution involves adding some diodes or other minor components to the circuit. BUT The SMPS already would them assuming it is properly designed. Siny engineering is not dumb and they have had numerous failures with the SMPS and lamp. If a running mod like adding the diodes we forget whoops, they would have a running mod. Its something else. Nothing that adding diodes would fix,
post #1516 of 2113
Yes, adding diodes to the line in series is exactly the fix for mechanical hum. This is what the Humbuster does.

I just got off the phone with Jose' the Chief Technician. He plans to "comb" over the PJ and look for something else that also might be causing the issue. He said their first course of action is power supply and lamp. He will look at start up chain and go from there. He also said when they send it back if it does start up again they would just replace it with a new VW200. This will be the third new lamp put in this one and it has only about 300 hours total time! I guess it is pretty new already... There just waiting for the new lamp to get there then they plan to test it and send it back (in the meantime they are looking it over again)...

My late Friday update... I tried to type in the work order number on their website and it didn't give any info. Said I had to call. Since Laredo was already closed I called "Prime" support. They were able to tell me they received the backordered part (the lamp) on Friday. I guess I won't know anymore until Tuesday...

Update.... The parts have been replaced (including new lamp) and they are "officially" looking to see if there is something else wrong...

The latest... They received another part to put in it today... So now they will have changed the Lamp Power Supply, put a new Lamp in it and according to what I was told today they are doing the part Mark mentioned (Starter Supply)... They said that should be done today and they will ship it back Next Day shortly... If I were a betting person I would guess Monday or at the earliest Friday it would leave Laredo... I have a busy weekend already so I can go another weekend without...

Just checked the status "for the heck of it" and it now says updating status...
post #1524 of 2113
Basically, you are getting all the wearable parts replaced except for the chips. The chips, drive circuits, optics couldn`t be causing the problem. A new one wouldn`t be much different than your repaired one. It might be a design issue with something weird going on at your house. I dunno.

I doubt if it is something at my house since out of all of the PJs I have had up there (quite a bit) this is the only one ever to have a problem. And since my fist VW200 was flawless and the fact that this exact VW200 was in Laredo (for the same issue) last August that is proof enough that it is the PJ. I agree, no point in getting a brand new one now. This repaired one should be like getting a brand new one that has been tested. Plus a new Lamp will also make it feel like a new one...
post #1526 of 2113
Isn't there a lemon law for projectors, too? I've always had good fortune with Sony so I'm a bit surprised. You'd figure that with the amount of issues with this particular VW200 it might be time to retire it and send you out a new one.

Any word yet on a new Sony high end projector? That "VW90" or something along those lines?

How does "A Bug's Life" look on this projector? I have an older Yamaha 720p that will be replaced by the new Sony this fall (I have decided to skip over the VW200 for the next big thing from Sony...nothing against the 200 but I have decide to wait for higher tech vs. the Xenon bulb) and it looks awesome on 720p...I can't even imagine what a 1080p projector can do with this remarkable disc.

I just picked up A Bug's Life and it looked great on my new Panny 1080p 50" plasma. According to Sony if it has to go back to Laredo one more time they will just send a new one. They have a 3 strikes rule. I don't think it is a large number of 200s that have had this issue. I know my very first never made a sound. I know others who have them and have never had a single issue. The VW90 without the Xenon will still not be able to compete with the 200 in terms of color. If it had 240hz that would be something to think about it. I don't think there are any plans for a 300 for a pretty long time. Mark would be our "go to guy" for the latest info n the Sony PJs coming....
post #1528 of 2113
So the Xenon bulb is the deal breaker for you. Is it that good? I have not seen the VW200 in action but I have seen a lot of the newer technologically advanced projectors and they looked pretty darn good to me. I would think if a new Sony projector emerged this fall it would better than the 200 across the board....save for the bulb. At least that's what I'm hoping for :-)
post #1529 of 2113

It would take 240hz and much better contrast to make me give up the 200 for a VW90. The Xenon lamp is that good. If you haven't seen the 200 in action with the Xenon Lamp(beautiful/accurate colors) then don't.
post #1530 of 2113
Many of my Sony friemds are gone. May 29 was their last day. We will all be getting Sony from a distributor now. I have no new information since Cedia. The 90 willl be better in every way from the 200 except for the Xenon bulb. also the lenses will be the same. I don`t I will know anything more until Cedia in early september absent any official info from Sony perhaps very shortly before Cedia.

I think Sony just doesn`t very many people care about Xenon and the added cost of a zenon including much more expensive bulb replacement costs.
