wd-65738 tv screen goes black for a second or two several times a day. It started a month after I got it. At first, it happened a couple times a day, now several times. Does anyone else have the same problem? Should I be concerned? Only Dish HD Dvr is connected. The tv is 9 months old and I brought it brand new. Not refurbished or open box. Thanks!

Mine only does that when first turned on and I'm attributing it to finding the video source so I think my situation is different.

This happens whether I stay on one channel all day or switched channels.

I'm not to sure on the scope of this issue or how much of a problem it is to correct, but what you describe is not how my 65738 behaves. I'd call mits and report the issue. get a tech to look at it under warranty.

Seems to be a handshaking issue. Start by trying a different HDMI cable.

I wanted to jump in here.
I bought the WD-73740 back in Feb of this year 2012. The very bad weather we had just last week (4/14/12) caused the tv lamp to blow. The tv was actually off. When we came home, the tv was "on" but with only audio, and no picture. We had a lot of lightening, A LOT. So I suspect lightening spikes caused the tv to turn on (some how), then also destroyed the lamp. Oh... and BTW... the tv WAS plugged into a 20 minute battery backup with surge protector. So if people feel they are save by doing that, think again. Not so true! Battery backup will not necessarily save your tv, or the lamp from blowing in heavy lightening and power spikes.

So my dilemma is.... just how can one protect these tv's in bad weather or during power spikes? The only sure way would be to unplug the tv from the power source. But that is hard to do when storms pop up, or you are away, or in the middle of the night.

I tried the suggestion on the mits web, to pull out the lamp then slide it back in. Also tried the suggested reset procedure. That did not work either.

So on the following monday I called Mits support and they rushed out a warranty replacement lamp. Got it wednesday. Replaced the dead lamp, and the tv fired up right away, picture and all.

But again I ask.... Just how can owners of DLP tv's protect the tv from power surges/spikes/lightening/etc ?????

I don't think it is possible to reliably protect these sets from power issues or terror from bad storms. I guess as long as you are under warranty, they will rush out a new lamp. After that, the only option is to always have on spare lamp nearby ready to go. And if you use up that spare lamp, re order another spare ASAP right away so as to keep a spare on hand.

Though it may still not be enough, make sure that EVERYTHING that's connected to the TV goes through a surge protector. This includes your network connection, antenna / cable TV connection, and any other components that are connected to any of the inputs on the TV.

If that still isn't enough, then the only sure way to protect the TV (and your other equipment) is to unplug everything - this includes unplugging antenna / cable TV connections, etc. - anything that is a point of entry to your house. But as you say, this just isn't practical especially when a storm pops up when you aren't around to unplug everything.

Nothing will protect from direct lightning hits on the power line. Surges, spikes, or brown-outs, yes. Lightning coming straight down the wire, forget it. Years ago door-to-door scammers used to convince homeowners they could protect themselves with lightning rods installed on the roof. A properly grounded home electrical system already serves that purpose, but it's still no insurance against full-on hits. If there was such a thing electrical companies would never be replacing transformers in the wake of big storms.

So we have warranties to protect ourselves against such anomalies.

Warranties DO NOT COVER lighting damage. Your Home Owner's Insurance does. Read your warranties.

I had a most unusual situation that caused my 60738 to shut off a month after I bought it. I was playing a show previously recorded on my Tivo when the MITS power shut down just as an explosion took place in the video. I turned it back on and rewound the program. When it got to the same point as last time, the MITS shut off again. I did it again with the sound muted and got the same results. A flash of insight caused me to cover the TVs IR remote receiver and the TV did not shut down. The flash of light from the video was activating the remote control receiver. I saved the Tivo recording so I could recreate the problem again for a friend who was a tech. He confirmed that was indeed the problem. He said that he once saw the same problem where a particular light frequency kept turning off an A/V receiver.

I thought of this when it was mentioned to have happened in a lightning storm.

As for protecting your TV or other components from a lightning strike, I believe that the only protection is to unplug everything. Back in the 70's, my cousin's house took a direct hit of lightning. Her TV was turned off but the current went through either the power cord or the antenna wire and fried the TV. From the looks of the damage, she was lucky it didn't cause a fire. I think that the only absolute protection against damage from lightning is a good homeowner's or renter's insurance policy.

As far as cost/performance goes, it's hard to beat a Mitsu DLP. Sure, the black level and all that, but check out the price of a flat screen that's bigger than 65". DLP's can be a little quirky at times(lamps, geometry, etc.), but nothing to get in a twist over. I'm sure you'd be happy w/ one.

Has anyone found any deals out there on replacement bulbs?

Reason I ask. Was watching my 82" the other night and all of a sudden the picture started strobing rapidly. Seemed that it was going from color to black and white very fast. Can't really tell since it was switching so fast. Shut the set off and it was back to normal. Very next day I was streaming Pandora through my DVD player and I notice that the strobing came back on the TV, but this time the picture was pulsing in response to the strong bass notes coming from my full range PSB Stratus Gold speakers. Paused the music and strobing stopped. So I'm thinking that the bulb is on it's last leg and is flickering?

If it's not the bulb my set has serious issues! I hope it's not the light engine? It has not occured in the last 5 days. I'm out of warranty as of last October so I figured I could change the bulb and see what happens?

Any other advice?

I would only recommend an OEM lamp.

As for strobing to black and white, that doesn't seem like a lamp issue, as the lamp only provides white light. If it was caused by the lamp, it would change intensity maybe, but not color.

Strobing to the music may be evidence of a loose connection somewhere. Re-seat your HDMI cables. If that doesn't work, call Mitsubishi service, and at least report it.

I agree. It wouldn't be a bad lamp causing your problems. Checking for a loose connection or cable is a good course of action. If that doesn't solve the problem you would have to go for a warranty service call.
I wouldn't tell them that it goes along with your speakers. Just say that the problem is frequent and random.
Sort of like telling the doctor "It hurts when I raise my arm" and he answers "don't raise your arm and it won't hurt"

Then when you get a tech over, recreate the problem.

I've had too many run ins with phone support people that I now explain a problem in a way that they won't treat me like I'm an idiot who wouldn't know which button to press to turn the TV on.

As for buying lamps. I would recommend that you should have a new spare so that when the current one starts to dim, you won't have to be without the TV for the 10 days or more that it would take to get a new one.
Over the past 2 years, I have bought 3 new lamps with housings. Each time from a different company other that OEM (Mitsubishi) Mistubishi charges $99 plus shipping. I bought each of mine when I spotted cheap deals. When each lamp arrived, I popped it in the set and ran it for a couple of days to make sure it was good and each time they proved to be good. The original factory lamp lasted about 4200 hours. I could probably have kept using it at diminished brightness for a number of hours, but that would suck. The lamp in there right now cost about $60 and has been lit for about 5400 and going strong (knock on wood). But if it goes, I have a good tested ( and less expensive) spare to replace it with right away.

The prices for lamps with the housing jumps up and down almost weekly. The last place I got one from was for $65. Right now its at $72 +free shipping. Do a search on Amazon and Google for "DLP Lamp 925B441001" or Mitsubishi part# 915P106A10. (I'm assuming you own a WD-82738) and you'll find prices ranging from $59.95 to $145. If it was me, I would make sure they're a legit company either listed on Amazon or eBay or if not there see that they have an address and phone number.

Mine has roughly 3000hrs on it(standard not bright). Do you recommend a spare so soon? Also, when you replace the lamp, don't you just have to screw in a new one like a light bulb?
