Our 3rd bulb in 3 years just went out on our 65-731. I'm now looking at replacing the entire thing since I'm REALLY sick of replacing bulbs. I didn't buy the extended warranty at the time because a) I figured Mitsu could make a quality product and b) I figured I could get 2-3 years out of one bulb and 2 bulbs in (5-6 years) I'd be looking at replacing the entire thing anyway. Let that be a lesson to anyone buying a new Mitsubishi, BUY THE WARRANTY or you will regret it.

1. Those lamps are not made by Mits',
2. Lamps can go at any time,
3. The number of years doesn't mean much. How many hours for each replacement?
4. Lamp life is dependent hours and the number of on/off cycles. Dust build up and where the set is used enters in to the equation also. Many EWs' don't cover consumables.

These sets are not without their faults, but if that is the only issue you had to deal with, I would think twice about selling it.

I wanted to add that the number 1 cause of bulb failure is the on and off cycles.

But, that isn't reason to leave anything on 24/7.
post #9126 of 9409
Yeah I replaced the latest lamp today and in the box was instructions to cut out one of the screens on the lamp housing so the lamp can better cool. Hopefully that helps. The lamps are not getting very many hours on them. I can run and check but I know the first one blew with 3858 hours. I'd bet the next one didn't even last 2k. This latest one lasted less than that as I just put it in August. Its in a pretty open area, the only wall or enclosure is behind it. I dunno, I think we're gonna try limping along with the new bulb and hoping for the best again.

Silly questions... did you have a lot of dust buildup on the last lamp you replaced?

Did you get any liquid on the bulb when you replaced it?

Did you ever clean the lens in your light engine?

1) There was some dust buildup, I wouldn't say it was a lot.
2) I didn't get any liquid on the lamp
3) No, I wouldn't know where to begin on cleaning a lens on a light engine. I was hesitant enough to replace the first lamp. I did pull off the back cover of the TV this time and used some compressed air to get rid of some of the dust buildup inside.

Anyone else having the handshake issue with their PS3? I currently have an HDMI cable directly from the PS3 to the 65831 and movies will just cut out at any time.
I upgraded the firmware on the PS3 but still no luck.
Anybody else having this issue? Solution maybe?
Firmware upgrade on the TV? How would I go about doing that?
Thanks!
post #9131 of 9409
I never get a drop out with my ps3 I have that going from a denon 3808.
I do get many drops from my moto dvr through the denon.
post #9132 of 9409
I had very bad handshake issues with a Samsung BDP-1500 that I was not able to resolve. One of the initial recommendations is to update the firmware (not sure if you can even update PS3 firmware). My issue was never resolved and it was only a problem when routing it through my Denon 308 as well. Another thing to try is replacing the HDMI cable. If it is not sending a good signal it can have that issue.

I was told to unplug my reciever, plug it in let it start up, then turn on the source (PS3) you might give that a try too.
post #9133 of 9409
On a separate note. Does anyone now how to reset the service menu settings? I have the WD-65735.

You defnitely can and should update the firmware of both your Samsung BD-P1500 and your PS3.

This isn't a recent discovery, but with the advent of SDV (also known as 'musical channels') on many CATV systems, it's become a real problem. It gets to a point the digital tuners memory gets wiped out after you manually delete hundreds of encrypted sub channels over a period of time. Trying to directly access any of those wiped out 'in the clear' digital channels will fail. The only solution is a full rescan. This is due to the set adding channels on it's own (only digital sub channels). Has anyone found a solution for this? I assume it is due to TVGOS causing the set to scan all available channels (for some unknown reason) even when a host is acquired and active.

In case you don't know what SDV is;

Couple of contradictions in your post. First of all SDV is Switched Digital Video and the music channels are usually all (70+) sub-channels of one non-SDV channel (frequency). i.e. channels 102.101 - 102.171

Second, encrypted sub channels and in the clear channels are two different things. I would venture to guess (since you're keeping your Mits updated to the latest F/W available) it's the Mits set and TVGOS causing your problems.

For my setup with Comcast Digital Cable, the Music Channels are all sub-channels of a single encrypted digital channel and can not be tuned as Clear-QAM. You need a STB or CableCard.

Where are you "manually deleting hundreds of encrypted sub channels"? Most likely in the TVGOS channel editor.

My Mits did add channels on it's own (to the Mits channel memory and the TVGOS channel lineup) as TVGOS did it's scanning. I posted about that quite awhile back.

He doesn't have have the BDP-1500, I do and was trying to advise him on my experience.

Thanks

I know what SDV is and there is no contradiction or error. I said "musical" not "music". Musical channels as in musical chairs, the ones that they keep changing around.

Not really, since they are all digital sub channels and each one occupies space has a ID. It's the encrypted SDV channels that are the problem as stated.

I'm more than aware of this.

The channels that are being added are in the sets tuner memory. This has nothing to do with TVGOS. There is no change there. The deletion is under 'channels' in the TVs' menu.

But, that is only during the initial phase where the system is acquiring data. After the host channel is ID'ed, there shouldn't be any additional scanning since it knows what/where the host is unless the data stream has stopped.
BUT, the set still seems to 'scan' even when the above conditions have been met. Many times, it stops on cable 12 which is my other local 'host' even though cable 3 has been flagged as the 'good host.

After the 1st scan (other than the music channels), there were around 70 'encripted' channels that had to be deleted. The next morning, 55 more were added and had to be deleted. The next day there were 180 more. That evening an additional 70 showed. All of these are between physical channel 83 and 90, apparently the ones they use for SDV.

Both mirrors and the "output" lens from the light engine are quite dirty in my set. I realize the the mirrors are "front surface" and must be treated with care, so here is my question:

Does anyone know for certain whether or not these mirrors are of the conventional sort and are thefore coated with a micro-layer of quartz, or is the surface actually bare metal?

I suspect that since service personnel will clean these for a fee that they are most likely coated, but I would really like to know for sure.

Sorry, didn't catch the connection between musical and musical chairs. I'm not sure what firmware you've updated your set to, but I'm still at 8.03, have TVGOS disabled and my set does not add channels on it's own. It's either TVGOS doing it (my guess) or you have installed newer firmware that causes the set to do it. My set did the same thing when TVGOS was enabled. It would add the on-demand and pay per view channels, like the one a neighbor paid for and was watching. I could tune them in between 80 & 90 when the neighbor was watching and I could see it being paused and fast-forwarded. When the neighbor was done watching, I could tune to that channel again and there would be no signal. Of course, that was before I put a cablecard in the Mits. After installing the cablecard it stopped happening since the cablecard didn't allow tuning them in. Once I got the TiVo, I removed the cablecard from the Mits and disabled TVGOS on it.

V8.04 is the latest version. It addresses something other than TVGOS (going from .03 to .04) so there was no difference. That is what they sent me the 2nd time. They still haven't corrected the install instructions with those two errors.

Are you in Fast on or Low Pwr. mode?
It sounds as your MSO is using SDV which is the other part of the problem as it is here.

The fact you aren't using TVGOS probably is the reason as I'm reasonable sure that is the culprit though my Sony DVR (TVGOS is the core of the device) doesn't do this. It also seems to ignore 99% of the encrypted channels which might be the reason no additional channels are seen.

BTW, when I called Mits, I got the usual "This is the first time we have heard of this" reply.
If that was the case then that would mean no one uses TVGOS, or has SDV on their cable TV provider and/or uses Low Power mode (that shuts down the tuner section among others).

I'm still using Fast on, although I don't have to since I'm not using a cablecard or TVGOS on the set.

My MSO (Comcast), has NOT rolled out SDV here yet. If they did, I would know about it and get an adapter for my TiVo.
post #9143 of 9409
It only takes 50 seconds longer in the low power mode to boot, but uses .3 amp (32 watts) less power! There isn't any good reason to use the power hog mode.

I just got a Bluray player.
Since the 65732 doesn't accept 1080p input (from what I read on these forums), should I set the player output to 1080i?
Will it matter?
Should it matter?
post #9145 of 9409
It should accept 1080p from the HDMI input just fine.

The wd-xx732 is a 1080p television. You should have to set anything on the TV other than your color prefrences. Just make sure your Blu-rays output is at 1080P and push play.
post #9147 of 9409
Thanks for the replies.
Followup question.
If the TV can only accept up to 1080i, isn't it stressing the BR processor needlessly to output at 1080p instead of 1080i since the TV will upconvert it from there anyway?
post #9148 of 9409
It is not stressing anything, it is made to output at 1080p and again your TV accepts 1080p through HDMI (not component though). I have the 57731, model before yours, and I have my PS3, 360, and computer all feeding 1080p to it just fine.
post #9149 of 9409
From what I've read, the 65732 only accepts up to 1080i, not 1080p.
I'll try to double-check that...
post #9150 of 9409
Have you tried it yet? I have a friend with the same TV you have and they never mentioned this problem...
