Official Mitsubishi WD-XX734 Owner's Thread - Page 67

post #1981 of 1996
My TV is getting fixed tomorrow. Woo hoo.
post #1982 of 1996
Mitsu sent out a repair tech who installed a new DLP chip. I agreed to pay the $225 labor, free part. This on a 73" set 2 weeks short of 4 years old.

Looks great. 8000 hours on the original bulb.

Just last post here to report on my TV.
My local authorized repair shop came to the house last Friday afternoon. Took out the LE. I asked him to vacuum it out good. He did. He took out the old DLP Chip and put in the new one. He showed me the old one. Hard to see anything on the chip. SOOO TINY. Interesting though. He put it all back together was was gone with in the the hour. He check the screen with us. NO DOTS. Were happy. For a $100 bucks. Well worth the call to MIT and the wait. Over all, took about 2-3 weeks. Thank you MIT.

the two times i got blinking green light, they fixed by replacing the main board. However, in the past, Mitsubishi DLPs have also had blinking green light due to deteriorating capacitors and could sometimes be fixed by replacing those bulging caps. See the XX525/725 thread for more on that.

I have a opportunity to buy a WD-65734 for $150. Only problem is that it has the "white dots" of a bad dlp chip. I have looked around and watched all the youtube vids and am sure I could swap out the chip and can get the new chip for another ~$150. Does this sound like a good deal or should I keep looking and scrape some more money together for a newer set?

Thanks.

Hello all. Need some help. Have a WD-65734 made in mid-2007 we bought new Christmas 2007. We have the white dots on the screen, but as of yesterday, a much bigger problem in the TV will not turn on. The TV worked fine in the morning and then when my wife got home from work she went to turn it on for the kids and it wouldn't start / turn on. She thought it was the bulb. After I got home we changed the bulb, even though I told her the bulb didn't look blown. The TV still wouldn't come on. You can hear a clicking noise, like a relay switching on & off, but theTV will not start. The TV's green power light blinks rapidly for about 30 sedconds and then the red light comes on solid. You can hear the audio but absolutely no picture. I also have another spare bulb I got when the original bulb went out & a aftermarket bulb failed right away, so it was sent back to be upgraded to an OEM bulb. In the meantime another bulb was bought a closer shop (all of the bulbs are are original Osram's). We then tried the second spare bulb & the same thing happened. I tried pushing the system reset button on the front, but now the same thing happens and instead of audio we just hear static (probably because the there is no input selected).

does it look like the bulb turns on? just no picture on the tv? it could be the ballast and not the bulb.
I have the same TV and have taken apart just about everything and have replaced just about everything.
Just looked into some of my receipts and I replaced the lamp temp sensor for a no turn on situation.

Also there is a lamp door switch that needs to be activated before the bulb can turn on(i did this with a yellow led though).

do you have a solid red Lamp or Status LED?

Thanks Nivo855. I did figure out the LED door switch last night b/c I tried to restart the TV to check the bulb without replacing the door & the yellow LED did come on. Now with the DLP bulb access door on, after I plug it back in, the green LED flashes very rapidly multiple times, I can hear the clicking noise coming from the back, and then the red LED light comes on solid and stays on.

Does anyone have a copy of the firmware update for the WD-73734 available? I've added a Darbee to my system and I'm now getting the message about it being an AV device and not supported by Net Command. I tried the "Menu 1 2 3" trick to get into the service menu and disable Net Command but the only option available when I do that is to reset the TV back to factory defaults. My guess would be that I have to update my firmware to be able to disable Net Command? I've contacted Mitsubishi support looking for the firmware update but it seems I'm running in quicksand gong that route. Thanks!
post #1993 of 1996
My bet is there is no software update that adds an open menu feature you are asking for. My suggestions (works on my TV):
1. Disconnect your video processor.
2. Go into the TV INPUTS Menu and turn off that HDMI input (this will clear the input)
3. Connect a DVD player, cable box or satellite receiver to that HDMI input and go through the discovery process (don't bother nameing the input).
4. Now while watching the HDMI input try the MENU 123 route.
5. You can now connect the Video Processor to that HDMI input, but make sure that you turn of HDMI control in the porcessor's menu if possible.

My TV only shows the option of turning off the "NetCommand for HDMI" when looking at an HDMI input so if you are looking at componet, composite or antenna input when you go to the Reset Menu, the option to turn off NetCommand for HDMI does not appear.

That model of TV was when the HDMI CEC control feature was very new and the TV never supported the CEC feature for AVRs however the need for an easy HDMI Control Off Switch in conusmer menus was not yet established.

Well my second bulb now has 11,342 hours and time to replace. First original bulb had 14,000+.

First bulb was a Phillips, second a osram.

Where is the best place to go now for them since prices dropped tons over the years. My TV is a WD65734 from sept 2007.

Ok guys just replaced my second bulb. It was not osram, it was from diversified electronics. I replaced it at 14,288 hours wednesday.

Bought another one from them. Tv is bright again.

So far last thing i had replaced was the DLP chip which I got for $162. I installed it myself.

I am so used to the set up inside the tv I can repair anything in it.
