Do you own a Toshiba 52HM84?

post #1 of 29
Thread Starter 
Does anyone o nthis forum own the Toshiba 52HM84? If so do you conenct devices ot it via HDMI? I am having MAJOR issues with my unti and conencting devices via the HDMI in. All this is giving me a really nasty taste for HDMI.

Yes, I have a 52hm84. I feed HDMI via a Monoprice 5x1 switch. As far as HDMI connectors go, it is a little finicky. If you're having trouble, try a different cable, and you need to make sure the connector is seated perfectly. It may not fix the problem, but it's worth trying.

The biggest issue is the age of the HDMI board in the 52hm84; after all, the TV is about 4 years old or so, which, in the evolution of HDMI, is pretty old. My primary issue revolved around running HD-DVD/BD through my Onkyo TX-SR805. The HDMI input of my TV would always downconvert the audio to 2-channel PCM when the HDMI audio passthrough of the 805 was ON; in other words, I would get a picture, but only 2-channel audio through my receiver and 5.1 speakers (the TV speakers are off). When I set the 805 HDMI audio to OFF (which it should be to get HD audio decoding on the 805), I would lose the video. I called Toshiba and they confirmed that it's basically the fault of the HDMI board in the TV. You can get a replacement HDMI board and swap it out (there's a thread here on how to do that), which may or may not work. If you did it yourself it would cost about $140. I personally got around the issue by using 1x2 HDMI splitters between my components, my receiver, and the 5x1 HDMI switch, but it's kind of messy (I can get more specific if you need me to).

You can't really let this experience spoil you on HDMI specifically (although, I, too have some major issues with it); the problem is more inherent to the HDMI board in that particular TV (and probably others). I've had no problems with the HDMI on my splitters, switches, inputs/outputs on my two Onkyo TX-SR805 receivers, or the inputs on my Panasonic ae1000u front projector.

Thank you so much for you response this is a big help. Yes please give me more info on your splitter, your setup and replacing the HDMI board. this whole expericence has me quite bitter towards HDMI. here is a video of what happens when i try passing the HDMI frequency thru my reciever to my tv. this has happened with three different recievers. - http://www.youtube.com/watch?v=WvVSjUEMxIY
shown in the video is the Harman Kardon avr247 i have since exchanged it for the Yamaha RXV663 and still the same issue. what's interesting is that my equipment worked perfectly fine for the first 3 weeks then one day this issue sunndely cropped up. I have a service plan thru my local bestbuy and their tech came out to look at it and announced that my tv was too old and would not work withHDMI. he also claimed that there was no Back panel AV input replacement and no HDMI board replacement.

First, here's the link for a replacement HDMI module for the 52hm84:
http://www.partstore.com/Part/Toshib...8055X/New.aspx
I've never installed one, but if you google it, you may find some instructions to replacement so you can do it yourself (I know I've seen instructions, but I have no idea where I found them).

Your video shows what I experienced (somewhat) when I was passing HDMI through my Onkyo TX-SR805 with HDMI audio OFF (for decoding in the 805). The video would flash some image/color about every 4-5 seconds with a black screen the remaining time.

As far as my setup goes...my HDMI sources are a Toshiba HD-XA2, a PS3, and a DirecTV HR20-700. The HDMI output from each source goes to its own 1x2 splitter (I got them on eBay, fairly generic, about $45 each. Each of them requires power, so factor that in to your setup, too.). One of the outputs from each splitter goes to an Onkyo 805 HDMI input; the other output from each splitter goes to my Monoprice 5x1 HDMI switch. The HDMI ouput from the switch goes to the TV, and there's no HDMI output from the receiver. HDMI audio from the 805 is set to OFF, and HDMI monitor out is set to NO. Just designate each HDMI input to the receiver as the digital input for audio for each source (just like you would for optical or coax input).

The primary issue you might have is handshaking issues, i.e. depending on which sequence you turn on the components, the TV or the receiver may have trouble detecting the HDMI input. In my case, it's primarily the 805 that had handshaking issues, so I keep 5.1 analogs in place to switch over to if the receiver has a hard time detecting the HDMI audio; otherwise, just switching inputs and then back on the receiver usually helps.

Hope this all makes sense.

Thanks Schroedk,
You werent kidding when you said the alternative HDMI method was "involved". the whole reason for me trying to get the hdmi working is to have only one cable running to my tv and also limit the number of devices i have on my HT stand. I looked up the part you listed. I didnt find the 23148055X part listed in my Service Manual BUT i did find a part with the number 23148055. They are two different peices tho. 23148055X is the HDMI Module like you said. ( wish i had a picture of what this looks like) and 23148055 is the "SCAN CONVERTER MODUL, 03DVI MHDM01". based on that description tho it seems like they might be one and the same. I have a Bestbuy service plan, so the question now is whether or not i should have them order and replace this part and if it will even work. All these miscallenous spendings could go towards the purchase of a new set.

Oh, i Also forgot to ask. How did you manage to find someone at toshiba to answer your questions?! i have been calling and emailing them non stop and its like they are reading from a script. they keep referring me to the 1800 number, and everyone at the 1800 number keeps telling me to call an authorized toshiba service technician.
As per my service manual i accessed the service menu on my tv. and there is a field thats hilighted in red. according to the manual this is an error but it doesnt tell me what the error is!
post #7 of 29
If you've got a BB service plan, have someone come out and see the "error" in the service menu for themselves, as well as show them the flickering you get when you use the HDMI input. My guess, unless you're lucky, is the tech won't have a clue. However, if you keep pushing them, they may try to swap out the HDMI board, and/or replace the TV for a comparable unit.

I love the pic of the 52hm84 (I had it professionally calibrated), and overall it's a solid TV (once I figured out the HDMI issue I was having). I've been tempted to get a Pioneer Kuro and relegate the Toshiba to basement duty (behind my 106" FP screen), but unless I come into $3000 unexpectedly, I really can't justify it. Both SD and HD look great on the Toshiba (and we watch a lot of both).

I called the general Toshiba 800 number, used a lot of big terms that the CSR didn't understand, and she fairly quickly transferred me over to a tech.

The Toshiba is truly a great unit minus the short comings. i dont know how to describe it but something about the picture quality got me hooked. As for the service plan. i had the best buy techs come out and check the tv -TWICE! and unfortunately i was unlucky. the first time the guy said he would have to call up toshiba and call me back. I never heard from him. The second dude pretty much laughed at me and told me my tv was too old. I asked him for suggestions he said "buy a new tv"!. i think they dont care much becuase my service plan runs out in 6 months. Also neither of these "techs" even ran the service menu on my tv! amazing isnt it? I have a qeustion. when you access your service menu where it says "BLOCK........:MAIN...SUB" the word SUB is hilighted in red. according to my manual that means some sort of error but i dont know what it is.
post #10 of 29
Sorry to hear about the "techs". I avoid BB like the plague, because it seems like if you were to line up 10 applicants from best to worst, for some reason they would pick the worst to hire as their employees. I know there are some good ones, but it seems to be more of a crapshoot than anything to actually meet one of them.

However, in BB's defense (it pains me to type that), by today's standards and how fast TV technology is evolving, it is an "old TV". Now, in YOUR defense, I would be ticked off if a tech told me that, especially considering what I paid for it. Plus, if it's still under a service contract, "old" or not, they're contractually-bound to fix or replace it. Don't let them get away with their laziness, and take your complaints up the chain of command until you talk to someone that can actually help you resolve the problem to your satisfaction.

I'm not really familiar with the service menu, other than watching the ISF calibrator use it to make his adjustments, so I can't help you there.

Good luck!

gotcha. yeah i'll hold them to it. it is an old tv but i did buy it wih a HDMI port on it so i'd like for it to work prefectly. they might argue tho that if i bypass the Reciever then everything should work, which might be a good arguemnt on their part.

Man, wish I had read this before I bought the 805....has anyone gotten around this via a new HDMI board? Im having all the exact same problems...this sucks...

And so i just spoke with Toshiba tech support that told me that the HDMI to the TV is end of the line, he states it must be the Onkyo 805 that has the problem....He didnt seem very educated on the subject either...

Yeah, he had no clue. The Toshiba is definitely the problem. I've got two Onkyo TX-SR805's, and I get the same issue with both units only on the Toshiba. Both 805's work without a hitch on my Pioneer Kuro 5010fd and my Panasonic ae1000u front projector.

Hey schroedk, I followed your lead and ordered the 1x2 powered HDMI splitter and a 5x1 switch. How did yours come out after you did that?

It was a rat's nest of cords, but it worked.

Crap house mouse... same issue for me with the new TX-SR706 and the 52HM84. Has nobody tried to install that new board? Christ.

I am going to order the replacement board and will report back if that fixes the issue.

I recommend ordering the 23148055X instead of the 23148055 HDMI module. I'm not sure, but looking around the web I saw several opinions that indicate the 23148055X is a newer design with better HDMI support. Please post about your experience replacing the module. My HDMI was working fine (connected to a PS3) until a thunder storm early this week.

Well, I ordered the X version on Sept. 7th from partstore.com and just got an email this evening stating the part was backordered. No word on when it will ship--but I will post back here once I get it installed to report if it fixes this bug.
post #21 of 29
gotten it installed yet?

I have an extended warranty on my TV through OneCall... I wonder if this HDMI glitch would be covered under such warranty?
post #24 of 29
nope, Toshiba (as of about 2-3 months ago) really refused to acknowledge that there was even a problem. The "tech" kept trying to tell me it must be the Onkyo 805, I just laughed and said "ok". I have since ditched the hdmi switch and splitter, as even that didnt want to work all the time.
Ive had to use component video from ps3 and sat hd and the HDMI for audio only, pretty dumb.

Im already scoping for a new TV, bought this new at around 2800.00 and its making me sick that im going to eat almost all of that. Lesson learned though, Im steering clear of the DLPs and Toshiba.

Now that winter is approaching (my viewing primetime) I tried to order the new HDMI module, only to find it unavailable.

I may be wrong, but there may be some FTC "rule" about offering support parts for X years. If nothing else, the fact that there ever WAS a new module design should be enough to disprove Toshiba's position.

Anyone for a lawsuit?

Hi, can you give me thebest setting of Toshiba rear projector 62HM84 for personal preference.thanks a lot.
Awaiting your prompt kind comments.

It looks like they have this HDMI module at http://www.vancebaldwin.com/products/?23148055X

Not sure if they are a reputable company to order parts from though. Did all of you other 52HM84 owners get a letter recently concerning a lawsuit against Toshiba for the lamps? I received it about 2 or 3 weeks ago.

Tried to find the HDMI module part#23148055X at Baldwin and it was no longer in stock. I did find it in stock at sears parts direct.

I know this is an old thread, but I thought I'd add a little.

Short version: I had the long-standing HDMI compatibility issue between my Toshiba 62HM84 DLP TV and my Onkyo TX-SR705 receiver. I bought the updated HDMI module, installed it last weekend, and I can now run all video through my Onkyo receiver and one HDMI out to my TV.

Long version: I think I purchased the Toshiba 62HM84 DLP TV back in Nov 2004 and it's worked great (still does). Sometime in 2008, I ran into the HDMI compatibility issue when I purchased an Onkyo TX-SR705 receiver and tried to run all video into the Onkyo receiver and HDMI out to the TV. Never could get that configuration to work. The closest I could get was video with no audio, but that was it. After a lot of searching, I found this AVS thread:

http://www.avsforum.com/avs-vb/showt...38276&page=256

and on page 256 I found a mention about the Onkyo/Toshiba HDMI compatibility issue and a link to this thread. I did a lot more research to find the HDMI module and finally tracked down the module at Sears Parts Direct. However, since I had already got everything working through some creative wiring with the bluray HDMI direct to TV, and the DirecTV receiver, Xbox 360, and old Xbox all component to the Onkyo receiver, then one component out to TV (plus all the optical and digital coax cables for audio; lots of extra cables), I thought it would be best just to wait until the TV was a little older before I broke it .

I finally got around to buying the updated HDMI module from Sears Parts Direct in Feb 2010 (part number 23148055), but held off from attempting the upgrade until last weekend (23 Oct 2010). I figured since I was getting the new Xbox 360 250Gb with Kinect in a couple of weeks, this might be a good time to test my skills.

Skipping all the little details, I wasn't even sure how to get the old module out when I started, but there were a lot more screws to remove than I would have thought. Since I had never taken a TV apart before, I can say the "procedure" was interesting. After awhile, I figured out the input section of the TV was on a tray that could be slid out if I removed some more screws. Once I figured that out, things got a little easier. After moving a few wires and untying some others, I was able to get the old HDMI module out far enough to remove the four sets of cables (and that wasn't easy either; three of the four wires sets were "seated" down inside their sockets making it impossible to remove even with needle-nose pliers. I ended up having to slowing pry them out with a small flat-head screwdriver).

When I finally got the old module out, I compared it to the new one. From the outside, they were exactly the same except for the sticker on the side. The white rectangular sticker on the old module had "MHDM01" while the new module had a green rectangular sticker that had "MHDM01A", which I was guessing/hoping meant a later revision of the module which might solve my issue.

Once I put everything back together, I rewired my setup to run all video directly to the Onkyo receiver and only HDMI out to the TV. I took a large handful of wires that I hopefully no longer needed, set them aside, and fired everything up. I first went into the Onkyo receiver setup and set "HDMI Out > HDMI Monitor" to "Yes" and changed the HDMI inputs to what I had wired, set "HDMI Audio" to "Yes", and hoped for the best. To my great surprise, I had video and audio for the first time through HDMI out from the Onkyo to the TV.

So hopefully, next week when I get the new Xbox 360, I'll plug it into my last remaining HDMI-IN on the Onkyo and everything will work fine (the DirecTV receiver and bluray player take up the first two). I'll post back to let everyone know how it goes (well, if anyone is even reading this thread at this point).

Just want to say, without AVS Forum and all the people posting here, this wouldn't have been possible, so thanks.
