post #6331 of 6625
I took my tv apart and cleaned the mirror and lens, checked and cleaned the screen assembly, removed the lamp and cleaned the lamp area. No change in my yellow blob issue, which does look different than a dust issue, which has happened in the past. There was a little junk on the mirror and some dust around the lamp assembly, but otherwise it was pretty clean in there. I am going to wait for a while longer to call Mack about service for these blobs, but I find it more and more discouraging to see a degraded picture every time I watch it. It really did have an excellent image until now.

I was watching my tv early yesterday and turned it off. The tv was off for a few maybe 5-7 minutes and then we had a brown out. When I turned on the tv later I wasn't getting sound. I tried messing with the cable box and tried different sources and inputs but still no sound. I was using video 1 and tried video 2 after that with the same results. Any idea what could have happened? Is it possible that the brown out fried my inputs. I have the tv on a ups and it is surge protected so I'm not sured what happened.
post #6333 of 6625
Figured out my sound problem. Some how the center channel input got changed. I just had to toggle it and the sound was restored.

Had a service call on my HD-70FH97 last week. Yellow discoloration over much of the screen. It already had one light engine replaced due to bad geometry. The service tech said it needs another light engine and gave me a $1780 estimate. I turned it into Visa warranty and they bought out the contract.

Looks like my only option today is a Mitsubishi. Looking at the WD-73737 or WD-73738 if it's released soon. I don't see any other options being sold today.

Not sure what I'll do with the JVC (the warranty company told me to dispose of it).

What does that mean? I'm just curious, since I also have an extended warranty through Visa.

No problems with my TV so far though, knock on wood.

I originally paid $2600 for the JVC. The repair estimate was $1780. The offered to pay the $1780 for the repair, or $2000 to buy out the contract. So I could repair the set for $1780 and have the remainder of the Visa warranty (one year) or I could take the $2000 and do whatever I wanted with the money, but Visa's warranty ends.

I took the buyout because I can buy a new Mitsubishi WD-73737 73" set with a five year extended warranty for about $2000. I'll put the JVC on craigslist (with full disclosure of course) and see if someone is willing to put up with the yellow discoloration. The discoloration bothers me, but my wife can't even see it.
post #6337 of 6625
Thanks for the info. Glad to hear that they took care of you. That $2k buyout seems like a no-brainer.

This is a phenomena common with those individuals that lack the y chromosome-my wife dosen't notice the yellow discoloration in the lower right corner of our set either, but my eyes are drawn to it constantly now.

Unfortunately, mine became noticeable just after the 2 warranty extension expired-it's going to have to get a lot worse before I get the go ahead for a new set.

Anyone know a way to hasten the process?

I have a 70" fh 97 set. I am looking to upgrade to a front projection system.

The set is about 4 years old.

What's it worth? I have the JVC stand with it as well.

I am not going to post it here, it's to damn big to ship. But was
just looking for some input.

Well here's probably the upper end of what you can get:
http://cgi.ebay.com/JVC-HD-70FH97-70...item27b0f51668

I'm no expert, but I suspect you would be hard pressed to get more than $600-$800 if you try to sell locally. Unfortunately, Craigslist is just full of people selling big screens for peanuts.

That buyout is a much better deal than I got from Mack. I am sure you realize that the Mits is a DLP set not LCOS like the JVC. That was the attraction with JVC (Plasma flat panel quality) at 1/3 the price. As you pointed out you can get LCOS on a front projector still but everyone has gotten out of rear projection because LCD's have caught up and Plasma, especailly the Panasonic G series have come down in cost with many good reviews ( although plasma seems destined to fade in favor of LCD as well). good luck with your hunt!

I see bad LCD-RPs on Craigspam regularly. Those that know the problem and are honest sell them for $50-100, and they probably go, esp 50" and over. Some that are unaware of the situation or maybe not too honest say something like 'needs tuneup' and ask for a couple hundred, which I doubt they get. There might be someone out there that really does need just the tuner board, for example, or parents that don't care too much about the quality of the picture if it's a tv for the kids to play video games in the basement. There are also breakdown ebay sellers that pick tvs up cheap, disassemble and sell the pieces. Even if you leave it out for the garbage man, that's where it could end up anyway.

The replacement Mitsubishi 73" hasn't been delivered yet, but I have two offers for the JVC 70". One is a neighbor and the other is a friend. I've told both about the yellow area and neither say they can see it well enough to care. I'd prefer to sell it to a stranger so I haven't committed to either yet.

Both are in the $500 range.

Thanks AVS forum. Our 56" set from Costco is about 6 years old, and just had the first lamp replacement. We bought the lamp from an Amazon seller when we got the warning message, then waited until the set died.

After we replaced the lamp (very easy), the set still didn't work so we put in a service call. Turns out it was the ballast. While the tech was at our home, I suggested the mirror and lens cleaning described on this thread. We had a lot of dust motes before and between the new lamp and cleaning, our TV looks brand new now.

I wouldn't have thought to ask for the mirror and lens cleaning without this forum, so thank you very much. Just call me a Learning Lurker!

Here's an update:
I bought a Mitsubishi WD-73737 as a replacement for my JVC HD-70FH97 and had it installed Friday.

Well I can say the JVC had a far superior picture. I miss it already. The Mitsubishi gets grainy on fast action, the top corners are dim when compared to the center, and straight lines (like viewing in letterbox) are not perfectly straight like they were on the JVC.

The plus side of the Mitsubishi is that it's quieter. Not much else to say.

Thanks for the review. That's good to know. I was considering replacing my 61" JVC with the 72" Mits because of the size and price.

I think I'll keep the JVC for a while longer then....
post #6347 of 6625
Thinking about selling this to get a projector, how much should I ask for it? I've had it since maybe late 07 early 08 and still on original bulb with no issues.

Still have the remote from when I turned in the TV a year ago...anyone need an extra? Shipping plus a buck or two and it is yours...PM me

Guys, i have found the source of the "yellow" blob! See the picture I have attached! Its the first color filter on the optical block failing due to the UV radiation from the lamp. I cant believe my picture was still working with this melted chunk blocking the light. I think I might have a source for the part to replace this, but have to wait until Monday. From what I have gathered, this is the blue color filter (polarizing lens). I removed it, cleaned the melted residue off the optical block and reinstalled it all just to see what the result was. I now have a blob free, crystal clear picture... without any blue . Hopefully I can source out a blue filter that will work and replace it. Hell, I am tempted to try a blue polarizing lens from a SLR camera just for kicks.

Guys, if I can find a source for this part, I will gladly let you all know. And honestly, its really easy to take apart and put back together. I honestly can have the light engine fully disassembled and reinstalled in less than an hour!

post #6350 of 6625
Wow, did you have a fan fail or was the set unplugged before the cool-down completed?

My "blob" hasn't gotten any worse over the last couple of years. The set now has over 4000 hours on it.

I would be extremely interested if you find a parts source for the light engine.
post #6351 of 6625
Nice work, Cowboy!

Please let us know if you find the replacement part, I'm holding on to my 61FN97 (hopefully) till the new wave of 3D sets has been worked out.

This would be a life saver if the yellow blob rears its ugly head again (I'm on my 4th or 5th LE... all were replaced within warranty... and this last one was replaced AFTER warranty by JVC after I complained). So I basically sit in fear of the yellow monster rearing its ugly head again.
post #6352 of 6625
Alright, it definitely is the blue filter that is trashed. I put a polarizing lens in its place (the kind for a digital camera, broke it too... there goes 40 bucks!) But it does bring back the blue tint, but almost makes the screen black! So, the polarized lens it to much, but its a step in the right direction.

As far as my TV, its just under 4k hours. It is on its second LE. I never unplug it and all the fans are working as designed as far as I know. One thing many of you with the blob problem should check is your bulb. I replaced mine as I thought it may have been creating the blob, only to find the blob to be worse after swapping the bulb. What I found is that the Original bulb was failing. The mirrored coating inside the bulb was starting to flake off in chunks. I am wondering if this was causing the light focal point to be off, thus causing a "hot spot" on the filter lens. Not quite sure yet, but I think that might be the problem. I have a call into a company that makes these filters, and hopefully will hear from them on Monday.

I had started another thread on here that is the same problem, but figured I should bring it to here for all to see. There is a response there from someone that seems to know exactly what he is talking about and its a bit disheartening as to what he had to say, but I am not about to give up just yet.!

Any new status on the filter?

By the way, if you take out the filter to clean it, will it permanently damage it?
post #6355 of 6625
Wow, awesome find...don't leave us hanging! Need a DYI on getting to this, and hopefully a source for the filter. No Blob on mine, but with nothing close on the horizon as a replacement..I plan on keeping it going a long time.

I sold my Optoma 65" to my parents and moved my JVC into the bedroom as I rarely watch TV in there anyway, just play Xbox from time to time. Figured I'll keep my eyes open for a used Color engine for it.

I tell ya though, its frustrating that it would fail in this way. It seems that it is a design flaw with as many "yellow blob" posts there are, and I know for a fact that its caused by what I had happen.
post #6357 of 6625
Well, after 3.5 years of trouble free service the "change bulb" warning message popped up last nite. I have noticed the pic was not as bright as it used to be, so not totally unexpected.

I don't want to replace it with a cheapo bulb, but have noticed the Phillips bulbs are a lot less then the OEM JVC replacements. From what I've been reading Phillips makes the OEM bulb anyway - is that right ? Hate to think I paid $60 more for the JVC name on the box
post #6358 of 6625
When I bought my last bulb I read that the original JVC bulbs had an issue that caused premature failure and that the new model of bulbs fixed it; but I don't remember the exact info to look for to get the right type. Search here a bit more; that info should still be here.

A couple of pages back, there are two places that sell good part, one is from "Electrified" and the other is:
