Default Mistubishi 50803 HDTV Upgrade: It works!

For anyone who bought a first generation 803 series 4:3 set from Mitsubishi and has been wondering if there is a way to migrate towards TRUE HD without having to buy a new set or pay $300 for the RGB-CV10 or $999 for the Promise Module:

You can get HDTV with a $15 cable and any receiver with an RGB output. I bought a Samsung DTV 360 reciever to test with. Connected to the BNC inputs on the Mits with a simple RGB to BNC cable. Set the receiver to output 1080i only via RGB, and set the 50803 to HD on the DTV port through the service menu (I believe the command is Menu; 1-3-7-0 and select DTV and cycle from AUTO to HD).

Worked like a charm. HD OTA and DirecTV on my Gen1 HD set in all its 1080i glory. Saw one issue of concern in that there appeared to be a color 'flutter' occasionally where faces got a magenta cast only momentarily etc., but didn't have chance to play around long enough to determine if it was the reciever, cables, settings, or a real compatibility (sync) concern.

I'll post once the final install is complete (I'm returning the Sam-360 since DTV is bringing out a new reciever with my upgrade and OTA antenna).

I know others in this forum have commented on this issue in the past, but it's near-impossible to find FIRM confirmation that this will work anywhere on the web. SO, here it is.

It's a shame that Mitsubishi won't tell customers of this possibility, but would rather gouge you for the RGBCV10 at $300. As I said, it's nearly impossible to find data on this issue ANYWHERE.

PS> I have the Mitsubishi HD-1080 off-air receiver and have been using it for months because I thought it was the only way to get HD into my set. I was able to reconnect it after this test, revert the DTV input to AUTO, and get HD with it no problem, so it would appear that the TEST did not damage or permanently alter the set in any way. HOWEVER, it's important to note that the 803 series presents a TRUE 1080i image (black bars top and bottom) in the center of the screen, which means that prolonged HD viewing will AGE the phosphors in those areas faster than the top/bottom borders resulting in a visible 'burn-in' line during 4:3 viewing.

Hope this helps someone!

You are not kidding about lack of info on this. I have a vs-50803 and have been wondering about those 5 BNC connectors.

Seems you have proven that this can accept standard HDTV 1080i input. That would be nice. Any updates?

I'm thinking about getting a HDTV receiver card for my PC so I can capture, edit, and burn DVD's. It would seem, from you post, that if I can get a video adapter that drives 1080i out its RGB connector, all I need is a RGB to 5 BNC cable. Then manually set the TV for this input.

Sound right?

Thanks for posting, I was starting to think I was the only fool trying to tinker with this.

Default A Little More Help....

I received a receiver from Comcast and don't know hoe to do the 1080i setting approach. Any thoughts? And where can I get one of these cables.

Sorry to be so dense....

Default Need Help

OK, so I have gotten the cable, ignored the H and V inputs on the VS50800, have the setting for the STbox at 1080i and still nothing.

On my set, there is no DTV port setting..., I can only think the H and V connectors need something that my Motorola settop box doesn't provide. Any ideas?

Thanks,

Default Found the same issue

Hi Sport73 and all
I have the Mitsubishi vs-60803. I purchased the Samsung 360ts HDTV receiver 3 weeks ago. I used a 15pinRGB to RGBHV BNC cable to see if it works. Well it does, however I do get the same magenta color in the center of the screen. This usually happens when there the scene changes quickly, especially when I am watching a football game.

My question is, does this have to do with an inferior cable or is it a sync problem. Do they make a DVI to RGBHV cable that I could try?

Your help in this would greatly be appreciated.

Thanks
Robert

i have bought 2 rgb-cv10 adapter modules and i can't get either one to work. i have a vs-50803 mitsu 6 year old hd tv. i hooked up the rgb-cv10 correctly and no red light goes on. i have a dish 811 hd receiver. i have checked the dish output and it puts out a 1080i signal. can i just get a 5 pin bnc cable to component video (RGB) and not use the damn $300 adapter module? i tried the menu 1-3-7-0 command and see where you can cycle thru the dtv input to hd but it shows zero signal strength when using the dreaded rgb-cv10. sport73, it seems too good to be true that i can by-pass the rgb-cv10 with a rgb to bnc cable. i guess you get these at a electronic store?? also seems that not using the "hd control" computer type cable supplied also is not necessary also??? i guess it is worth a try but you seem to have it working. now at least i know how to turn on the dtv input by using your instructions. can you add anything else?? will the dish 811 output a "compatible" 1080i signal? hopefully i don't need a mitsu hd box!! many thanks in advance jack8219

You don't need the RGB CV10. Any receiver with an RGB output that allows a fixed output resolution of 1080i should work. I tried with both the Samsung 360 and the RCA DTC210. The RCA DID NOT have the magenta cast discussed in my initial post and the follow up, so I would recommend it over the Samsung. Picture quality from the RCA DTC210 was PERFECT.
Again the setup is RGB to BNC (5 cable R,G,B,H,V) breakout. Reciever set to 1080i (30hz). Menu 1-3-7-0 to set DTV port to HD instead of AUTO. done.

Ignore the CV10 and look for a reciever with a 1080i 15-pin dsub RGB output (made for TV/30hz refresh; vs. PC RGB out which will refresh at higher rates). Get the breakout cable and enjoy.

Hi Sport73
This is very interesting information, I will look into the RCA DTC210. I was planning to purchase the RGB-CV10. May be I will buy the RCA and sell my Samsung unit. I must say I love the picture on the Mitsu, but the Magenta is driving me crazy. I did not know there was a difference between PC RGB and dSUB RGB. I wish I new it before I purchased it.
Thanks for the valuable information.

Robert

sport: my dish 811 has "component" out jacks only. are these RGB? will your breakout cable work with a component red, green blue jacks? is there a difference between rgb and component jacks? i am returning the damn rgb-cv10 boxes and plan on giving your "breakout" cables a try. i assume you get these at electronic supply stores or go on online? where did you get yours? my neighbor has dsub jacks on his OTA hd receiver but i of course do not have this type of jack. thanks jack

Default RGB-CV10 boxes

Jack 8219,

Let me know if you would want to sell one of the RGB - CV10 boxes if they can not take them back. I could probably use it for my Mitsu set. I can give you me email address.

Thanks
Robert

For clarification, RGB refers to PC-style VGA output (15-pin computer monitor connection) broken into a RGB+HV signal via the breakout cable.

This output is not common on digital cable boxes, but fairly common with DirecTV recievers.

This does not work with component video signals (3 RCA-style cables with Red, Green, Blue colors).

i tried hooking up the mitsu vs50803 using a zenith hdv-420 OTA receiver using rgb to the 5 pin bnc connectors and got a picture but it had a horrible green cast all over the screen. the bad thing is i messed up the convergence in the service menu (i know i should have not touched it but i was fooling around trying to get rid of the green). to make matters worse i messed up my dish dvr by unplugging it. hope it resets and comes back to life. i am going to try a real mitsu service guy to reset convergence and see if he can make the rgb-cv10 give me HD. i am screwed if this not work as i offered to get a new "real" HD tv but my lady friend who owns the mitsu wants to keep it. so i guess if everything fails i will not see HD for a long time.

If I recall correctly, you can reset your convergence right from within the Convergence Menu (not part of service mode).

Also, If you get your PVR up and running check to see if it's outputting ONLY 1080i (the only signal the set will accept) and check the specs on the RGB (again, PC style, NOT component YPbPr!).

Both recievers I tried worked using the method described.
