I have a 3 yr old 42" Samsung, which has worked flawlessly to date. In the last cpl of days I am getting some slightly blurred image on the right side and also some reddish, green or pinkish shadowing (or overlapping) on words or images. It is most noticable on white words like on my expressvu satellite guide. I would say the overlay is about 3 mm in lenght. Can I adjust this myself? If so what would I do? Thanks

I assume this is a crt-based RPTV? Have you done a manual convergence on this TV? If not, that may help.

However, be aware that a lot of the older CRT-RPTVs have been having convergence IC issues. See the sticky on that subject at the top of the Hitachi forum.

I thought I posted a response but its not here...oh well.. I am a electonics tech by trade but I have never touched a tv before, (business equipment for me.) How would I do a manual convergence? I know I can get into the service menu by mute 1-8-2 but I am lost from there. Can you give me the steps or maybe a link? I don't know a lot about tv technology but I am sure its CRT based. Thanks for your response.

Sorry, I can't help you, perhaps someone else can. I have the following other suggestions.

1. Is there a user manual convergence in the regular operating manual?
2. Is there a "magic focus" button or something similar which does 4-8 points automatically?
3. Purchase a service manual (I bought mine from the place I bought my TV for about $30)
4. See the warnings in the Digital Home FAQ "Service Codes" (under help).

Brooker · 2006-08-20, 02:02 PM

Tthere is a self focus button you can press, the tv automatically self focuses after you turn it on after a few minutes. It used to make it perfect before, but like I said I get what you call bleeding, mostly noticably on text. Hopefully someone can give me a few more answers. Thanks

After I last wrote I had a blue line shadowing white text. I went into the mode where you push mute 1,8,2 with the TV powered on (it gives you a grid that you can move around on the screen) and then pushed 9 for blue, I was just playing around with it and accidentally saved the setting after I had moved the grid location. Anyway the tv was suddenly back to where it was before with decent quality. I then went into service mode, power off, mute,1,8,2, power on and just wrote down every setting. There is a listing you can edit called Convergence & NR. Can anyone that owns this tv or another close to it tell me how they would run a manual convergence in this section?

I have similar problem with mine earlier this year, lucky I bought the 5 years extended warrenty from BB, they send in a guy and found out it was the ic on the circuit board on the right hand side if you look at the TV from behind, the guy ordered the whole board instead since it was under warrenty, he told me if no warrenty the part and labour would cost around $500 and he told me the design of the heatsink on that board is not good for prolong usage, they should have a fan blowing at it. He told me if I am going to use it for more than 4 hours, I should turn it off for 20 minutes.

Brooker · 2006-09-18, 12:55 PM

Wow...my tv is on probably from 9:00 am to 11:00PM just about every day. The blue cast I have now is not too bad. It is mostly noticable when there is a black image surrounded by a white background. I also see it when there are black bars on the side of the screen like when a show is on in 4:3 format. So do you happen to know what the part is called?

apvm · 2006-09-24, 09:47 PM

I have no idea, it is the board on the right hand side if you look at the tv back side. I think it was the board which control the red/green/blue thingy. Before replacing the part, auto focus will not complete.

If I were you, best reason to tell wifey we need a new TV :-D

Brooker · 2006-09-25, 07:53 AM

Well maybe thats not my problem because my tv still does autofocus with no problem. My tv is actually only 2 years old this month. Anyone else have any suggestions to cure a blue haze or shadowing on some images? It seems to happen most when there is a dark image(ex. man in a black jacket with a white blackground. Around the outside edge of the jacket there would be a blue haze) Could it be a convergence problem? Any suggestions appreciated.
Again it is RPTV CRT Samsung 42".

I have exactly the same TV. I had three issues with it but but for the most part I am happy with it.

1) TV developed a green screen. A technician came and fixed it.
2) After that I noticed that the self-focus routine stopped working and the top left corner was discoloured. Another technician came and fiddled with the convergence. Discolouration disappeared.
3) Then I noticed that the bottom screen was being cut-off. So the score ticker on the score/tsn/sportsnet was cut off!

I didn't want to call another technician so I used what information I remember from the Technician fixing my TV and also the information from the above thread and did a manual convergence. Now I can see the scores again and as an added bonus. The PQ has improved a lot!!!!!

Please be careful, you can severely mess up the TV if you don't know what you're doing and I had very sweaty palms until I was comfortable with it.

With the TV On, mute 1-8-3 brings you to the convergence grid. But before doing it, please read the thread carefully.

Please note there are two convergence settings for the TV. One for 480i/p and one for 1080i. The TV will automatically detect what's coming in the input and switch to that mode. So if you want to change your 1080i mode convergence, you have to feed in from your HD box. If you want to change your 480i/p convergence, you have to feed in from your DVD player.

Also before you exit out of the convergence menu mode, you have to run the autofocus routine in the convergence grid mode or your auto focus mode will not work in normal tv mode anymore.

One last warning. Convergence setting mode is REALLY REALLY tedious but once you figure it out, it's definitely worth it.

Ok,

I have been into the convergence screen several times. Am I suppose to push #1 to run the convgence? When I push 1 all my lines are really out of sync. It is like a bow on all 4 sides with the middle part of each side bowed toward the middle. Kinda like this shape- ) ( on all sides. The colored lines are not in sync at all. Still I do have a good picture, other than the blue haze at times. I do know how to adjust it with the volume and channel selector buttons, I just want to know if you hit #1 first and adjust from that screen. Also all the lines (Red,green,blue) are suppose to be merged into one line from top to bottom?

videobee · 2006-09-26, 11:59 PM

No you don't have to hit 1 before adjusting the convergence. 1~3 keys allow you to revert to presaved convergence settings. I believe 1 changes it to no convergence compensation. 2 changes it to factory default and 3 changes to the last saved settings.

If you get into trouble, you can revert back to the last saved setting (unless you saved) by hitting 3.

If your convergence adjustment is perfect you will see a perfectly white grid where you can't see any individual colour anywhere. If you see any colours, that colour must be adjusted so that it blends in with the other colours.

Brooker · 2006-09-27, 02:43 PM

I have problems now, I had hit #1 and it displayed a really misaligned grid. I was in the middle of adjusting the green line on this screen when the screen went all fuzzy, the tv then shut off. When I turned it on again the screen was way off convergence, now I cannot adjust my green line from left to right, only up and down. As a result my screen is bowed in the middle when looking at my sattelite guide. The colours are still fine, and I was able to adjust my red and blue to match the green lines and the HD channels are still good. If I watch a 4:3 show I have to stretch it or it will be bowed also like this ) ( the screen along the top is fine. Do I have board problems?

That didn't happen to me. Can you hit "3" on the remote control? If you didn't hit the add/del button, it should revert back to the original setting saved in your TV. I did it and everything went back to normal before I continued my adjustments.
