Question about Samsung HCN5527W 55" Rear Projection Television

1 Answer

Color appears to change every 10-20 seconds

Hello Experts,
I seem to have an issue with the color changing very slightly every 10-20 seconds on my HCN5527W(purchased Oct 2003, warranty just ended Oct 2007). It's not very noticable but I do see it especially when I change channels and the banner at the bottom (Blue - with channel description etc.. ) seems to change slightly and causes the picture to look more tinted. It eventually returns to normal, but will become tinted, then back to normal. Also, the perfect focus appears to get to 41%, and never seems to be able to get to 100%. The manual option appears to be fine for both the Red and Blue. Not sure if there is an issue with this as well. Any suggestions are greatly appreciated.
Thanks,
JC

    The problem started when I tried to connect a computer to the DVI connection. Played with a few settings, ie 60Hz to 75Hz. I was unable to synch a picture correctly once I made the display setting changes, I reconnected my cable box. That's when I started noticing the color tint problem... I must have damaged something by changing the display settings from the computer.
    Do you think that could have caused the convergence module to fail? Thanks in advance.....

This is either a problem in the convergence regulator circuit or the convergence module

Sync problem with denon dns3000


I'm having a similar problem with my denon dp-300f. It seems to *ever so slightly* increase or decrease in speed (and therefore pitch)...I might not even notice it very often if I wasn't listening to my favorites. I have not found a solution to this problem, but my hunch is related to the power source. Meaning: I think the voltage output by my apartment is slightly sagging (<120V, AC ~60Hz...which most appliances can deal with) and this affects the speed of the motor that drives the belt. I'm looking into isolating this factor. I'll let you know.

The problem I am having is that my 32' Sony Wega kv32fs12 Trinitron television will work almost perfectly. Image color is beautiful. tuners seem to be working like a charm, but the screen has a slight...


Picture alignments made in servive menu.

pwr off + display + 5 + (+vol) + pwr on
You must do all within 1 second.
1&4 move thru settings, 6&3 chg value,
muting & enter saves chgs.

Your code access could differ.

In the menu note down all existing settings.
Make small adjustments and watch what happens if not in right direction reset that particular option to original value before you changed. In those menus you can bend, shift hor. and vert., etc.
But be warned only slight adjustments and write down start values before experimenting. Or you can get in to serious trouble.

Good secret service menues keep an access counter for manufacturer/dealer to see how many times it was used.

You may just have a loose connection. you can move around slightly and see if you see a change. Be carefull thou, not to damage anything else. Check to see if CRT boards are on neck of tube(press upward slightly) Hope this helps
