Samsung PN50A450 Offical Owners Thread. - Page 101

post #3001 of 3158
I have an old PowerMac G4 (quicksilver) with an Nvidia Geforce 2 MX Twinview monitor. I have bought a Belkin ADC (apple display connector) to DVI adapter and used my DVI to HDMI connector to attach it to HDMI2 on my TV.

However, the TV never shows HDMI2 as available on my Samsung PN50A450.

Using the same cable, but my mini-DVI to DVI cable, I am able to connect my MacBook just fine.

I have manually configured the Mac's settings for the monitor (which it is detecting and using a SAMSUNG color profile) to match the HDMI/DVI input display modes in the manual (resolution, hz, vz, pixel frequencies and refresh rate). i have tried settings for several of the resolutions, etc. None of them trigger HDMI2 to show as active on the TV.

I have attempted to make some changes in the service menu to see if it would help. They didn't (so i changed them back). However, when enabling "PC" mode in the EDID setting (with my TV on and HDMI1 selected, and the computer still connected to HDMI2), while it is "waiting" to test the connections, the PC video momentarily flashes over the HDMI1 connection.

Any ideas?

Hi all,

I've been a lurker of this forum since I got my Samsung PN42A450 plasma in May 2008. Lots of great information found here, including colour calibration settings. Thanks for that! I am currently using Smeg's colour settings and they look great.

I'm hoping someone might be able to enlighten me on something I recently noticed on the TV. On dark scenes or dark frames I've noticed a faint white-ish glow along the right side of the TV screen. It's glow isn't very wide, maybe less than an 1/8 of an inch. (It's not distracting from the main picture but I'm kind of anal about those sorts of things. Is this something I should be concerned about and call the place I purchased it from or Samsung while I still have warranty? What causes it? I searched Google for this type of issue on plasma screens but found nothing so thought I would ask here.

Some info on my uses of the TV. It's for TV and DVD's only. I don't game on it. It's on daily for approximately 2-5 hours. I have it on surge protected powerbar and it's unplugged at night/during workday.

**update...Tonight looking closer at the picture I notice there is a row of red pixels along the right side of the screen where the glow is. Guess I'll be calling Samsung.


Thanks for any insight on this!
H.

HGHLNDR , I have the same problem ( read about it 3 posts back page 100) and I'm wondering if it's worth calling about no responses yet.

I have the same thing; although it started as just a bit of a glow coming from the edge of the screen. Over time it became a "reddish cloud" effect that took up about 2 inches of my screen from the right-side.

Called Samsung, and they got a repair man out to service it. The repair guy first replaced the Y-board, and after that didnt fix the problem, Samsung instructed them to replace the panel (and shipped the repair guy a new panel to do so).

Got the TV back last Friday and the problem is even worse, although this time it's on the LEFT side of my screen taking up about 4 inches from the left side of my screen.

So now Samsung is calling yet another repair guy out tomorrow to look at my tv. The repair guy called me and after I told him the situation with the first repair guy, he was surprised that Samsung authorized the 1st repair guy to replace the panel, because he said that usually in that case, they just give the customer a new tv.

Anyways, I'm a little peeved that Samsung decided to arrange another service call instead of just giving me a new tv, but I'll see what the repair guy says tomorrow.

Hey rinse sorry to hear that you have to get another service call, how long did it take for the faint white glow to turn into a red cloud. Although it is taking awhile you'll get a new tv out of it at least maybe speak to a manager to see if they can just do it now.

I've had the tv for about a year and noticed the glow about 6 months in, it just got progressively worse.

Technician didn't take my TV away today, he just took a picture and said that he would have to talk to a Samsung technician. Says that if Samsung already tried to replace the panel with the first repair guy, he's thinking they will have to just give me a new tv now and there's not much else they can do.

I'll just have to wait to hear back from them.

Check out the 42B450 thread, 1 guy had the same problems your going through now and got the new one. It's a intersting read.

When I try to hook up the cable either coax or HD cables I get this rather large spark. So I am unable to Watch tv. I can how ever play games and watch DVDs. Does anybody know why the coax cable is sparking when I try to hook it up? The house is old, it only has a 2 Wire electrical wires going to all the outlets( no earth ground).

I took the tv back to the store and it worked great there.
A CRT tv works in the house.
I used to have a Sony Plasma In the same spot i am trying to hook up a new Samsung Plasma, Put I had Dish network, now I have comcast cable.
Comcast was out yesterday and _ no problems with the cable line

I am still not sure where to start 1st.

if you've got a digital voltage meter, it would be a good experiment to see if you have voltage from the ground sheild of the cable coax to the case ground on the tv. I've seen ground loops before, but not significant arching like you describe.

Hi all,

I have just bought a used A450 at good deal and the picture is great and it replaced our 32" LCD. If I run into any trouble do I need to have the purchase receipt to get the samsung warrenty or the tech at home?

Thanks in advance

Ive had my 50a450 for a few months now and love it. had a 42a450 and got the red cloud issue they tried to fix it and eventually sent me a 50" as a replacement. so a win win for me. hope this one doesnt get it.
post #3013 of 3158
Well, these idiots are going to try and replace the panel AGAIN.

Wow.

Just a followup now that the tech was in to look at my 42A450. Samsung knows of this cloud/red pixel/growing red blob issue and the fix they got the tech to do on my tv was to reduce the voltage on one of the boards from 208 to 204. It made the glow and red pixels disappear.

Was told to keep an eye on it, if it returns to call them or Samsung again.

***update from last night. The red pixels are gone but in the low light (night) I could still see the white glow from the right side of the screen when there were dark scenes. Looks like I'm not done with Samsung Support just yet!

Just reported the same issue to Samsung (Canada) support and got off the phone with local service centre and they told me that they are aware of the issue on the service bulliten and have to replace the logic board at my home. They'll call in a couple of weeks when the part arrives. They say it will fix the problem... we'll see. I think I'll show the tech this thread when he's here.

I've have my PN50A450 for about 6 months and I just started noticing within the last month that i'll set my picture mode to "Standard" and every time I turn the TV off, when I turn it back on it's back to "Dynamic". Also i've noticed on occasion that during the middle of use it will jump back to "Dynamic". Has anyone ran into this issue before? I've looked all over the internet but found no info.

See my posts on the last two pages; seems to be a known problem with the A450's.

choose menu, setup, plug & play and choose the 'home' option -- my guess is that someone chose demo at some point.

Awesome. Thanks that fixed my problem! Now hopefully I can get rid of the IR caused by the set constantly being on Dynamic.

My saga continues, even after the service centre recommended to Samsung that they replace my TV; they've been ordered to try and replace the panel again to see if the problem will go away.

So they came to pick up my TV yesterday.

I made my first call to Samsung back on Aug 5th, since then the TV has been at the shop on 3 different occasions with the problem getting worse each time I get the TV back.

Needless to say, a pretty bad in-warranty experience with Samsung.
post #3023 of 3158
yep, I just kept my red-cloud disaster instead of having it torn apart over and over. I know -some- have received a replacement set, but my world is:
if I didn't have -bad- luck, I'd have no luck at all.
i know, sux to be me, hehe... sure was nice when it was new, now I couldn't give it away.
b'byee samsung..

Anyone else get uneven aging on the PN50A450?

I have had mine for 10 months now, did proper break in, and now I see both sides of the TV about 3 inches in it is much brighter especially the white so whenever there is light background there are vertical lines down and it looks like IR, I have tried running scrolling overnight but still cannot get rid of it

it is still under warranty but not sure if Samsung will do anything about it, basically the center of the screen is more aged because I watched a lot more 4:3 TV I guess
post #3025 of 3158
had mine since nov. '08. i too have the thin white lines that are visable, but i just run the screen burn in proctetion tools occasionally and those lines leave for a while until my family starts watching more 4:3 stuff. as long as it is fixable i am ok with it. (i run the scrolling tool for about 10 hours at a time).

post #3027 of 3158

Well tomorrow they are coming in the morning to replace my logic board, this will fix the known issue according to the service centre. I have heard they are good according to customers at work so hope this fixes it as I've noticed the red glow has gotten a little bigger.

Well they actually replaced the panel in my home. The tech stated that most repair guys (are lazy) would just re-calibrate the poles on the board because it only takes a few minutes as opposed to about 45 minutes. He preferred to replace the panel because the other way would just generate another service call. Some customers get screwed because of a lazy tech just cutting corners with a re-cab so the problem will come back after the warranty has expired. Hope this fixes it for good. I got pics of the tv apart I'll upload soon.
post #3030 of 3158
Same here Warwick, the panel was ordered for my 42". They won't replace the board in my home, instead they are picking up the tv and doing the repairs at their shop. Hopefully this fixes the problem and it doesn't reoccur once my warranty is up!
