I have had the HR20 for at least a couple years now, using it with an HLP5674. Within the last year or so, all of my SD channels became so completely overscanned that I cannot even read subtitles, or see the score of a game. It did not used to do this, but I guess one of the updates has caused this.

Is there a fix for this? I have run through the screen sizes on the TV menu, that helps only slightly, there is still significant cutoff.

It seems like there should be some way to adjust the HR20, but I have not found it. I'm connecting with HDMI. Sounds like a DirecTv/HR20 issue, not the TV.

I need some help with my 5674 set, for some reason, after an hour of tv on, the whole screen gets really fuzzy enough that i can't see anything and then i have to turn off the tv for a couple hours for it to cool down for the screen to be clear, of course, until it gets hot again.. has anyone experience this?

You'll have to be a bit more specific about "fuzzy". If you look closely at individual pixels, do they drift out of focus, or does this look more like image degradation? Is this specific to a certain input, or does it affect all of them?

Gary

i'm sorry, i meant fuzzy cause i couldnt really see the screen anymore cause of all the things that was happening.. the screen would start flashing colors and the colors flashed everywhere, sometimes images would move around the screen to different locations.. i would hear a buzzing noise too after i shut off the tv and turn it back on..

Oh dear, that sounds really bad. It may be a bad digital board or DMD board. Probably needs repairs.

The DMD board is not currently listed. Its part of the far more expensive light engine. The DMD board requires careful handling and special alignment.

Please bear in mind that I am making an educated guess as to the cause. It would take an experienced technician to accurately diagnose the problem, and he would have to see your picture symptoms first.

The "buzzing noise" you described could be a color wheel going bad, or maybe the power supply - it depends on the type of sound. Either of those could potentially affect the picture as well.

I hope this is the correct place to post this question, as I am a forum newbie.

I have a 4-year old Samsung HLP5674W which I have really enjoyed until now. Since about a week ago, I do not get a picture. When I turn on the TV, it powers up as normal, the sound and picture both come on as usual, then after about 3 seconds, there is a brief green flash and the picture goes off. Everything else (sound, channel changing) seems to work OK, just no picture.

Has anyone had a similar experience or is familiar with this type of problem and can offer any advice? I would normally have requested service under my extended warranty, but I purchased it from Tweeter, which is now defunct.

Thanks in advance for any help in this matter.

Have a HL-P5674W with a fan #1 failure message on the screen. It turns on brieflly and has a normal picture until it turns itself off.

Does anyone know where this fan is located and if it can be repaired or replaced easy enough by someone not afraid to open the set up (me)?

Thank you.

Replace the bulb it's going bad and TV will shut off automatically..

We are buying a house where the seller is leaving behind a HL-P567AW on it's stand if I want it.

He says it has a fan failure message (I think he said fan number 1) on the screen but that it turns on brieflly and has a normal picture until it turns itself off. Is this a known problem with these sets, is it easily reapairable?

Thank you.
Color wheel fan probably is bad not to hard to fix but you can do it in 1/2 hour.
Google JANGO and there detail of how to do it.

I have a 4674 that has worked without any problem for 4 years but...it is getting very hard to get the set to turn on or off. Have new Duracells in the remote but still the same. I have to get within 4-5 feet and carefully aim to get it to work. Otherwise works great as usual. Any ideas?

biggiE48, can you be more specific regarding JANGO, JANGO.com seems to be a music site not a TV repair site?

Thank you.

Sorry I missed your message, eastreal. This sounds like the lamp/balast going bad. Hope you've managed to fix it by now.

Anyone have an idea? See post above by me.

I have to get within 4-5 feet and carefully aim to get it to work. Otherwise works great as usual. Any ideas? The IR sensor is down by the light-engine, so the remote has to be aimed at the middle of the screen (the IR bounces off the mirror inside). If you're aiming properly, there are 3 possible causes:
If its only the ON/OFF button that has the trouble, it could be that the button is not working properly. The worst problem for remote buttons is food grease (esp. pizza) that migrates into the remote and gets between the button and the PC Board contacts. You may be able to open it up, and clean the button and contacts with alcohol.
The IR transmitter diode is fading and needs replacement. A whole new remote may be easier. If you have a universal remote, try programming it with the Samsung remote, and see if the universal is better. If not, then your Samsung remote is not the problem.
The IR sensor is getting coated with dust, and needs cleaning. A few careful blasts of compressed air can blow the dust out of the light-engine, sensor and colorwheel area, and restore a dimming picture too.

Can anyone confirm on a 5674 that the color wheel fan is fan #1? I have a fan#1 failure message on the screen.

Thank you.

Hello, Have not posted here in a while but I have a Sammy 4674 which I bought new back in 2004. I have only changed the bulb once in that time frame and the set still works good. The sound is better that most sets out there today I believe and the picture quality is still very good compared to Plasma and LCD, however I am considering buying another TV. I am looking at a 47" Vizio LCD SV470M with a 120HZ refresh rate and contrast ratio of 50,000 to 1. The price is less that a grand a lot less that the 2500 I paid for the Sammy five years ago. What a difference a few years make. Paul D

After 4+ years I finally had to put a new bulb in my 5674. 14,875 hours is not bad. I did not notice how dim it had gotten until I put the new one in. WOW!

I have an HLP4674W. Just changed the bulb but problem still exists.

1. Plug TV in

2. Red standby light on

3. turn on TV

4. sound but no picture

5. green lamp light flashes (MIDDLE ONE)

6. goes into standby (red light)

7. TV turns off by itself

8. Immediately turns on by itself

9. repeats steps 4-7
10. turns off by itself

11. all 3 lights flashing

12. after 2 minutes no fan and TV goes dead (just red standby light)

13. turn TV on - goes back to step 4 and repeats.


Any ideas?

I don't recall the exact sequence, but mine intermittently did something very similar in the last month or two before the bulb died. It hasn't happened in the ~3 months since I replaced the bulb. Maybe the replacement bulb you put in is bad?
