Question about Samsung HP-R5072 50 in. Plasma HDTV

1 Answer

Image is grany every time tv is cold.

Hi:
When I first bought the TV the image was crispy and clear at all times, now I have to let the tv warm up before the image is clear again, if the tv is cold, most of the screen get grainy and parts of the images slowly fade away for a few seconds after the image has change, after 10-15 minutes of the tv being on, it fixes it self, but It has become very annoying to have to wait until the image is back to normal every time I turn it on before I can watch a movie, any suggestions on how to fix this?

I had the same problem. Except mine never got better after the tv warmed up. I fortunately I still have my manufacturers warranty and Samsung sent a guy out within a few days. He replaced a few parts which really didn't do anything. However what he did that was interesting was on two circuit boards. One on the mid left and the other on the mid right. Apparently there is a nob or something he tweaked on each panel that cleared the grainy image right up. What he told me was that the it is basically pixels that are not turning off in sync. adjusting the two circuit boards syncs the pixels to turn on and off at the same time.

Hi,
It would be great to assist you in Sony convergence issue.
As you said, for some time TV shows bad convergence in picture that shows its matter of lose/ dry solder joints in D board, specially on convergence out ICs pins that need to be re-solder.
There are 2 big black ICs mounted on aluminum heat sink on D Board of TV, below image shows D Board location in TV.
Resolder pins of these 2 ICs and also check any other dry/ cold solder joints in circuit board. I do not think of IC replacement as problem occurs some time.
Let me know if you have additional question.
Thanks.

Red and green ghost images on screen. usually appears after tv is warmed up. TV is 8 years old. Is it worth repairing? How much to repair? I have read that it may be problems with convergence chips.


Since the problem comes on with the set warmed up the most likly cause is cold solder joints. This happens because componets heat up and cool down at differant rates and over time cause the solder conectin to break or become intermitant. The simple fix would to get the convergance IC's soldered and while in there solder up the entire high voltage section

Color red seems to be more prominant...than other


I've had this problem with my projection TV recently. I would say your lens/lamp is to blame. It might be time to change it, depends on the last time it was changed, most of the time, the TV will tell you that it needs to be changed, but not always. I think your best bet is the TV lamp.

ACER LCD monitor no image, appears white color only


Quickly go to the Acer website and check FAQ's and while there also find out how to get an RMA to return it. My guess is you have a bad monitor. At $200 roughly for a replacement I would hustle. I am assuming you got nothing but a white screen but did get video on your TV.

Picture is Rolling..stops after some warm-up


I have seen this many times. There is a 9 volt regulator on the small signal board that causes this. The regulator goes bad and the 9 volts starts dropping, especially at start-up when the regulator is cold. If the voltage is below 8 volts then the picture gets dark and the vertical becomes unstable, with the picture squeezing down and/or rolling. As the regulator warms up the voltage starts rising back towards 9 volts and the symptoms start clearing up. There are 3 regulators in a row on the board and the regulator in the middle is always the bad one. Replacing that regulator should cure your problems but it should be replaced by someone experienced in servicing Mitsubishi projection TV's because pulling the chassis out is quite tricky.
