Question about Samsung HP-R5072 50 in. Plasma HDTV

Image is grany every time tv is cold.

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?

Re: image is grany every time tv is cold.

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.

Fault in the main board. You have to replace the main board. As it's have SMD components is would be difficult to repair.

Sony pfm-42x1 flickering screen when turning tv on

OKAY I found the Problem!! Bad Caps Compositors. I Proved this in 2 ways. First I took off the Back(always make sure the TV is UNPLUG) In the photo above I put my finger on the capacitors. I found some that where NOT FLAT ON TOP(You can kinda see in the photo too). I could feel a little nipple on top.(Some times you can see if their busted open but not in this case) so I felt them and the bottom right and top left area in red in the photo where not flat. I took my dryer(My wife really) and warmed them up for about 2 minuets each then another minuet rotating back then forth. I leaned the t.v. up to lean on the frame and plug it in. I continued warming the capacitors up and in about 2 Min the T.V. has stop blinking. Much better then the 20-30 min. So the hunt for the Capacitors is on. It will be some work to get the boards out. If everything is done delicately The Soldor job is easy for me. I am going to buy the 8 but replace 1 board at a time until the TV works and put the other on the side for next time or put them up on E-bay. I hope this helped Please like if this helped you. ea0a96a3-fb82-4ec0-89f4-76b4080e9c6e.jpg 1b190ebd-5d69-4553-a009-840d29ab4c87.jpg ab9b51d0-6e1d-4cce-b822-e80d0fde9163.jpg

Black spots blocking picture on plasma TV

Main board is likely the issue or worst case is a defective main screen called a display panel. Voltage checks will not usually help with this type of problem since it will likely have to be traced with a scope.

3-5 years is average life on this type of set and Philips is known for parts at that age becoming unavailable............

I own a 40" Bravia

You should open the tv and check the power supply module, this part has the ac cord connected to it. If the picture clears after a bit, you will probably find some of the electrolytic capacitors on the module have swollen tops, these are not running within 10% of tolerance and should be changed.

You will require some soldering skills to change these parts and they must be installed in the correct polarity. Pay attention to the +- symbols on the pc board whenb replaceing caps.

TV losing its channel memory

I had the same problem. I replaced the EEPROM marked U33 (it's a 24C32 in a smd package) and the TV worked fine.
BEFORE replacing the EEPROM you have to go into the Service Menu (hold down VOL- and CH+ on the local command) and take a note of all the values, specially the R,G,B gain and R,G,B bias, in the "standard" picture mode as well as in the "Cold" picture as well as in the "Warm" picture mode.

(if you forgot to do this, here are my default values:

R gain: 434
G gain: 482
B gain: 484
R bias: 270
G bias: 270
B bias: 264

then you put the "Cold" image mode and set again those values, increasing the G bias to about 300 and the B bias to about 310.

then put the "Warm" image mode and set again those values, increasing the R bias to about 300 and the G bias to about 280)

The other values such as brightness, contrast etc, have to be left at 50.

I hope this solution will FixYa!

LCD TV/DVD Combo image washout

Instead of reloading the DVD multiple times, when the set is doing this try jaring it with the palm of your hand on a corner near where the DVD goes in. If it clears up when you tap it, maybe you just have a bad connection inside that needs repairing.
