Re: blury

It is, in my opinion a bad power supply. Low voltage can cause strange things in picture tube driven projection sets. I am guseeing the ubit uses a trippler for all the tubes from one flyback to supply high voltage to 32kv. Low volts can cause convergence and bluring of images due to beam current strength.

Re: blury

Your problem could be a bad focus pack, a bad convergence board or a problem in the power supply board. If you know how to read a schematic diagram, I suggest that, that is the first thing you should invest in. If you do not understand how to service solid state circuit boards, read a schematic, or use a multimeter, my best advice to you would be to call in a servicer for Samsung, as there is a lot of high voltage inside these puppies even when you unplug them. This is not a place to be experiementing around inside of. Good Luck with this repair.

Poor picture quality

Hello Paul. I have this same monitor, but rebranded, Access the service menu with the remote control:

With user’s RC
1. Power TV On
2. Press Menu button and call up User OSD Menu
3. Select Sound-> Balance
4. When Balance value is “0”,Enter 0->5->3 ->2 in sequence.
Note: If necessary, re-do number keys.
5. Factory OSD appears.
6. Press the standby button then AC turn off and restart the TV, which can exit factory
OSD menu.

Now you will be able to change the values for Red Green and Blue channels. I also hated this TV, but after adjusting the colors it's looking great! Hope you could fix it too! :)

It shuts its self off picture is still great everything works great it just makes a loud pop and shuts its self off i can turn it back on after a few minutes sometimes it shuts off again minutes later and...

saw a similar problem w/a Samsung and eventually the Focus Transformer gave out w/a big electric pop sound and all power went out. So it's probably related to a problem with high voltage and Flyback issue. Hope that helps a little.

Blury picture

Check the connections on the CRT circuit boards. there is a red wire that slides into the white plastic socket make sure that is connected good, If that doesnt help you may need a replacement focus block, But if so they are very cheap and very easy to install, and I can post a link where you can get one if you need it.

Samsung HC-P4752W Blurry ONLY on HD Channels

Similar problem, then about 2 weeks later the SD convergence went out. Changes convergence Amps,,, Now I'm trying to learn what 2 red flashes mean now when I try to power it up,,, it flashes twice then shut down into standby mode,,, I got no picture after installing STK392-040 chips, thinking about trying another set as atleast I had blury picture before. No solder shorts of opens that I can find. TV has always been a pain,,, locking up once in a while such that you can't change modes,,,
