SOURCE: Zenith A25A11D No Red Color

Hi, If you are comfortable working with a soldering iron, a continuity (VOM) multi tester and a fair knowledge of electronic components, then perhaps you can repair the missing color red. You have to open the unit, expose the small printed circuit board that is attached to the small end of the picture tube. There will be many components present but you will need to focus yourself on three (3) transistors that are bigger than the others sometimes with an aluminum heatsink. It is also possible that instead of 3 transistors you will have one power IC. In any case these control and provide the drive for the 3 colors of your picture tube: red, green and blue. One of them is either dead or suffers from cold solder to any or all of its pins/legs. You have to visually inspect the solder joints of these big transistors/IC and determine if any is dull in color, loose of simply not connected. You may even try the shotgun approach and solder each of the pins/terminals/legs just as long as you don't cross solder creating a short between pins/legs. If this works, you're set, if not: You have to check with the use of the VOM and determine which of the 3 transistor is defective. If you are familiar checking continuity of base to collector to emitter and reverse, again you're set, if not perhaps you check all three and compare which have the same reading from the same position and which is different. Pls keep in mind the transistors have forward and reverse bias readings. If able to determine defective component, desolder, replace and solder. If it were an IC, replace the entire pack. If the above would make you uncomfortable, pls ask for the services of a qualified TV repair man and explain your problem. Hope this works out for you and give you some ideas. Pls post again how things turn up, good luck and kind regards.

This is a known defect that Samsung should correct at no cost to you whether or not your TV is under warranty. Contact Samsung at their 800-Samsung and tell them you have the 'white dot' problem - advise them that there is an alert on this issue. My TV is over 3 years old and they are taking care of it; just waiting for the part at the moment.

After warm-up screen flashes and loses color but comes back on and off intermittidly. This is a 50" Zenith Plasma tv. thanks.


Sounds as if a cable connection is bad. Check the cables first. If cable are good, change inputs, if cables are bad replace cables. If it's component, make sure that red, blue or green didn't come loose on both sides...the tv and the source. If you still have problems, check for red video noise on the screen itself, preferably when it's on but with on input (black) If you notice this, your plasma is failing.

Red Dots


This is know as diffusion. You will need to locate the Vs adjustment inside the TV and vary it up and down by NO MORE THAN 10 volts. If this does not correct the problem then you will need to replace the Plasma panel.

Blue dots on my lcdtv


Sometimes the voltage can be set to high by the factory. Throughout time, blue dots will appear. You will have to remove the back cover off the tv, find the "voltage Screws (they are labeled) and turn down (left) JUST A Notch. Have seen this done many times.

Pray that the panel isn't blown out or bad projector tubes. They are expensive.

Blue dots and screen flicker are VERY common on the newer LCD and Plasmas

Also, if you have a pixel setting on your TV (not sure if that one has it) Try setting it to
480p.
