Question about Televison & Video
Hello.i have a tv plasma neovia neopl4200es but inside is all samsung.i have a problem with the display because i don't have colours with it should be,and the image is a little bit flashing Before was working good but started to flash a little bit and now is it like this.
Sounds like supply voltage problem to its display panel. Every plasma display panel will have its own Va & Vs voltages; which will be marked at the silk screen on the display panel itself. It might differ from panel to panel. Even a slight difference in these voltages, will cause unexpected display nature. This is true to all Plasma TVs; irrespective of its brand and screen size.
Adjustment to these two voltages are there with its main power supply regulator board. You should be fully aware about these adjustment; I recommend.

The problem is in the standby power supply. the standby power supply generates the 9 volts and the 5 volts requird by the tv. If you measure the 9 volts source, with only the red light on, the correct voltage is 9 volts. However if the 9 volt measures 6.5 to 7 volts it is too low and the startup relays cannot operate. My set is a model 42FR9954/17S. In this set if capicator, 2603, is heated the voltage climbs to 9 volts and the relays work. If cold air is applied to the capicator the relays fail to operate. Replace capacitor 2503 and the problen is fixed. This capicator is: 47 Ufd, rated @ 450 volts, and is 20%.

I'm not really sure what causes this but I might be able to help.
I have an LG 42 plasma which had the same problem. In my case I removed the video and the tuner board (they both were mounted on the same frame which was screwed on the tv chassis) and installed them in a "wooden box" so that there would be no electrical contact with the rest of the chassis except from the cables connected to them. It now works fine.

You might have a bad B board. What's worse is that the power switch is connected to the Q board which works in conjunction with the B board. Replace B board, You can send your B board for repair to a company called modus link pts. They are the largest part supplier of after market parts and repair.
