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.

SOURCE: 42FD9954 philips plasma TV flashing LED it wont come on

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%.

SOURCE: samsung 42' plasma tv,screen keep flashing, blurry,no pics

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.

SOURCE: sony 42 inch plasma tv standby light just flashes tv

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.

Hello there, I have a 50" Samsung Plasma TV. There is weird horizontal colours at the bottom of the screen. Can this be fixed eazialy? Thanks Jodie.


I've had this happen recently. Can it be fixed, yes. However, it takes a good amount of work. Worse case senario, if you can find no one who can fix it, you would have to get another tv as this wold be a problem with the hardware of the tv.

Hello
You are talking about the plasma display of Samsung [Samsung Syncmaster] I understands. Specify the connections you have done to it to receive cable TV with this set. I can/t see any description about the reciving system [ PAL, SECAM, NTSC4.43, NTSC3.58] etc, from the manual of your display. Here in India, system adopted for all type of transmissions is PAL BG. Will your Plasma Display is compactable with this system/ If so it must rreceive the Cable TV here in India. Otherwise a converter may be needed. Please send me details of your plasma display reciveint system. Is it multisystem comatable? Give me details plelase. Give me the connection details that have don with that display also. OK.

I'm connecting my laptop to my plasma tv to watch


It sounds like the cable is faulty. I presume it is a VGA cable as these are prone to wires breaking inside and colours going missing. Try bending the cable around a bit esp. near the connectors and see if the colour flashes on and off as you do this. If so you might be able to temporarily fix it if you can find a position for the cable where the colours are all working and tape the cable in this position. It might also mean than a pin is missing in one of the connectors.

Either way, I reckon you are going to need a new cable.
