1) Gas Ignition
two) Picture Development
IGNITION: Power Supply > Logic Control > Z or X Sustain > Screen
PICTURE DEVELOPMENT: Power Supply > Video Control Lath or Scaler > Logic Control Board > Y Sustain > Ten Sustain > Buffer Boards > Screen
Common issues with plasma panels: Electrodes damage inside, change gas parameters, drivers on ribbon connectors impairment.
Typical Bad Plasma Screen Symptoms:
- Flashing scarlet dots or pixels on the screen when it is cold (after warm upward information technology goes away)
- Distorted colors on part of the screen. Left or Right Corner.
- Colored vertical lines on the picture
- Flashing red dots on some part of the screen.
xc% of the screen problems are not repairable
10% on panels 42V6 and 42V5, at that place'south a chance to repair it.
Burn down-in prototype:
This is an Image you can see on top of the normal picture.
It's unremarkably displayed every bit dark lines or a dark expanse on the screen.

A plasma TV is a very hard working device. It is working harder than any Boob tube that has been built before, and as a effect – information technology produces a lot of heat.
75% of the technical problems in our shop on plasma Television set'due south are caused past overheating problems.
If there is no agile cooling system, about of them die in the first 3-six years.
Always ask at the store before ownership if there is a cooling system inside.
No cooling fans inside = no long life.

A existent exam in a shop:
PHILIPS 42 pf7220a/37. After x work without a cooling system, some of the components on the power supply board were out of temperature balance. Vs voltage changes upwardly to 2 volts plus. This may lead to an overheating problem and cause other permanent damages.
