Samsung PLASMA PN50B530S2F DEAD

[Super360]

Hi everyone I have this plasma here that has no standby light and is completely dead. I opened it up to see extremely dirty and dusty to which I cleaned but made no difference. So I checked all fuses good. I checked the standby voltage 5 volts good. Then I did that plasma control board test by shorting the pins(THANKS 2 TVTIMMY) and the tv actually turned on and made a sound. Does this mean I need a new motherboard?

Will it need a new eeprom?

When it turns on, There is a faint ghosting on the horizontal. I'm not sure if that's normal or what is causing that? IGNORE THE PURPLE LIGHT FROM IR ON PHONE.

Ok update. At first It showed no signs of power but now it's acting like it wants to work again even turned on to the static tv screen wow. It actually looked so nice too. I didn't even notice the faint ghosting when it actually displays a image. I think the eeprom is acting erratically so I think best course of action is buy a new eeprom from glorious ebay.

A little trick I used for the eeprom was flood both sides of the eepprom chip with lead solder use flux. After both sides were flooded with solder and the board was still warm. I used a heatgun at exactly 500f. Slowly warmed the chip up from a distance then went in for the kill and got closer while maintaing slight pressure with a metal pick so I know when the solder is molten. Once it was slid it off like nothing. Then used desoldering braid on the pads to make them flat. The new chip went in like a breeze.
