If you want to add, all you do is TIP- Bonus me...I get more of the TIP than the posted Labor
The ratio is 75 / 50. I think that's why the other guys emphasize "A tip is greatly appreciated" Me, I look at it as I chose to do it for the Labor...
And so...a BONUS is greatly appreciated !
Also note, a Cat 3 or Cat 4 is really only to let you know the maximum voltage level a meter can handle...You need to handle 250 Volts for the Vs Voltage and everything else is a lot less..
As long as it handles 250 Volts DC we're good....
Now, where should we get started? Let's make sure all the power voltages are at the power supply. It's redundant if the TV repairman left the new power board in, but we don't know that for sure....
I kinda prefer to do pictures because I generally save about a thousand words. So if I'm not answering quickly, I'm working with pictures, and I generally take a good hour to get them ready.
Ok, First thing, let's get you familiar with your TV set. Set it in an area where you have good lighting, an AC plug and a table with some room on it.
Next, remove the screws out ot the back, and leave it on the stand for testing. Make sure you can plug it in, and hopefully look at the screen and the blinking LED.
Now once you remove the BACK -- Here is where your BOARDS are located and the PLUGS are located.
We will be testing the power supply first to make sure our power supplies are working.
Ok, now...on the back of your TV set, remove the power cord and then remove the connectors highlighted in green and circled in YELLOW....this disconnects the entire PANEL DRIVE system and leaves the Fans, the A board and D board RUNNING.
Check this Jumper--- MOVE it over to P 12 Connector on the power supply board.
Plug it back in, and Turn it on --- Do the Fans stay running? All four of them?
Does it shut down? Does it blink a different code?
If if stays ON --- then measure these points on the plugs located on the P board.
P Plugs are on P-board, SS plugs on the SS board , and remember that PIN 1 is always the UNIQUE -colored wire on a plug....like if you have ALL BLUE wires, then Pin 1 will be WHITE or a different color
Check these voltages on the power board
