My TV screen is blank for my 62" Toshiba
I just replaced the ballast in my 52HM84, working fine now. My 2 cents:
Remove the lamp. Remove the lower back panel (13 screws), remove the housing behind the lamp door (2 screws).
I only slid the light engine out a few inches, enough though that I had to remove the plastic panel oriented horizontally between the projector lens and the backside of the tv.
You dont need to remove the screws that hold the lamp plug.
The ballast board is held down by 4 plastic retaining clips, push each gently to release the board from the aluminum housing. You do not need to unscrew the aluminum housing from the light engine tray. ( Be patient, read on )
Disconnect the 2 cables attached to the ballast board.
I know you are thinking, how do I remove the ballast board with the lamp plug where it is.
Orient the lamp plug on your new ballast to match the old and use a piece of tape to mark the top wire of the 2 lamp plug wires. Not sure that it matters, but why take the chance.
On you new ballast, find the tiny hole above each larger conductor hole, poke a paperclip in the small hole to release the wire. I've done it with a paperclip, you may try to use a pin or needle. Repeat on the old plug.
Your ballast is free at last.
Put the new ballast in place over the 4 plastic guide pins (part of the plastic retainer), the board should click into place.
Attach the cables to the board.
Insert the lamp wires into the back of the lamp plug, you did mark the top one right?
I won't bore you with the rest, because you've already been there.
The biggest mistake I made was allowing the housing that has the door interlock switch to fall off the table. Of course, this pulled the plug off the circuit board and it's not the light engine board either. Didn't know it had detached until I powered up and got the LED's blinking indicating the door was not properly secured. So I had some extra stupid work to re-attach it.
But I have LIGHT.
