Question about Toshiba TheaterWide 52HM84 52" Rear Projection HDTV-Ready Television
I have removed the light, then took out the two screws holding the plug that the ballast plugs into, removed the same metal plate holding the plug, but still could not get to the ballast. It is located behind another metal plate and seems to be screwed to the chassis. However, I got both two screws removed from this chasis, but it will not budge or slide out so I can not get to the ballast. I then took off the back of the set (13 screws) and I can slide the whole assembly partly back, but still can not totally access the ballast because again this perforated metal plate is in my way. Any suggestions?

SOURCE: ballast replacement
Your set uses the Phillips UPH100W 1.3 100http://servicemanuals.vstore.ca/ 1amp bulb part number 6912V00006A which uses Ballast EUC 6913V0002A and the actual ballast isMB03CA part number 6871VSMB13F I would contact LG and give them these numbers. Is your ballast bad or is the BallastEUC bad? Let me know if I can help you further.

SOURCE: Cant find a ballast
The ballast is actually a switch mode power supply that powers the lamp. It is an
integral part of the light engine and is not replaceable. The light engine has a price
tag of $950. If you replaced the lamp with an after market one and not the Toshiba
lamp you can experience the same problem. Some of the after market lamps will
not fire at the same voltage as the Toshiba. The blue led will come on solid and the
yellow blinking. It will try to start 8 times then give up.

I found R3 on the original board to be open, along with reading an open on CR1, D5 and D6. All the other transistors and the transformer check out. The only thing I have to do now is find out the specs of the diodes. The replacement board also had CR1, D5 and D6 open (R3 was OK). There had been some threads on various locations where remanufactured boards had bad components (the transistors were changed but not some of the other components).

SOURCE: Ballast UART Error
Same thing happened to me. After one minute of running, lamp shuts off and 5 power led blinks and 3 ready led blinks, indicate UART ballast error. Well, I purchased a new lamp, and installed it, and the problem was gone. I looked closely at my old lamp, and it showed a little blister inside, and a tiny spot of white residue, perhaps it was the whole problem there, although I don
