Hope it helps.

most home depots will have a replacement ballast for this light, inside of box will have the correct wiring diagram, and how to wire it, if not sure as to how to wire it call an electrician

Here is a list of equialent batteries that are calimed to be able to replace the one you specify.

Equivalent Batteries Cross Reference: Duracell DL-1/3N, 3N, Ray-O-Vac 867, 2L76, Energizer 2L76BP, 2L76-BP, CR1108, IEC CR11108, CR1-3N, DL1-3N, Dantona Comp 15, Duracell DL1/3N, NL1/3N, Energizer LR1/3N, Eveready 2L76, L76BP, I.E.C. 3V CR1/3N, CR1/3N, CR11108, Innotek M041101, Kodak K58L, National HM-N, NR-52, NEDA 5008L, 5008LC, Nikon F-1, Sony CR1/3N, Varta CR1/3N, LaserMax LMS-1/3N, LaserMax LMS-1/3N 5PK, LaserMax LMS-UNI-G

On page 10 you will find the power supply. You will likely find a failure among the components:

D4, D5, D6, D7, C1 or C2

There could also be a circuit board crack around these items.

C1 or C2 is the most probable failure. They are 2200mfd/25 volt electrolytics.

yes they both the same part number one is board number and other is manufacturer number, board number is what it is and manufacture number is if its in other tvs.

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).

I hope help you with this. Good luck (remember ratde this help).

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.

It's not a 1k Resistor but a 10k...it's the resistor R3 on the Circuit Board Part Number RPB-4434ZA (P/N: 23122468). If you don' replace the resistor you will keep burning your lamp. If you decide to replace the resistor by yourself...you should take the time to look at all the on the back of the board. This Board is made by the company Rubicon Corporation for Toshiba and it's a issue on the Toshiba DLP TV (62-52HMX84). If you don't wanna do the job yourself..bring your TV to a repair and give him the part number of the board and ask him to replace the board for you. If the price is higher than $350.00 go somewhere else...He try to fu....^&*%*%&%.
