Coppell TV Repair LLC offers you the a replacement set for modules 4921QP1046B / 4921QP1047B used in some 60'' and 50'' sustain boards powering certain LG plasma displays.
The kit contains replacements for the pair of voltage regulator (called IPMs, from intelligent power modules) IC7 and IC8, respectively called ER IPM and SUS IPM.
You will NOT be receiving the actual board shown on some images for reference and example of traces of burned components.
The modules you will receive may not be labeled 4921QP1046B and 4921QP1047B, but since the two have different pin layout you can't mix or confuse them.
There are several different manufacturers of the IPMs and there are different versions of componetns by each manufacturer.
After having serviced over a thousand of boards using those IPMs we can claim that there are no better and worse modules in regards to lifespan or quality by design and production; we have seen enough boards with both LG and Sanyo installed OEM and they all fail in due time.
Because of market dynamics we can not guarantee you which model of IPMs you will receive; we can only guarantee you that those are the best we could source and that we ourselves use them in our repairs.
As long as you replace both of them it doesn't make any difference what was previously on your board.
Make sure you read the warranty conditions section to know what to do if you do not like what you receive.
Applying this kit requires advanced soldering skills and appropriate equipment. A 50W soldering iron for $15 won't cut it and a 100W iron is more likely to damage the board than help do the job.
We do not guarantee that this kit is all that your board needs! Based on solid experience we claim there is about 80% chance this is all you need. 1 in 5 will need additional components and they vary!
There is NO WARRANTY on the components once they get soldered on a board! You can returned them for exchange or refund , but only prior to soldering them on a board. We are well aware this is not a common practive, but dare claim we've serviced more boards than probably all other vendors combined and we give them the right to lose money any way they want.
