Needs new convergence ships, part number stk 392-040, there is 2 of them, replace them both, also check fuses on the board, you probably need a tv repairman to fix this.

LG rear projection colours out of alignment


I have a similar problem with an LG (except my red is the one that is fine) and was able to talk to a tech in some detail about it. The tech prefaced by saying that he had done a hundred or so of these with exactly the same issue. This is very common and the life span of rear projection televisions is not great. Having said that, plasmas and LCDs are also limited in life span mostly due to modern high performance gaming machines which shorten the lifespan of monitors both plasma and LCD alike.

From what I have gathered, this is not a problem that you can easliy sort out. (Of course they would say that though) It involves replacing the digital board which means soldering followed by aligning the lamps which requires quote a lot of expertise.

The part itself apparently costs around $200 Australian and the labour will vary for the cost of the technician but I was quoted that the labour was about the same cost as the part.

Not sure if I would call this solved but I hope it has been at least a little helpful.

Samsung tv SP42W4HB fails t power on!Please help!


Typically a convergence amp fails and causes the shutdown. There are two to handle the job so when one goes both should be replaced. This failure may also damage associated fuses and resistors.

MODEL NO SP42W4HB PICTURE DISTORTED TOP AND RIGHT SIDE COLOURED SHADOWS COLOURED WAVY LINES TOP THIRD SCREEN PINK AND GREEN


This is most likely a convergence problem. You should see 2 large black ICs in side attached to a heatsink. They will be marked STK392-010. Try resoldering the pins on these ICs first. If that does not resolve the problem, replace them. These parts will be about $20 each.
Keep us posted.

I would check the CRT socket module for Cracked solder joints. If not you may be in the early stages of the CRT shorting, If so you will need a new CRT.
