Check the solder only around the flyback area because that could make a set work off and on

In looking at the PCBs in my non-working tv, there is a good amount of white hardened stuff. What is that?


The white powder is most likely caused by oxidation. There are a variety of reasons why it would occur. Solder contains zinc, and when exposed to the atmosphere will form zinc oxide. The white powder is mostly likely zinc oxide.

If you live near the ocean, it could be salt crytals.

Tv comes on as always with piture then the piture goes out in 2 seconds


HELLO it sounds like a couple of things could be wrong. you could have what they call a dry socket or a bad, cold solder joint. what it means is that on the power supply section of the chassis the tv has gotten so hot that the solder has melted away frrom its connection and it is not making true contact on the chassis. if you know how to solder you can fix this yourself.. you will need some 60/40 rosin core solder and a soldering gun that is not over 40 watts. you will need to go over the connections on the chassis in the power supply section. hope this helps you just remember you must unplug your set before working on it. GOOD LUCK

Its a fairly easy repair, However be careful where you get the ICs alot of places sell the cheap versions. You can get good quality ICs at the link I am posting I am one of their support techs plus they offer free tech support to help you. You will need to STK392-560 ICs for your model. The ICs arent that hard to solder getting them out is the hardest but if you grab some de-solder wick from radio shack its actauul alot easier. Heres a link where you can get quality ICs if youd like. They also have the service manual for your model if youd like one. They email the service manuals.
