Help identify part..
I am working ona toshiba tp4871b with no schematic. Im trying to
rebuild the vertical circuit changing caps and IC"s. I tried to get a schematic from samswebite.com and they called me and told me they dont have it. So now im just looking parts up to see what they are to try to find the vertical circuitry. The part in question is labeled like this: STR S6421 SK2312A Its mounted vertically and has 8 legs and a massive heat sink. Searches on google have turned up nothing in data sheets or the part description. Any help is appreciated. TIA!! |

Just a guess, maybe you could use a STR6421 instead? Probably easier to
get.... "Ol' Duffer" skrev i melding ... In article , says... STR S6421 SK2312A STRS6421 is a voltage regulator. Unless they are doing something extremely strange, it's not the vertical IC. |

Thanks alot thats help me cross that off my list. Which means my VOT
has to be on the last PCB inside the TV. Now I just have to figure out how to discharge this projection tv. They have the anode wire running to a weird position. It looks like the wire can be pulled off of the FBT is this possible? If not i guees i will have to take this TV apart even more.

On most sets, the focus/screen divider also serves as a bleeder resistor, so it will discharge itself when off for a little while. And yes, there will be someplace where you can disconnect the anode lead, either at the flyback or the distributor. thanks I will try that since the wire looks like it can be pulled off just like a spark plug wire. |
