convergence problem 42h82

[Raji]

My old Big screen tv started acting weird, the whole screen will sometimes be entirely horizontal lines (which they will switch from red horizontal lines to blue and back). I've read a little on this and what I am seeing is to replace the SMT caps, and was wondering how do you identify values on SMD caps?

the caps I am looking at replacing are:
u4
100
16v

2b
10
16v

t1
100
6v

i am assuming theses are all 16v and 6v, 100uf and 10uf, but what does u4, 2b, and t1 mean???

Re: convergence problem 42h82

is that your toshiba with this notorious model? yes mostly the 10uF SMD caps are the responsible for this. Also change out 100uF and some 470uF. I use standard radial caps and legs bent outwards and trimmed and soldered to the pads, standing up. Also it is vital that to resolder whole convergence area including the wire jumpers on the circuit board (small signal mainboard) near inductor coils.

yep its a toshiba
