Hi chaps,
Intermittent fault on a Samsung CRT TV.
I`ve traced it to an overheating component in the PS
It sits around the rectifier area and is the only one on the board.
Its blue, cube shaped and has 2 legs. Approx 1cm high and 1/2 cm square.
Marked with `J29` and `P190`. Also has a trade mark `SH` ?

Any thoughts on what it is and spares availability ?
Many thanks.
H.
