if they are startup caps, use 47uf instead.

Re: Technica M32/57G

LVDS cable clean and seated both ends? Maybe cold solder joint under processor... Probably not T-con board IMHO...

Re: Technica M32/57G

ok tv yet again is dead all voltages fluctuating shall i change the last 2 caps (due to being from a old board) with 47uf 50v due to running out of stock with the 22uf 50v caps

Re: Technica M32/57G

i say yes.

back when i was doing satellite recievers almost production line style,
we always bumped up the startup cap to the next value.

the plus is it lasts MUCH longer before failing.
the downside on paper is it takes longer to build the initial charge for starting.
i say "on paper" because we are talking fractions of a second - so who cares!

Re: Technica M32/57G

ok thanks already done this so i changed the two old 22uf 50v caps with new 47uf 50v and now the tv is working again but im still suspecting a fault elsewhere with the psu but ill keep testing

thanks
