Hi, I used the 17pw15-8 because it supplied all the correct voltages and you could use some of the mounting holes. And I had it spare.  I had a power loom for the 17pw and just used that.  Cut and spliced the wiring making my own wiring loom.  Tv is still going strong 2 years later.  If memory serves you could use the original inverter connectors, but I would be doing a visual check before and making a wiring diagram before you start.

Only other thing I did was give the 17pw some new caps on the most likely ones to go.

Also just had a look at the picture.  What mainboard is in the TV?  Looks like a one Ive had problems with before.  If so that was the cap on the top left of the mainboard.  The cap needed to be replaced and resoldered on both sides (the one I had wasn't connecting to the top of the mainborad under the cap).  I actually ran a wire from the top of the board to the bottom just to make the link.

That was a 42" Technica TV with an LG screen.

hi rebel thanks for the advice i will check tomorrow but i think making a loom and buyong a 17pw15-8 might be a bridge too far for me
dave i will check tomorrow night and post back to you
i have found a direct replacement psu for £50 but not sure if to go with it as tv is quite old

Turnip:
Hi B/S,

Not sure that anyone has admitted original P/S make and model.

Incidentally, have a good 17PW15-8 from a screen smash, but curious about the original P/S - Chris

hi chris thanks for the offer on the psu  ,i now have a working psu and am getting good readings but it still wont switch on  :41:
i think it might be logging an invertor fault due to the bulged caps on the master and slave i have now replaced but does anyone know how to get in service mode ?
