Hi folks,

Note that both Sparky and C/J too have had the same positive result - awful glad, but I've changed those caps more than once and it didn't do the biz fer me.

Trying to keep the faith - and hoping - Chris

Hi all, just had a similar problem (brief picture then only sound) with a Mikomi LCD15796F tv purchased from Argos in 2007 and in particular the inverter section of the 17ips01-2 module. It was a set waiting to be thrown out or be repaired and thanks to this site I replaced the three offending blue capacitors with some new safety certified Murata types from Farnell CPC (one day service) and now it works perfectly again. A 4.7pF type was not available so I used two 10pF in series, which is across the transformer coil output, so having an advantage of not stressing them so much as for one on it's own. Although these caps are rated at 3kV, it is possible with aging that they break down, short-circuit and shut the inverter off. Not a difficult job to fix except the solder pads are a little flimsy and so care required when de-soldering the old capacitors. Luckily the other parts of the circuit were undamaged.
