Have been a long time lurker of the forum and follower of EEVBlog but thought I would join up mainly to document this for others.
My 8 year old Philips 32TA1000 LCD TV recently started behaving strangely - either resetting and then failing to display a picture until powered on/off, or displaying rainbow snow, or corrupting the colour mapping, so green was red, etc.
This was quite intermittent for a while, and led to me changing cables etc., to no avail. It then started happening the same time other devices came on, so when the fridge compressor kicked in the TV would trigger, likewise with the subwoofer coming on.
This led me to think it was a capacitor issue, so I opened it up to see if I could see any dodgy caps, however they all looked OK to me. But I decided to order some in and give it a go - I ordered a new set (apart from the tuner decoupling and audio stages, both of which I don't use) of through-hole Electrolytics from Farnell, all low ESR Rubycon, Nichicon and Panasonics to replace the crappy Capxon and Elite ones Philips put in there.
I fitted them yesterday and all has been fine so far! Probably wouldn't have had to courage to do it if it wasn't for some of Dave's recapping videos and seeing how it worked for him, as this is our main TV.
Was a good excuse to order $45 worth of stuff from Farnell for the free postage, after seeking wife approval of course.
