Ok, fixed two of these TV's so far and there is a lot of work involved in repairing them. Total parts cost for both that I have done is £16 in capacitors from RS and about 2 hours of work.
Firstly looking at the psu I noticed that almost every cap on the output was blown (capxon and Decon). I fully recapped the psu with rubycon, ichicon, chemicon and Panasonic I also replaced every smaller cap on the psu as they were also starting to go very bad. There are several caps hidden under the heatsinks that you MUST replace on the psu.
When ever I get a tv with bad caps on the psu I always check the caps on the mainboard..... Glad I did on these !
Over 35 caps on the mainboard were exploded, they were all this crappy decon brand. Every 220uf and 100uf 16v caps were exploded and blown out the bottom as well as the lager ones with vents. Over half of the caps that I replaced were completely open no esr or capacitance at all, just zapped. You need good soldering equipment and experience to be able to work on a set up like this. You must replace every blown cap as it can cause further issues. Overall junk tv that needs a lot of work but at least they are working pieces of junk. Here is a link to a video on the first one of these I repaired:
