Update:
I further took apart this abomination, got deep into its guts down to the fluorescent tubes of the backlight.
I connected everything with its guts taken apart.
Please note that this panel doesnt have tab bonds on the sides or bottom, only on top. I tried to mess with the bonds (pressing, wiggling etc) in the 'warmup-phase' with the fault visible. Didnt make any difference.
Then I waited till the fault went away and started to ice components....

Telefunken T37P884 FHD 100 DVB-T horizontal corruption
This is a Telefunken T37p884 (Vestel chassis/boards) with LG panel.
PSU working with stable rails, TVset turns on but has horizontal lines/picture corruption.
Backlight inverter, PSU, Upscaler and TCon are good. (at least I presume that because I replaced the PSU, Upscaler and TCon boards with reviewed used ones from a spare part shop)
The corruptions cover the entire screen (the tvsets own menu display too) and so they obviously also occur on every signal source.
The upper few rows of pixels are always good.
These corruptions... -

I think I'll open a new thread about this issue since this isnt about the PSU anymore. Thread-hijacking is a bad habit of mine >_>Leave a comment:

Re: 17pw26-4 psu
Quick solution: Bought a good one on ebay, because I've not enough time left to mingle around with this tv. I'll keep the faulty PSU and report back here if I can bring it to life again. Oh and yeah, its an LG panel. I witnessed something: The picture corruption goes away if I let it sit turned on for a few minutes. It continued to run flawlessly for a few hours until I put it into standby again. This morning I verified this, it showed the exact same behavior. Horizontal corruptions which vanished after a few minutes. Also measured the power rails of the PSU under...Last edited by BenTennyson; 09-18-2016, 04:15 AM.Leave a comment:
