Philips 26PFL3404/12 (TPS2.1E-LA sasszi) nem talál adót. (megoldva)
Sziasztok! Ez a készülék még tavaly került hozzám "villámlátogatást" követően. Első körben tápegység javításon esett át, majd (hála az ittenieknek) main csere következett. Már indult a gép, de csak szép fehéren világított. T-con csere és működik, azonban a probléma összetettebb mint gondoltam mivel szükséges volt a eprom cseréje is. Jelen állapotban a hangolást leszámítva rendben dolgozik, "csak" nem talál egyetlen adót sem. Olyan mintha nem is venné észre, hogy van benne tuner. Kérdés/kérés tehát: Miként lehet ennél a szerviz menüt előcsalogatni? Reményeim szerint ott van a kutya elásva.... Köszönettel: Kiss Z.
PHILIPS 55PUS7809 power up but no image, screeen staying black
Hi everyone,

I'm trying to repair a philips 55PUS7809 with power but no picture.

After disassemblying it, I found out that a Q3 transistor had blown away on the T-Con board réf. 6870C-0502B (LG Display)

Anyone could help me finding the diagram of this board?


Thanks a lot.

04/07/2019 : I ordered the board on aliexpress.com

10 days after, I received a refurbished board with one inductor case broken. Also I had to pick up a LVDS lever from the old board to replace one missing 
on the new board.

After plugin everything back, Tv is working again !!

Bought 1400€ 5 years ago, I'm happy to fix it with only 8€ (shipment included)

THanks Aliexpress !!!

Sziasztok A fenti alaplappal szerelt gép eszi a sortranyót. Kérdésem, hogy a terheletlenül mért sor táp 160v nem sok? Izzóval is csak 10v-ot esik. Kondikat hasonló csecsebecséket cseréltem, hajtójel szép. Sortrafó? Köszönöm
