Hello, this small tv is equipped with mainboard TP.MS3663S.PA671 ,25Q64 flash SPI ,display V236BJ1-P01 Rev. CB When it starts, it restarts, sometimes it doesn't "leave" from st.by, so maybe we can find an update software on usb (or dump for 25Q64). Thank you
Sziasztok.
Gondom van a fent említett készülékkel.
A típus nem jut eszembe de du. felírom.
Szemrevételezéskor rögtön látszott hogy
az összes 250-450v os kondi letolta a bugyiját,
az egyik 450v 330m kondinak teteje átégett
és bekapcsoláskor áthúzott.
Kicseréltem a kondikat amikre több hetet vártam
mert extra a méretük az ár sem volt kevés a
kilenc db. kondi tízezer körül volt .
Bekapcsoláskor áthúzáshang automata le,és ua.
a helyen ahol az átégett tetejű kondi volt
púpos lett a kondi.
Nem látok sehol áthúzásnyomot pedig ekkora hangnál
legalább tíz kilovolt körül kell lennie.
olyan mintha a kondiban húzott volna át.
Ha tudtok kérem segítsetek,előre is köszi.

MODEL: PS42C7HD
FAULT: The plasma display shows no picture or the picture has significant maldischarge. Maldischarge includes unlit patches of display, overly bright parts, sparkling/unstable pixels or unlit pixels on colour bands.
DIAGNOSIS: Requires an oscilloscope. Should check Y-main waveform (was only about 20Vp-p when I checked it, should be >400Vp-p)
FIX: Replace 100uF 50V cap near yellow trafo on Y-main board
--Also encountered this fault with same model--
MODEL: PS42C7HD
FAULT: Clicking relay, no picture or sound
DIAGNOSIS: Identify shorted sustain board (X-main or Y-main.) Unplug either board in succession and see if set stops clicking
FIX: Repair or replace the X or Y-main board.
--And this one, too!--
MODEL: PS42C7HD
FAULT: Maldischarge but the 100uF cap is OK.
DIAGNOSIS: N/A
FIX: Adjust Yrr/Yfr controls. Drop Vs by about 5V.
Üdv.
SEG CT2813s tip. 11AK52B6 alaplapu tv ew hibája van.
Képméret nincs meg , felül a kép vissza van gyűrődve.
A tápok jók, függ. részt végignéztem ott nem találtam hibát.
Már a TDA8177F IC-t is kicseréltem az is jó.
Van valakinek ötlete? Tabó71
