sony bravia kdl 37s4000 szellemkép? a kép alatt ott marad ez előző kép... Megoldva
Sziasztok!
A tv előéletéről nem tudok semmit, sajátnak vettem, nem kapcsolt be "a bekapcsoló gomb volt kontaktos"  örül, beüzemel , de fura a kép.
Szétszedés után a copfon volt egy szakadás, amit vezető tintával javítottam, nem változott semmi , tovább nézve a t-con on nanyon melegszik a as15-u.
Lehet e a t-con a hibás vagy kuka a kijelző?
Sony KL-50W1 Sötét kép
Sziasztok! Került ma hozzám alkatrésznek egy Sony KL-50W1 LCD PROJECTOROS gép. Meg kell hagyni hogy nincs szívem szét bontani mert nagyon szép képe van csak kicsit sötét full fényerő beállítás mellett is :( Én az izzóra gondolok hogy amiatt lehet sötét a kép de valaki erősítsen meg benne hogy valóban jó helyen keresgélek :) Találtam egy weboldalt ahol árulnak izzókat hozzá de igazából nem tudom melyiket kellene megvennem bele, de ha esetleg akadna valakinek hozzá jó állapotú izzó akkor vevő lennék rá :) Ez lenne az oldal : http://www.diybulbs.com/?11,250w-ac-hv Előre is köszönöm a segítséget.

Sony KDL-37W5500 - Blinks 8 times (Audio Error)
Hello to everyone, i have a problem with this Sony LCD Sony KDL-37W5500 Chassis EX2L MAINBOARD: 1-878-942-22 PANEL: T370HW02 Audio Amp: TAS5602 Sound System: CXA3785R-T6 main CPU: EMMA3 (under heat sink should be MB91F313APMC-GE1) Power Supply: G4, 3H267W, PSC10270F When i try to turn it on it clicks relay, blinks 1x Green Led, then it shuts down and blinks 8x Red Led. Looking at service manual it should be an Audio Error. When i try to enter Self Diagnostic Menu it just wont light up the screen. I do the sequence "I+" "5" "V-" "Power" and it powers up regularly-fault 1xgreen 8x red, black screen. From power supply i get all the voltages, except that 15V is 17.4V constant, but at the moment of powering it overshoots at 24V briefly. Also i don't get D3.3V voltage. I have 12V on regulator BD9540EFV, but enable pins 3 and 12 are held too low on 1.6V, and it need at least 2.2V to enable output, so i dont have 3.3V, only 0,7V. DVDD 3.3v is logic supply, so i dont get how CPU gets logic levels from ICs for error when there is no Logic Supply... When i measure the power for audio amplifier TAS5602DCAR it should be 13V i suppose, but it gets 17.4V, from the CON1300 pins 4 and 5. It is ok for that IC, it works on voltages until 30V, but I worry if that does not affect some other processes. Fault signal from audio amp TAS5602DCAR is on PIN19 and it is 3.3V that is HIGH and it suggests Normal Operation. On sound system IC CXA3785R-T6 pin44 the VFAULT signal is LOW 0.7V, that is too normal operation. But on audio amp pin18 TAS5602DCAR RESET is held in LOW and it does not go to HIGH to get out of the reset mode. That pin is controlled by main CPU signal X_SP_Mute. On sound system IC CXA3785R-T6 pin43 X_Protect output is LOW 0.4V that means ERROR. In datasheet it says X_PROTECTOUT outputs “L” when input voltage (SPxP/N) become under 3.0V. That is on pins 61-62 and 63-64, and if I understand right it needs to have 3+ V DC to output High Normal signal? Isnt that a bit too high to have on speakers? I measure 0V DC there, and 25mV AC. Also i can not find anywhere schematics for PSU board PSC10270F(3H267W), i need it because i think that this 15V should be around 15V not 17,4V. I did find zener diode that i think acts as a stabilizator and it measures ok, but i would replace it if i knew the markings that can not be read. All google stuff is from my posts so google wont help :) What do you think can be the main problem and solution for this ? I exclude replacing whole board I have and Audio Amp IC coming soon to replace, but i think that wont help. p.s. If anyone wants i can upload all pdfs that i have, ex2l SM, datasheets for audio ICs, datasheet for 3,3V regulator ect...
sony KV25C3 AE4 táp + sorvég tranyó
Üdv Uraim! Sony KV25C3.A szokásos táp baj + sorvég tranyó. A táp megjavítva, 2SC3997 nem volt,- egy bontott AE2F-ből /csöves volt/-kibányásztam egy BU1015-öt!! Hozzám így került és baj nélkül működött, a csövet leszámítva.Gondoltam akkor az ae4 is megy vele. Ment is 5-10 percet, aztán megint táp+ sorvég.Nem melegedet sem a táp sem a sorvég!! Kh-ra gyanakodva megjavítom,átforrasztom a sorvéget és a tápot is,/új BU1015/ tárcsakondik cserélve.Újabb próba ,ugyanaz a hiba.Időközben csak találtam 2sc3997-et, de azzal is így jártam.Lehet hogy a trafó szarakodik- pedig teljesen jól indul- vagy a sormeghajtás? Help!
