Sony KDL-40W4500 képernyő jobbról balra elsötétedik
Hello, ki látta pont ezt hibát? Itt állok megfürödve, de a neten ismerik. Ez a link PONTOSAN ugyanazt mutatja: Hol keressem?
Sony KV-29X1E /BE-3D/ jobb csatorna gerjed
Tisztelt Kollégák! A fenti készülék jobb csatornája gerjed, kb. 2 kHz-es fütyülés jelentkezik. TV és AV üzemmódban egyaránt. Az "A" board-on lévő IC202 MSP3410B-PS-F7 multi hag proc. kimenetén "57" már gerjedés van. A proc. környéke ellenőrizve, hibát nem találtam. Az IC hibájára gondolok. Volt valakinek hasonló problémája? Van valakinek javaslata, vagy ötlete ezzel kapcsolatban? A HQ-nál,Sini-nél sincs lehetőség rendelni. Köszönök minden segítséget. Üdv: K. Gyuri
SONY trinitron kv-x2551k eltünik a piros szin. Megoldva
Szevasztok megint a segitségeteket kérném eme géppel kapcsolatban,az a bibije hogy kb 10 perc müködés után eltünik a piros szin belőle.Elsőre azt gondoltam a videó erősitő vacakol,megcseréltem a két csatornán a tranzisztorokat,de a hiba nemment át,igy kezdtem méregetni.A szinmodul tda4650 dekóder, tda 4580 illetve tda4660as müvonalra épült,szkóppal kezdtem visza követni a piros szin vonalát,és azt vettem észre mikor jól müködik akkor a tda4580 egyes lábán 5.25 volt van, mikor rosz ez leesik 3.2re.Kicseréltem a 4580 nas második lábán lévő220nanós kondit ,semmi változás,visza követtem a jelet egészen a 4650es -RY kimeneteléig de ottnem láttam változást mikor rosz ,sem pediglen a4660 as ki illetve bemenetén.A tda4650es RY BY kimenetén a kondik cserélve,illetve a tda4660as10-14 lábáról elmenő kondik szintén cserélve,de semmi nem változik,hol 5 hol 10 perc után eltünik a piros szin. Ha tudnátok valamit mondani hogy hogyan tovább cseréljem a 4580 ast vagy van valami tipushiba ezeknél a tv-k nél.
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...
