Sony Trinitron TV ,model KV R21M1 sorvégfok melegedés!
Üdvözletem a Mestereknek!Kaptam ajándékba a fent nevezett tv-t ,nemrég volt javitva , "lapos tv" váltotta fel a helyét az eredeti tulajdonosánál!Sajnos nem sokáig örülhettem neki mert 5 percnyi filmnézés után a vizszintes képméret egyszer csak lecsökkent, hirtelen ,összeugrott a kép ,majd eltünt teljesen ,és felszált az üzemi füst.A tv alaplapján csak a 1-653-363-22 számsort találtam . Kutakodtam a neten és azt találtam hogy G3 saszira épül fel ,ilyen rajzot viszont nem találtam ,igy a Tanyán lévö G3E rajz alapján áltam neki a javitásnak. A sorvégfokozatban BU 2520 DX tranzisztor volt nemrég beépitve ez zárlatos lett,a rajzon 2SD1878-CA van feltüntetve.Mivel ilyen tipusu tranzisztorom nem volt BUH 515 D tipust tettem a helyére,mielött bekapcsoltam volna ellenöriztem a C801-33mikro/160 volt,R806,R803,C802,R811,R808,R809 pozicioban levó alkatrészeket .Bekapcsolva a tv normálisan müködik ,kép ,hang,szin rendben.Bekapcsolás pillanatátol mértem a sorvégtranzisztor hütöborgáján a hömérsékletet,1 órai müködés után a hömérséklet 54 fok,ennél jobban nem emelkedik.Az lenne a kérdésem hogy ez a höfok megengedhetö e hosszu távon ? A sorvégfokozatot meghajtó driver tranzisztor kollektorán 100 pp nagyságu jelet mértem, rajz szerint viszont 170 pp kellene ..Nem szeretném ha elfüstölne ezért megvárom a véleményeiteket ezzel kapcsolatban ,és elöre is köszönöm üdv dddemeter! .
Sony KV-21T1D chassis BE-4A táp
Sziasztok. Egy ilyen táppal küzdök. Tünetek: Bekapcsolás után felszisszen, aztán a tápled elkezd villogni. 6 rövid, szünet. A service manual (30.old) alapján ez overvoltage/overcurrent protection. TápIC: STRS5706. Feltöltöttem a táprajzot és a service manualt is. Az itt leírtak alapján IC csere, esetleg LOPTx csere. Amit eddig elkövettem/tapasztaltam: C608 10µ 50 cserélve (igaz nem low esr-re, mert nem találtam itthon) C620 100µ 160v cserélve 60W-os izzóval nem indul. 40W-ossal második ciccenésre indul és 137V van a B+ -on. Az R607-en 45,3mV van. A Sens bemeneten 32V-ot mérek. Szerintetek? Vegyem az IC-t? Sanyika
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 KDL-xxU2xxx (SE1 Chassis) Service Tip - Blinking 4 Times "Panel Error"
KDL-26U2000, 32U2000, 40U2000... TV Shuts off after "some time", LED blinking 4 times ( Panel Error ). This is caused by SMD Fuse F003 on the Inverter ( 0,3A or 0.5A according to size of TV ) going Ohms instead of conducting perfectly. Change this to a new one. Fuse is located just beside the power cable from the PSU... Fault off course relates to all models with the same inverter board ( KLS400W2 ) Sincerely, Lars / Sound2Vision Az angolul nem tudóknak: KDL-26U2000, 32U2000, 40U2000 ... TV kikapcsolása "után egy ideig", LED villog 4-szer (Panel hiba). Ezt az okozza, hogy az inverter SMD biztosíték F003 megnyúlik (Ohm értéke lesz 0 helyett) (0,3 A vagy 0,5 a TV méret szerint) . Új alkatrész cseréjével megjavul. A biztosíték a tápegység hálózati kábele mellett van ... Hiba természetesen vonatkozik minden modellre, ami ugyanazzal a inverter lappal készült (KLS400W2) Tisztelettel, Lars / Sound2Vision Kalex
