Sony 32Fq70 e Red Blink

[robbynaish]

Ciao a tutti,

ieri sera è passato a vita migliore il mio amato Sony. Usato molto poco, ma..... pare andato.

Spiego la problematica.

Erano 2-3 gg che ogni tanto, ma raramente, vedevo come delle scariche orizzontali sul video, verso l'alto dell'immagine.

Ieri sera appena acceso, lo ha rifatto.... e si è spento.

Ho provato a tenerlo spento, con il pulsante, tutta la notte... ma nulla.

QUando accendo, si sente l'audio per qlc secondo, poi fa otto lampeggi il led rosso, e poi si spenge anche lui.

Cercando in rete ho trovato questo, ma qui dice che 8 blink sarebbe un problema audio, quindi non so se qs tabella è valida per tutti i Sony dato che a me l'audio si sente

Sony TV Blinking Codes & What It Means When the Standby/Timer Light Flashes
Sony problem:Unit is dead, No blinks - Problem in the standby power section. Might check fuse, R607, Q601, IC601, R612 and VDR601 (should show open).

Continuous blink once a second, no pausing - No reply from the jungle IC301 (data bus is busy, shorted to ground, or held high), IK video path is defective.


One blink - not used for the self-diagnosis


Two blinks - B+ over current protection (OCP), unit goes to the standby mode then displays the 2 blink fault. Could be a short in the power supply of any of the circuits.


Three blinks - B+ over voltage protection (OVP), unit goes to the standby mode then displays the 3 blink fault. This is also a problem in the power supply circuit, check T603 and R672.


Four blinks - No vertical Deflection (V STOP), Screen goes to a single horizontal line then the video signal muted. Check IC1509, Q1505


Five blinks - AKB circuit (automatic kine bias), the timer/standby indicator blinks for about 30 seconds then goes to the self-diagnosis function. Something is wrong with the video. Check video out, Q705, 732, 761 and other components on the Cboard, also check Q218, 219, 220 on the A board. In addition, unit could be in IK blanking, try turning up screen slightly.


Six blinks - No Horizontal (H STOP), no raster, goes to the blinking self-diagnosis function immediately. Check C515 & 516 and the jungle IC, IC206.


Seven blinks - High voltage shutdown. The high voltage has exceeded 33k and the unit goes immediately into safety shutdown. Check power supply regulation and horizontal circuits.


Eight blinks - Problem with the audio (AUDIO), unit goes to standby and blinks the self-diagnosis code. Check IC406 audio amp, PS401, and 402. On some projection models of Sony TV sets, this code means that T8005 (flyback transformer), or the associative components in the high voltage circuits are defective on the D board.


Nine blinks - Panel Module Error or Thermal Error. If it is intermittent 9 blinks, meaning sometimes the TV comes on and other times you get flashing, then change the switching regulator. Make sure the part number is -12 or -13.

Intermittent problems? This is a great feature. You can also bring up these fault codes on-screen to see a list of the problem numbers with the abbreviation of the problem and the number of times this problem has occurred. This is slightly different than entering the service mode. To see the diagnostic screen, press the following buttons: Display, Channel, 5, volume Minus, ( not plus ) then Power. This brings up a screen with a list of the problems and number of times they have occurred. Each of the problems named, are abbreviated as, "OCP", "OVP", "V STOP", ETC. We have repeated them in parentheses in the text for the "Blinks" described above so you can correlate between the diagnostic screen and the blink codes.

Now that you know about these self-diagnostics, how do you use them? Say that you have a set with a black screen. You see that the LED is blinking four times. This would tell you that you have no vertical sweep, which is why the video is muted. If it was blinking 6 times, you would know that you have a horizontal fault. It's not a sure cure..


IMPORTANT: After you repair the unit, you MUST clear the values on this diagnostic screen. These codes do not reset themselves after the fault is corrected, so if you don't clear them, you'll be seeing "old" fault codes the next time you enter this screen. Clearing is done by going into the service mode (display, channel, 5, volume plus, then power ). Press 8 and Enter, which returns everything to the factory preset condition.

Che dite? Io ci tengo troppo a qs bellissimo TV, non vorrei che la riparazione fosse troppo costosa.

Grazie a tutti

il led rosso lampeggia sempre nei tv sony, quando ci sono guasti o malfunzionamenti.


perdita di impostazioni di fabbrica causati da' sbalzi di tensione, possono causare anomalie nel funzionamento.

devi richiedere assistenza per la tv , qualcosa e' partito, non sara' costoso da' riparare, dipende dall'onesta' del centro assistenza.

bye

Difficilmente servirà, ma io oltre a spegnere col pulsante farei il tentativo di staccare la spina per un pò.

Si, lo avevo proavt... nada.

Cmq, il tecnico mi ha detto che bisogna sostituire l'orizzontale (come avevo intuito) e anche la scheda che sta sotto (cosi ha detto) cosi per stare piu tranquilli.



Con assistenza a casa, mi ha chiesto 150 euro!!! Che dite, Si è allargato?


Grazie
