Sony KV-27XS TD gerjed, búg a hang néha
Sziasztok! Volt osztálytársnőméké a gép, a hiba, hogy a beprogramozott adók néha jók, néha gerjed, búg, olyan, mintha nem lenne megfelelő a hangnorma. Ez most hiba, vagy tényleg a hangnorma rossz, és ha igen akkor hogy a viharba kell állítani ennél? :) Köszi! Üdv: Pityesz
Sony kv-m19d nincs stand by....
Üdv! e készülék szívat, egyszer van készenlét egyszer nincs, ha van egy pillanatra indul a sor, nagyfesz de le is áll szinte azonnal, str54041-et, 22u, 560k, a táp primer oldalán cseréltem, forrasztásokat átnéztem, szerintem a készenléthez szükséges 7v szekunder oldali fesz hiányzik...ebben szeretnék tanácsot kérni, előre is köszönöm!
Sony KDL-37EX402 the TV in dead, no LED, motherboard problem.
Hello

The TV does not show any sign of life , I started the troubleshoot as this , no power Led, no reaction when pressing the power button.

I checked the Power coming out from the power supply, the 3.3V_standby is correct and steady, then I checked the 1.2V_standby produced by IC6001 which Is good as well.

So I decided to control the main IC , IC4000 , he does not output any oscillation on the Xtal, Then I am now bloacked there.

The schematic is downloadable on this  website , the schema is weird because the processor is not represented with any Xtal output, but obviously it has one.

Thanks you for your hint and help.
