TV SONY KV-HA21M80 BG2T

Good day;
i don't speak english
Please send me solution for repair my tv sony model KV-HA21M80 BG2T.
Symptoms: The red led in front pannel flashes 4 times after powering the tv. I have changed the vertical ic an5522 and controlled +13V and -13V
Bonjour;
Prière m'assister à réparer ce tv qui présente les symptômes suivants:
A la mise sous tension du tv, le téléviseur démarre ainsi que le transformateur de sortie lignes (FBT). Les tensions sont correctes à tous les niveaux. Tout de suite après quelques secondes le 9 Volts disparaît, le FBT cesse de fonctionner, et la led rouge commence à clignoter cycliquement pendant 4 fois. En forçant la présence du 9 volts, l'écran s'illumine avec des retours lignes en l'absence de tout signal vidéo.

Thank you.
Merci pour votre généreuse compréhension et salutations cordiales.

Thanks for reply and nice to know that you are in Algeria.

You need to pay attention on Screen Volts as wrong G2 (screen volts) can be cause of 4 times blinks as you already replaced vertical out put IC.

You can download service manual of KV-HA21M80 from HERE and it is free. Download all 3 parts of file and use WinRaR to unzip it. You will have complete manual in pdf format.

Good luck.

Sony tv model KV-HA21M80 is having problem front stand by L.E.D is blinking 4 times and stopping


These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices.

The 4 blinks indicate the problem circuit, but I need the model number to give you the specifics. The category you entered is KV-36fs120 which is a 36 inch set. Please update this with the model number. It should be on the back.
Thanks,
