Hello- Sony TV model KV30HS420. Turns off after a few seconds. Flashes 6 or 7 times, repeat. Have found a few threads on subject. Most common part replaced seems to be a semiconductor, Sony part# MCZ3001D. Am I on the right track? Any info appreciated. -Thanks- ED

Hi
- 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.
Thanks for using FixYa. Blinking light indicates an issue with the internal circuitry of the TV, as you have mentioned the no. of blinks to be six or seven then please check this:
Please do accept the solution if the issue is resolved or else revert for further assistance.

Ed I am also not here to make you learn the codes. To repair the set you'll need to open the back off the TV and check for the Jungle IC, IC 206. Also you'll need to check the Horizontal Circuit. All this is only recommended if you have electrical expertise and know how to solder/re-solder components. If you get this done by a professional then the estimated cost of repair should be around $200-$300 depending on the parts that are be replaced. Please do accept the solution if the issue is resolved or else revert for further assistance.
Thanks
