On this TV there are 3 boards, 1) power supply board, 2) Video and input board and 3) t con board. The power supply board powers the video and input board. The video and input board powers the T con board. With the tv in black screen mode check the voltages as outlined on the diagram next to the two white connectors on the brown board that feed the video and input board. If all the voltages are correct when the screen is black, then the problem is either the video input board or the t con. If you see the Vizio logo at start up, my guess is that the video and input board is bad. Power board is brown, video and input board is green and t con is under the metal plate at the bottom of the screen.

Fault to the main power supply regulator section. Either it will be a separate board, or the part of main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts.

It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.

Testimonial: "thanks for your help. I intended to replace the power board, but I'm not sure if it's bad. Actually, I checked it, everything looks good except one pin, it is broken. but my concern is why it works sometimes."

You may have a bad ballast. Check to see if your lamp is lighting up through the back of your T.V. prior to the picture coming on. If it has done this since you bought it, it's probably the just the way the T.V. was designed. If it still comes on every time, it could also be a power supply issue, but nothing to stress about.

Sony kv35s66: No picture, just sound and red blinking


This should be a quick fix. Try resoldering the vertical IC. This is a small flat IC attached to a heat sink with about 11 pins. It should be marked LA7837 or something similar. That should resolve the problem.

Keep us posted.
