Some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement.

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.

To make it a hard reset, just unplug the TV from AC mains wall socket, and re-plug it back after 15 minutes or so. This procedure will make it a hard reset. If you want to make it a system reset [Factory Reset]; you have to enter its service mode option, and select the factory reset option. If you wish to get some details; check the site linked here.

my sony bravia kdl-37m4000 have timer pc/off blinking red.

Not sure if you can see this, but I have a KDL46XBR5 and this is the self diagnostic function listed in the service manual.

Six red blinking lights, pause, six more lights may indicate a faulty backlight or a problem related to your backlight. This doesn't necessarily mean you have to replace anything, could be a ground screw is loose, or one of the many cable connectors need to be reseated while the unit is off. See attached to see if this helps.

If not, google "self diagnostic function kdl-37m4000" and see if that helps. At least this should point you in the right direction

6 times power/ standby light blink error shows problem of back light inverter board in your Sony KDL-37M4000 tv as per mentioned in related service manual.
Check back light inverter board to fix the issue.
Thanks.

The only fix is to replace the panel and that would not be cost effective. It would be cheaper to buy a new TV.

Sony Bravia... | Answered on Jul 27, 2011 | 326 views


First you will have to trouble shoot to determine if it's the power supply or the inverter board.

This problem lies in your cable remote. Try pressing the satellite or cable button on the remote given to you from your provider and try to bring up the guide again. If it doesn't work, contact tech support from your provider and have them walk you through configuring the remote.

On your Sony TV remote, press the "Input" button and make sure you select HDMI 1. Also, check to make sure you HDMI is plugged into your cable box.

Make sure you change the input that the cable is coming in on, If you was watching in HD mode then you was using an HDMI or compontet hook up.Look on tv remote for Video input button to select the componet input 1 or 2 or HDMI inputs which it is connected to. Look for a button on the remote called TV/VIDEO or INPUT
