Question about Sony KV-36XBR400 36" TV

36XBR400 D board backside capacitor blues

I had the 'blinks', diagnosed it down to a bad i.c. on the D board, replaced same. (I don't know what was tougher, removing the board, or replacing the I.C.) Anyway, there is what appears to be a small capacitor in black goo on the BACK side of the D board (just opposite the I.C. I replaced). It ohms open and is outside the capacitance range of my meter(2n to 2M)...(All measured in situ!) A wise tech would replace it IMHO. What is it, if not a cap, and what voltage rating and value? Thanking anyone with a schematic in hand, in advance:

Re: 36XBR400 D board backside capacitor blues

What is the designation (the letters/numbers printed on the board right next to the part) of the part? If it is a cpacaitor then it is cesignated Cxxx, but I have a feeling you are looking at a VDR, or voltage dependant resistor that Sony loves using in their power supplies. A VDR will test completely open on an ohm meter and open on a cpaacitance meter, which means it is good. A VDR that shows resistance on an ohm meter is bad and will probably have a burned resistor (typically 10 ohms) next to it. A wise tech would NOT replace a VDR that measures open!

I have a philips plasma tv # 42pf7220a/37 has no pic. have replaced the power supply board with new one,still has red lite flashing 7 times. Have checked all capacitors and any thing that looked...

Good day!!!!

Blinks 7 times of your unit indicated bad power supply board but since you said that your power supply was now new then kindly try to reconnect all the connectors inside your tv before proceed to the advance process. May I ask if you know how to use a multimeter and soldering?...

Just add a comment for our next movement....I will do my best to help you...Thank you...

KV-36XBR400 won't turn on, "standby/stero" light

You are correct. You are right about the power supply and replacing with led hdtv. You will be happy with a Samsung led. Time to upgrade.

Picture goes black for a few seconds and comes back. This happens at random, not all the time

The main board probably has bad connections that need to be touched up with a soldering iron. Plus a few capacitors in and around the power supply.

My Tv is blinking a red light at me, 9 times, when I try to turn it on. It will not come on.


  1. Nine blinks - Replace D 6116 and D 6301 on the "G" board, do not re-solder as this will fix the problem temporary. Or Panel Module Error or Thermal Error. If it is intermittent 9 blinks, meaning sometimes the TV comes on and other times you get flashing, then change the switching regulator on the "G" board or check connections. Make sure the regulator is -12 or -13 (negative).

Green and red light flahing tv wont turn on


There is a problem inside the unit that is why you are having the blinking lights.
Blinking lights simply are symbols for you to know there is a problem with either one or more components in the unit.

Mostly, it has to do with power problems, either a bad ic problem, bad capacitor or bad power panel.
For bad ic you will have to assess all the panels in the unit to be able to detect the ic that is faulty, for bad capacitor you will have to assess all the power panel or the main board to be able to check and replace any bad capacitors, and if it is the power panel, all you have to do is to assess the power panel to see if it is burnt or have a bad capacitor, then replace the power panel or replace the capacitors.

Take care

KV-36XBD400 won't power up.

Check for bad / oxydized connector contacts, dried out / blown / inflated capacitors or bad solder contacts.

Bad solder contacts can occur on any component, not just capacitors.

These would be the first things i would have checked with the kind of malfunction you described (but the problem can also be elsewhere).

Sony KV - 36XBR400 36" keeps going to standby - blinks red x5

5 blinks is an IK balance problem. it means your picture tube is not drawing the correct current on 1 of the 3 cathodes (IK). there is a good chance the tube is bad. if you reported it while under warranty you should call the warranty company and pursue it.
