I have a Sony KD-34XBR960 and the standby light blinks twice and makes a click noise and a bang sounds off in the back of the TV and then it repeats its self , the TV does not turn on .
- Two blinks - B+ over current protection (OCP), unit goes to the standby mode then displays the 2 blink fault. Could be a short in the power supply of any of the circuits.

RED FLASH AND TV URNS OFF
- Unit is dead, No blinks - Problem in the standby power section. Might check fuse, R607, Q601, IC601, R612 and VDR601 (should show open).
- Continuous blink once a second, no pausing - No reply from the jungle IC301 (data bus is busy, shorted to ground, or held high), IK video path is defective.
- One blink - not used for the self-diagnosis
- Two blinks - B+ over current protection (OCP), unit goes to the standby mode then displays the 2 blink fault. Could be a short in the power supply of any of the circuits.
- Three blinks - B+ over voltage protection (OVP), unit goes to the standby mode then displays the 3 blink fault. This is also a problem in the power supply circuit, check T603 and R672.
- Four blinks - No vertical Deflection (V STOP), Screen goes to a single horizontal line then the video signal muted. Check IC1509, Q1505
- Five blinks - AKB circuit (automatic kine bias), the timer/standby indicator blinks for about 30 seconds then goes to the self-diagnosis function. Something is wrong with the video. Check video out, Q705, 732, 761 and other components on the C board, also check Q218, 219, 220 on the A board. In addition, unit could be in IK blanking, try turning up screen slightly.
- 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.
- Eight blinks - Problem with the audio (AUDIO), unit goes to standby and blinks the self-diagnosis code. Check IC406audio amp, PS401, and 402. On some projection models of Sony TV sets, this code means that T8005 (flyback transformer), or the associative components in the high voltage circuits are defective on the D board.
- Nine blinks - Replace D 6116 and D 6301 on the "G" board, do not resolder 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 (negitive).
- Ten blinks - Check Q8014 and Q8013 for shorts, leakage, or bad solder connections on the " D" board. If the transistors are bad, check R8051 and IC8005, also on the "D" board.

Sony kd-34xbr960 will not turn
Good day!
Unfortunately,the board/chassis is not available at any store online....only spare parts!!
but if you want to fix your problem on your own I'm here to teach you how to do that..
- Open the back cover of your TV..
- check the B+ supply (it is usually located at the 3rd pin of ply-back.
- if you don't have B+ the problem could be on the power supply section..check the possible open resistor and shorted diode and transistor..
- If you have B+ supply but it cut off,,please try to hang the connection of it then try to check again if it is stable when it hang the problem is the ply-back transformer..please replied it with the same type and part #..
- If you have voltage in B+ and the ply-back is not switch..The problem could be the Jungle I.C..please replaced it..
That is the possible trouble on your TV..please try to do that..
You have a better chances if you have failing capacitors on the chassis..
Look the actual image of it..If looks like leak/bulged on the top and bottom and sometimes have a oil on the based...please replaced it with the same value,type and ratings (uf)microfarad..
hope it helps....thank you..

Sony KD-34XBR960 has no power;
The problem is in the power supply, the most common cause is an open fuse and open capacitors, if the set is more than 10 years old consideration should given in replacing the tv especially if a professional gets involved.

Color of green in upper
Hello; You probably have a CRT type set. Something has magnetized your CRT/Picture tube. The set has a built in degaussing system that will only work when you turn on the set when it is COLD ONLY. If after several cycles of turning on the COLD set and the green color hasn't gone, the circuit in the set for doing this has failed, OR you have the set near strong magnets, such as speakers. PUT ALL speakers at least 4 feet from the set and go through these off on COLD cycles. The deflection yoke on the picture tube could have moved due to Sony using crappy adhesives to hold the yoke positioning wedges in place. I am so glad to be done with Sony!!!!! John

How to find a diagram number
You can download a pdf copy of the service manual
here. It's in 10 parts and in rar format. You will need
WinRAR or
7-Zip to uncompress and reassemble the parts, and Adobe Reader to open the result.

Sony KD-34XBR960....problem is that screen
This tv have two power ICS left side of the FBT-The Flyback Transformer.The big black block of plastic with a red wire with a cap hook to a CRT(tv tube).Replaced those 2 power ICS,tv will solved this LED power light flashing,tv will have stable power again,tv will work.

Sony KD-34xbr960 will not turn
Hi
Thanks for using FixYa. If its flashing
continuously and you are unable to count the no# of blinks then the issue is
with the bulb going bad and should be replaced. Please do accept the solution
if the issue is resolved or post a comment for further assistance.
Thanks

I have a Sony KD-34XBR960 that sound like it is
phillips has the same problem but if your tv actually turns on it could be a short or just a fuse sonys a better tv than phillips should be an easy fix call a repir guy going price for that problem is 75.00 dont pay any more than that. the economy is bad everyone needs the work be smart. make sure if you say yes to the work that the repair guy will waive the consultaion cost of usually 35 to 75 dollars, if you chose to have the work done.

Tv wont turn on....
Hi
Thanks for using FixYa. It you are
away for a long period then turn it off to avoid any damage to the TV. Resolder
the flyback transformer (FBT) as this transfer the power to the TV. A bad
switch, power supply failure or a blown fuse as we know fuses blow due to high
current event, possibly a shorted component on one of the low voltage rails. The
shutdown circuit could be activated. The problem most likely will be that a
component has become thermally sensitive or some capacitors that have become
puffy or bloated and needs to be replaced. From what you have described it
seems the issue is with the power board or the main board we’ll need to check
few things. When you open the unit up; take a look at the power board-the board
where, the power cords/plugs goes into. You might see some filter capacitors a
little bulged up in the top-If this is the case-this is your defective part(you
can try to replace them-but some soldering equipment is needed). If not, then
probably the main board has gone bad. This is the other board-where all the
inputs are going into. Also check the Backlight Inverter Board if the sound is
coming fine from the TV however as it’s shutting off so it should be either the
power board or the main board. All this is only recommended if you have
electrical expertise and know how to solder/re-solder components.
Please do rate the solution if the issue is
resolved or else revert for further assistance.
Thanks

Hi
Thanks for using FixYa. Blinking Red Standby light indicates a issue with the internal circuitry of the TV, as you have not mentioned the no. of blinks so please check this:
- Unit is dead, No blinks - Problem in the standby power section. Might check fuse, R607, Q601, IC601, R612 and VDR601 (should show open).
- Continuous blink once a second, no pausing - No reply from the jungle IC301 (data bus is busy, shorted to ground, or held high), IK video path is defective.
