Sony model KV32S42 stuck in standby mode.  I have tried to reset the power by unplugging it, even over night, but still stuck in standby.  Can anyone help?

my sony tv is also stuck in standbt mode what can i do to get the picture back.

When you attempt to turn on the set, the standby light should end up blinking a number of times, pause then repeat the blinking. Please count the number of blinks and post here along with the model number of the set. With that information we will be able to guide you to a solution. Dan

from pat johnson

modle #  KV32HS500

blinks 6 times, pause blinks 6 times and so on.

6 blinks indicates a problem with the 5v line on the A,B.or M,boards, also could be a problem with IC504,also check the Horizontal driver transformer for ring cracks around the terminals that can cause that too.

To quote Sony:

Low HV Shutdown:
On the D Board.
Check IC8004/pin 7 should be 7.4v.
Check IC8006/pin 2 should be 2.5v if lower will trigger shutdown by causing pin 1 to turn on.
Check IC8006/pin 3 reference voltage 2.2v.
IC8006/pin 1 normally at 0v. If high  turns D5007 ON which turns the latch circuit Q6532,
Q6530, and Q6527 ON and turns the AC relay RY6501 OFF.

NOTE: 6 blinks also can be Low B+ protection.

Unregulated 7.5 v from the power supply to 5v reg IC504 on the A Board. 5v to M Board Q2314 
to CPU IC2300/pin 43. If 5v missing set will shutdown with 6 blinks.

Our Sony TV (Model Trinitron KV-27V42) has gone to standby mode since yesterday. The Standby/Timer light blinks four times, stops and blinks again. The TV does not start. Could somebody help to resolve this problem? Cry Thanks.

I have a Sony KDF55WF655 and the indicator light blinks 6 times, pauses, blinks 6 times and continues. When the screen went black, I still had sound. This tv is only 2 years old, and I don't have a service manual... can anyone help me... id greatly appreciate it

6 blinks = overheat condition. This can be for a number of reasons. Check for proper air flow first. Otherwise check the thermal fuse. This will go open if the set gets too hot shutting down the set before further damage. A bad Q6007 on the G2 board which controls the fan speed could cause this as well. If either of these are the problem, the repair should be a reasonable cost as the parts are less than $15 or so. Dan

How do you replace the thermal fuse, and where do you buy them? Can I replace it, or do I need to have a technician do it                                                                              /

sony triniton xbr36 blinks seven times, pause, seven times, etc. any ideas appreciated

September 22, 2008 2:28 PM

My Sony Triniton blinks 5 times in stadby/timer mode. If you un plug it it sounds like it is powering on , but does not. :-(

September 25, 2008 6:45 PM

I have this problem as well. Except my standby light blinks continuosly. I hear the click when I power it on but nothing else happens after. Screen remains black. Sony Trinitron KV-35S24.

I found an article from Sept 24th 2008 where a guy in canada is working on this problem with his KV-35S26. Have asked him to post what he did to fix it when he does fix it.

My SONY KV-36FV300 stand by light blinks twice pause blinks twice etc. Any idea on problem and cost to have repaired

Here are the blinking codes I found online here. I've also found that you can order a complete G Board (power supply) part no. A1316399A for the KV-35S42 at www.tritronicsinc.com for $116.25. Something to think about if you KNOW the problem is on that board.

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. I have found no such part in the Service Manual for KV-35S42.

One blink - not used for the self-diagnosis

Two blinks - B+ over current protection (OCP), the unit goes into standby mode then displays the 2 blink fault. This could be a short in the power supply of any of the circuits.

Three blinks - B+ over voltage protection (OVP), the unit goes into 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 IC406 audio amp, PS401, and 402. On some projection models of Sony TV sets, this code means that T8005 (fly back 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. This could also be a 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).

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.

Thank you Kevin. I will relay this to the TV repair dude I have been waiting 5 days to hear from.

October 4, 2008 11:08 PM

you can also have the G board rebuilt at ptcorp.com for less money. Good luck
