The main power supply or the scan circuits are staring to fail. Considering the cost of service for this type of fault, I would consider to start shopping for a new set.

Hi? My Sony Projection T.V model KP-FX432M91 is taking time to power on and once it has powered on it work fine.what might be the problem?


Power button may need to be replaced. Try turning on via remote.

Some TVs need to warm up before coming on. Hitting the power button several times may in all actuality be Turing it off and on.

I have a Sony FD Trinitron Wega (KV-32HS510). When I attempt to turn the tv on by pressing the power button on the remote or on the tv, the standby light comes on and I hear two clicks but tv don't...


The primary power supply is good,maybe the horizontal output transistor is deffective thats why there is no high voltage supply in the picture tube because theflyback have no supply voltage and oscilation.So check the harizontal output transistor and replace if deffective.

The TV keeps going into standby mode , comes back to proper picture and with-in 15-20 seconds goes back into standby mode. It happens continueously.


Hi,

May I know if the standby led light at the front panel is blinking, if so please count how many times it will flash to determine the error code? If not follow the steps below.

In standby mode press the button of the remote control in sequence, " Display ", " Channel 5 ", " Vol (-) ", " Power ". Self diagnosis screen will displays. Le me know the result.

Sony FD Trinitron WEGA Tv KV32FQ86E two flashing led


The high voltage power supply is going bad on both units.. Pretty soon, it won't power up at all. For a fact.
Don't try to replace the power supplies, TV's are too cheap.

Sony wega trinitron won't turn on


  • 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.
  • and some times the eprom ic is fulty ...
  • try to unplug your tv from the main power for 5 hours then press the power button and keep pressing for 7 seconds then release ,if this do not work ,you should take your tv to a qualified person

    Push display - 5 - vol + or - then power. Clear CH setup if there and if the right numbers are not zero the push 8 then enter, that will clear the numbers, like reset. IF unit no workie the start up that way and any zero with numbers are what the units problems are.

    Sony Trinitron TV takes multiple manual clicks to turn on.


    If you mean the actual mains switch needs multiple cycles, it could be faulty.. does anything, say a power indicator, come on when the TV doesn't?
    If the actual switch is OK, then you probably have a fault in the power supply section... often faulty electrolytic capacitors. U need service.
