Question about Sony KV-32V36 32" TV

1 Answer

Powered itself off and will not turn back on.

My wife was watching the tv when it powered down on it's own. It would not
turn back on via remote or top touch pad. The surge protector didn't fault out, as the other components plugged into it remained powered up. I looked on the back side of the tv for a fuse holder, but did not see one. I would like to know if there is a fuse inside the tv that may have blown, or if it finally bit the dust. Any help would be greatly appreciated.

    The same thing happened to our 32V36 yesterday. If there are no LED lights blinking at the bottom, then chances are the power supply is fried. I guess this is a common problem with older Sony's. If you have LED's blinking, count the number of blinks and call a certified repair shop to find out what the code means. My local shop guestimates the cost of installing a new power supply will be around $250. Must be all labor, because I've seen kits on-line for like $7! Good luck. Lift with your legs.

I have not worked on this model for a very long time. But, if you look
down the centre of the main board, I believe that there are a number of
voltage regulators in a row that are heatsinked to the top frame, using
a metal bar, or something like that. Re-solder all the pins on these.
Also resolder very well, the leads of the horiz line drive transformer,
that drives the HOT (horizontal output transistor). This is the small
transformer after the horiz line drive pre-amp stage that is before the
HOT.

Because you say that the set is going back to Input 1, this means that
something is doing a full reset. This means that the uPC is loosing its
supply, and thus re-setting. If this set is properly turned off and
back on again, it should come back to where it last was. In some models
of the Sony, there is a separate standby supply for the uPC. In your
model, I think that that the standby supply is part of the main power
supply. If this is so, this means that something is putting the complete
power supply in to protect, or it in itself is failing.

Also do an ESR test on all the electrolytic capacitors in the power
supply, the horizontal output stage, CRT board, and the vertical
deflection amp. I've seen problems with these in all of these areas,
especialy when these sets were getting old.

This is what I can remember that I used to do with these sets. If it
beyond this, then you will have a challenging job to find the fault. It
is able to be found, but you will need a lot of experience, and the
proper setup with the proper service information to find it.

SOURCE: TV will not switch on

this can be caused from numerous reasons, I will specift only the most common ones which doesn't require professional skills to deal with. The "easy" initial technical troubleshooting that can be performed, without a schematic and without a service manual, is using your DMM to make voltage readings and test components, also do a careful visual inspection and make not of any faulty or cracked solder connections around the high heat producing components and other pertinent details. Given the symptoms you reported, it should be obvious that the areas of initial troubleshooting interest in the television circuitry are the main PS, B+ regulation, and B+ distribution, standby B+ , the HV and HOT area.... also pay attention to the and flyback derived B+ circuitry and components.

You Probably have a bad flyback transformer(The HI VOLTAGE) and a defective horizontal output transistor. I you have training in the tv repair , then you can go to http://www.partstore.com and getthese parts. they arte soldered in so your gonna have to know how to solder and unsolder as well. You should also know all the safety issues regarding the HI voltage in these sets. If you dont I highly advise that you take this set to a pro for repair as theres hi voltage inside these sets even when they are unplugged. Good Luck

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 Cboard, also check Q218, 219, 220 on the A board. In addition, unit could be in IK blanking.

Hi, tubes getting tired, band-aid fix you can do is remove back of set and turn up(clockwise) the screen control( small black plastic control mounted on side of flyback transformer, do not turn the knob marked focus) until you see a whole bunch of white lines across the screen, then turn same control counter-clockwise until all the lines go away, try several different channels to be sure all the retrace lines are gone, you`ll get up to 1 year more use out of it, than she`s done, good luck, BMW Rider

I have a Mitsubishi 73"


i would suspect your control buttons on your front panel on the set have become shorted. specifically the volume buttom down. This is freezing you control functions. like someone is holding the volume down button all the time. or intermitantly. this cuircit board is on front of the set. I have seen this problem a few times at the shop. The common repair is to replace that button assembly cuircit board. I believe the last time it cost the customer around 85 dollars, but like all things depends on the part and the technician that puts it in.

I have a WD62825, it lost power while watching. There is power at the plug in.


Is the grreen light on?..or can be switched on via remote? Plug it out then back in. Green light flashing? If so...you have lost input signal or the tv has reset itself to another input (non functioning). Use Remote to set input (via Net Command) to functioning signal. If the Green light NEVER comes on...it may be major system failure. Be sure remote is set to "TV"

Can't change from HDMI2 back to HDMI1


You need to change via tv selections option for tv, this should be possible by selecting the source for tv feed. This should give various options to select hdmi11, hdmi12, scart1 ect. If remote not working to change look on the tv itself for the control buttons, normally on the back to 1 side (rh from front) then pressing the correct button. If this does not work try turning power off to tv for a couple of minutes and then turning back on. Hope this helps.

The TV is on protect mode.

Try first leaving the TV power cord unplugged for some times, let say one hour or so.

Also ensure that the fault is not coming from a faulty receiver box sending bad signal, check if you get same problem with no receiver box or dvd connected.

If that does not work, and you keep having a flashing led on front of the TV, and tv turning off by itself after a while, that indicates a fault condition.

The flashing light indicates a diagnostic state called protection.
When the TV goes on protection there are only two possible reasons.

1The internal circuits are jammed because of electrostatic charges accumulating on capacitors, or because of a wrong voltage read by the main chip on your monitor controller board. this started the protection circuit.

2 The protection circuit detected a wrong voltage or abroken contact, identified an internal fault and kicked in , startingthe flashing light.


If you are in situation one, then theTV will reset just unplugging power cord for one or two hours,sometimes even minutes.

If you are in situation 2 , then there is an internal fault.

Common faults that can occur are a blown capacitor on power board, a convergence IC has blown, or a fault on Digital board.

Check also the video cable or any external connection cable, if the cable is shorting, or the connector is bad, you can get same flashing state because of the video cable.


If under warranty contact the manufacturer ringing the number on the user manual

If you want to repair at your own expenses, just locate any good qualified repairer.

Try resetting the TV by holding down the "up" button on the remote (with the TV powered on) and then, while you hold down the up button on the remote, hit the power button on the TV. This should do a "factory reset" which will wipe all settings in the TV. There is no reason why the TV should not "remember the last input it was on when it was ;last turned off. Also be sure that the TV is not plugged into a switched AC outlet, like the outlet on the back of the cable bix. The TV should be plugged into an output that receives power at all times.
