SOURCE: Sony KV-32S45 turns on at first, than blinks out, still sound

I would look for intermitent solder connections on the small horizonal driver transformer as well as other HV Componets.(HV Transformer etc.) Also solder up the Vetical output IC. These have been common causes of failures. I would not use the set until these have been checked and soldered. If you don't, a massive failure of the hoizonal circuit and powersupply will occur.
Hope this helps,

Im sorry tom have to inform you that a red light blinking is an indication that the main power supply is good BUT the sweep supply has a problem .. Most likly the high voltage transformer as well as the horizontal transistor is bad. if you have no solid state repair experience, you will not be able to fix this set on your own as we techs do gfo to school to learn the circuits in these sets and there are safety issues you have to know and equipment you have to have. sorry my freind but you going to need to call or take the set top a trained tech to trouble shoot as you cannot look at the board and see a problem. you have to troubleshoot the board and test the circuitry.

Sony KV-32S45 32" TV no power


If the power plug is fused (like in UK) check the fuse inside the plug.

Test a different power socket.

If there is no power at all, and the power cord is good, then it is a faulty power suupply board. Probably a capacitor on power board had blown.
The board must be tested and repaired by a technician.

Hi just been given a sony 50" tv but is not working how do i tell what model it is


Using a good light source, check for model information molded into the plastic rear housing. You may have to illuminate at an angle to see it clearly. Often, it is near the power cord entrance.
