Press the power button in and TV tries to come on but fails


Common problem with this model is the line output transformer.

No power output or display.green standby light flashes.


Sounds like either a blown mainpower fuse or the thermal fuse for the power transformer. If the protect circuit was kicking in, the display would light up, but then turn off with a red blinking light. the green light with no display means the transformer is not getting power.

Turn on tv no picture no sound standby light starts green changes to flashing red


the number of red light flashes indicate where the fault lies...sony error codes are easy enough to find if you google the model with the number of flashes.hope this helps somewhat as you dont say how many blinks!!
regards,steve.
ps.line output transformer failure rates are quite high on these sets,usually resulting in two red blinks-pause-two red blinks-pause etc...

Tv comes on, green light flashes several times, get the "digital television" shown at botton left corner, then flashing green light stops, tv turns off and red constant "stand by" light comes back on. TV...


common problem with that model is the backlight inverter, 1 or more of the six transformers may be bad.also check for bad capacitors.the tedious way to check is unplug each and plug in each one at a time but unplug the power from the tv each time you check one or you will get a nice jolt. the one that doesnt light the lamp is bad.or take each transformer off and check the primary and secondary coils if you find one open coil. the transformers cost between $8 and $20 each.it has a substitute part.

My tv wont turn on the green button flashes to red


Power supply aka high-voltage transformer is likely bad. It can be tested with a voltmeter. Make sure the voltmeter reads the same DC Voltage output as the label on back of tv does.

60" Sony SXRD that won't turn on


Sounds like the line output transformer (flyback transformer) has gone out.Depending on how old the TV is will depend on if it is worth fixing

Tv wont turn on and has a high pitched sound while plugged in


your flyback transformer and driver circuit are operating, but the horiz. output transistor that needs to be in circuit w/horiz output transformer is open and can't amplify the signal needed for the flyback xfmr

Television when turned on: light goes to green then flashes twice. green light goes out and red light comes on. tv will not come on.


If the Red Light Blinks twice and goes out, the TV is in Protection Mode. There are 6 voltage outputs to the lamps around the screen. If one of those outputs is missing the TV will sense that there's a problem and refuse to turn on. The predominant failure in this model are the output transformers on the Inverter board. A properly trained technician can measure the windings on each transformer and look for an open circuit, if one is found, replace that Transformer. i was given one of these sets from a friend and I replaced an output transformer ($11 w/shipping) and I now have a fully functional TV/DVD Combo. Also verify that all of the connecting cables internally are properly seated, there have been reports or the ribbon cables from the Power supply board to the main board above it not being fully inserted and it also prevented the TV from turning on. A word of caution. There are VERY High Voltages on the inverter circuit board, only persons with proper training and knowledge should attempt this repair.

Red power light keeps blinking and wont come on


The first thing to try is to unplug the unit from the wall for about 15 minutes,if this does not work you will need the assistance of a servicer to diagnose the problem,if you are familiar with tv service you can check the horizontal output transistor for a short,sometimes it fails for no reason and other times it goes bad along with the horizontal output transformer also know as flyback.Be careful if you decide to check this yourself.
