hiiiiiii here shivam
i want to tell you that that same problem is occuring my computer but now it is fixed
but your problem is of tv don't worry is this is help full to you--

this problem is common on this model. your vertical output circuit has gone bad. but i am sorry to say that a repair cost is to much for a tv this age. a cost would range 100-150. i say invest this into a newer tv. this model was good for 10-12 years and you have got better than that.
good luck :)
let me know if you need more info?

No, the PS has nothing to do with that - the standby light blinks to signal an internal component failure and a bad source connection can't cause that. Since the light is steady at start it means that the power source starts normally but the process doesn't end correctly: the defect is located in either the mainboard (the processor has failed) or the inverter for the backlighting tubes has failed.
To identify which you will need to open the tv and test the voltages on the power source board starting with the output line for the inverter; after that the voltages for the mainboard - you will need at least a good multimeter and experience in electronics repair. If you don't have both then unplug the tv from the mains and call a repairman.

0ne of 3 has failed:
(in order of probability):

1. Backlight inverter
2. Power Supply
3. Backlight

Please seek the expertise of an experienced TV repair technician - as they contain potentially lethal voltages that must be properly discharged before work can begin.

Thanks! ! ! !

SOURCE: Sanyo LCD TV has green light , no picture or sound.

You have the classic symptoms of a power supply failure. Visual inspection of capacitors is not a reliable method of solving the problem

Why does the Sanyo tv have a flashing green light and not turn on?


This is because the blown power board will get power to light the LED but not enough to operate the picture and sound. Check that the caps on this board are blown, and replace with exact parts. The fix can be $10.

If the power light is flashing, it could be excessive or shorted voltage or that the capacitors are malfunctioning. In this case, replacement capacitors or a new power board is in order. Contact a professional for help.

If you hear a chirping sound, that is the shutdown circuit activating, indicating a problem with the power supply.

Start by making sure that all of the set-top box cables and cords are firmly connected and that the set-top box is turned on. Also, check to see that the TV is set on the correct channel and that the DVD player is not on.

Blue light flashing no picture or sound


Sounds like a main board problem, I've worked on quite a few Sanyo's and their main boards are notorious for failures.

37' lcd sanyo. sound no picture. no backlight. when turned on screen will flash on for a second, power indicator light stays on . Hear electric static sound when screen flashes


Check the lamps connectors on the backlight inverter board make sure they are not loose. You may be ahving failing inverter board itself.
