Sylvania LC220SS1 bad inverter

[ruben53]

Hi, my tv Sylvania LC220SS1 had standby red light on when try to turn it on
the green light blinks 21 times and then the red stanby light.I replaced the
power supply that also has the backlight inverter and the tv works normal.
I want to know if somebody can guide me to repair the board if it is possible.
I am not expert technician but I have repaired some tvs as a hobby.
Thanks for any help.

HV Transformers could be bad or the Inverter IC/circuitry....Most time with these TVs is if you can get a replacement board, say thank you and replace it. To repair a Uni-bd like that would be very frustrating and time consuming from my experience and to top it all off you say you are no expert. The thread will get very long and time WILL be wasted. Good luck on your replacement Bd.

but now I know its not that easy.

For future reference:

By the looks of the rusting RF section, this TV has been probably out in the trash and moisture definitely got to it for a while. Dont bother. Once you see rust or oxidation
