hey,

About 4 years ago i bought this tv, the Sony KV-21CL10B, and a week ago it suddenly stopped working. The only thing it does right now when i try to power it on is flash its standby led twice.

I've looked up the error code on the internet, but the only thing i came across was the general explanation of what 2 blinks means:
Quote:
B+ over current protection (OCP), unit goes to the standby mode then displays the 2 blink fault. Could be a short in the power supply of any of the circuits.

I'm not very familiar with electronical components and such, so my question to you is whether you can narrow down the problem for me and explain the above message a bit or point me in the right direction.

Thanks in advance, Gero

check q533 for short circuit, if it is replace it with a genuine item, copies are not reliable, and replace the line output transformer, it may also have damaged components in the e-w stage and abl circuit, also not unusual for line output transformer failure to kill the micro in these sets.
