4 blinks??? on my Sony TV

I just replaced the 2 covergence boards on the ''D'' board. Also replaced a pico fuse on the ''G'' board. Put it all together and now the TV will not power on and it has 4 blinking lights. I know it's a V-stop fault code but where do I start troubleshootin

What are the specific pico fuses for my RPTV


The amperage is marked on the board right next to them--likely if they go to the convergence circuit they will be marked 5a or 5 amp.

Usually but not always there are more at the convergence chips.

I presume you did not look closely at the board where the two you found are---Sony marks everything.

Replaced Convergence chips, same problem


This set has pico fuses on convergence board and also on G power board, there should be 2 5 amp pico fuses on power board.

If convergence is bad exactly as before double check the power board fuses and check to see if voltage (it is marked!) is there with power board disconnected from chassis..

Kd-46wt500 sony big screen colors dont line up is projectors goin out picture on tv is blurry pic looks stretched out as well


Can you verify the model number and see if its A KP46WT500 model? If so chances are just the convergence Ics ( stk 392-560 ) and pico fuses are the problem. There are 6 3.5 amp pico fuses directly beneath the heat sink fins on the D board ( where the Convergence ICs are located) Check those six pico fuses and also two 5 amp picos on the G board ( where power cord plugs in) if any of the picos on either board are open then the Convergence ICs will require replacement.

Did you check the two pico fuses on the G board? Usually at least one will blow when the original ICs failed. I am attaching a pic that shows the 2 pico fuses on the G board.

Did you check the 6 pico fuses on the D board and also the 2 pico fuses on the g board. Usually one on each board will require replacement with the new ICs. Then just pressing the perfect focus should reset the convergence after the picos have been tested and the blown ones replaced.

Hi, I got the same problem, you need change the pico fuse, the 2 STK, if you will do that and does not work need change the G Board ( Power Supply),but you can repair it, unplug the wire ac det and the TV will power on, but don't forget replace the pico fuse.

I believe there is a power board on the left side when looking from the back. It will be vertical, right next to the board you worked on. Take that board out. I believe there are about four pico fuses on that board. One or two of them will be open. Replace the fuses and you should be good to go.
