The pico fuses look simular to resistors but are a solid color and has the value writen on it. the component location will start with "F" (Fxxx) or in some cases "PR" (PRxxx). F stands for Fuse and PR stands for PRotect.

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.

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.

Call Mats Electronics they have everything 1-800-628-1118 and did you CK the pico fuses in front of your ICs and there is some behind them picos look like resistors they will be green or yellow 5amps 6 amps If convergence it not working after you hve replaced ICs CK the pico fuses.

Convergence problem philips rear projection tv.


All convergence circuits require two voltages which are equal, one being positive the other negative. Check the power supply for these two voltages and then see if you're getting them at the output ICs. I suspect one of them is missing or low. If there are no cooked resistors near the ICs, inspect the fuses that protect those two voltage sources or the regulating devices themselves.

Samsung pcl5414r power resistors and pico fuses??


Hi again and welcome back to FixYa,

Appreciate the direct "Ask Me'.

Based on your original post, only the STK ICs were replaced. Presumably 392-040, the surrounding resistors and pico fuses could very well have been affected as well. Depending on the board revision (pls confirm location numbering on the actual board), the resistors could be:
RZ104 -RZ106 - 270 Ohm 1/2watt
RZ133-RZ135 - 27K Ohm 1/16 watt
RZ136 & RZ138 - 3.3K Ohm 1/8 watt
RZ146 and RZ147 - 3.9 Ohm 2 watt
RZ148 and RZ149 - 150 Ohm 2 watt
while the pico fuses would look like the image below.

Good luck and Thank you for using FixYa.

Pico fuses could be through out the board... And the service manual, if it has a parts list, does give the board designation for all the picos on it...
Although these are good pictures they don't show a great deal of detail... But picture 1 & 2 at the far left, above where the two sets of blue wires are plugged in - looks like a pico piggy-backed on top of another pico... Sometimes it's easier than desoldering the original pico just to piggy back them in this fashion - but it's not a good practice.
Start there and read the designation on the board... Then look in the parts list section of the service manual and find the others by their designation.

Pico/ Resistors what are these??


Pico means small and these look like little small resistors, but don't have stripes like resistors, just part numbers. They should measure as a dead short and be in the immediate vicinity of the STK's
