SONY Convergence Problem

[zokka]

Hello,

i have a problem with my rear projection tv. "sony - kp-46s4"
i changed stk 392-040 both chips but it wasn't solved.
also, there is an item that was broken. its symbol is shown below.
but i don't know what it is can anyone help me about it.

Fuseable resistor i think, .1 ohm 1/6 watt. You have to find out what made it burn open.

thank you for feedback, i hope to find it.

hello, i found a fusible resistor, but it is not 1/6 watt, it is 0.1ohm - 1 watt. will any problem occur?
i replace it and convergence problem was solved. everything is ok, but i'm not sure will i have a problem?

Well, the replacement is rated at six times the power of the original. The fusible link was protecting something, and with the higher rating it probably isn't any more.

If you can measure the voltage drop across that resistor during normal operation it would be useful.

Something less than 0.1 V would be OK (lower is better) Anything higher is probably an indication of an existing fault (certainly anything over about 0.15V would be a danger sign).

Thank you for warning. I measured all the resistors, they vary of 50mV and 95mV.
