IC is wrecked


When you indicate the Integrated Circuit is 'wrecked', and you indicate due to lightning, I can only assume you are talking about the Power MOSFET's, in the DC - DC circuit on the motherboard......

Example using the HP Pavilion dv6000 series, and Pavilion dv9000 series of Notebook PC's,

http://mayohardware.blogspot.com/2010/04/important-parts-on-dv6000-and-dv9000.html

Going further using the example.......

The Power MOSFET's used is the Fairchild Semiconductor Industries - FDS6679 - Power MOSFET, and the Alpha & Omega Semiconductor LTD - AO4407 - Power MOSFET.

http://www.mouser.com/Search/Refine.aspx?Keyword=FDS6679

Here we see the FDS6679 is Obsolete.
Using the cross-reference example shown, for availability and price,

Obsolete also. Using one of the cross-reference examples given,

Sa-ht545 error code f61- comes up upon statrting


F61 just equal 'power fault'
Generally a fault with either audio power amp ic (IC 501) or power supply ic IC 502.

As both said ICs get very got first remove bottom steel grill and with the power off and capacitors drained (shorted together with a low ohms resistor or leave unit powered down for a few hours) resolder the ICs legs if there are any signs of cracks aka dry solder joints.
Hope that helps.......

My stereo C918X turns off every time iput the volume up displaying f61


The audio output ic is getting to hot due to bad connections or ic failure. Check the speaker wires for shorts, if okay! semiconductor needs to be replaced.

Picture looks like it is in 3D..What would cause this?


Convergence ICs are smoked. Needs dis-assembly, replace ICs, maybe fuses, usually minor adjustment.

The Red Blue and green images do not "converge" or line up. Caused by heat, power line bumps, lightning, collisions with vacuum cleaner, etc. Small amount of damage happens with each occurrence. Eventually semiconductor material at junctions inside STK IC is depleted and will not handle normal current.

In Canada, Call me.

Light come on but not getting any sound.


First check out that the power supply has knocked down the voltage to the smaller levels that semiconductors work with say 12 to 25 volts. Look carefully at the main semiconductor. Check that it's got a voltage of this size going to it. If it is an IC, one pin should have it! If the power is working it's way to the main parts. Then I would think about replacing that main semiconductor. If it is an IC whip it out anyway.

My panasonic turns on but shows the letter f61 what does that mean?


F61 just means 'power fault'
Generally a fault with either audio power amp ic (IC 501) or power supply ic (IC 502).

May also be the fan if it has one make sure it is clean and can spin freely.
Hope this helps. Thanks
