Overview of capacitorLM358 for handphone

Utilizing the circuit designs perfected for recently introduced Quad

Operational Amplifiers, these dual operational amplifiers feature 1) low

power drain, 2) a common mode input voltage range extending to

ground/VEE, 3) single supply or split supply operation and 4) pinouts

compatible with the popular MC1558 dual operational amplifier. The LM158

series is equivalent to one–half of an LM124.

These amplifiers have several distinct advantages over standard

operational amplifier types in single supply applications. They can operate at

Sony Convergence board question

Is a KP65WS510 "D" Board interchangeable with a KP51WS500 "D" board.

Their STK IC's are both 392-560.

My service manual covers the 51", 57" and 65". But the olny difference here would be one is a 500 and the other is a 510. Im hoping the newer upgraded 510 has the same D board.

If not, well, Im SOL.

 

Anyone???

 

Sony KP65 WS510 Convergence IC replacement help!

I need to find out where a trace goes that was lifted by IC 8001  on "d" board pin #3  before I fire this 300lb beast up again.

I have the schematics but it doesnt clearly show where the trace is supposed to go. I lifted the #3 solder pad on IC 8001  and part of a trace close to this pad was also lifted and i have no idea where its suppposed to go now. I tried to follow the trace backwards but it doesnt go to any component.

If you have an email I can send a pic for you.

Sanyo DP26648, shuts off

I have a Sanyo 26" HD LCD TV.  No standby power light.  TV powers on for like 5 seconds then dies.  I figured bad caps, but they look fine.  So I'm not sure if this is a power board or a logic board problem.  Any tips?  I have been reading around and the faact that there is no standby light leads me to think its a power board problem.  I checked the caps and there is no bulging or blown ones that I can see.  I know that this doesnt always mean they are not bad, but not sure.
