    Hantarex 9110 Jitters and high B+

    check every resistor and transistor in the 100 section. you can check them off in the schematic as you go. if your B+ is to high then your image will always do funny things. no mater what B+ HAS to be correct in order for the chassis to preform properly. Peace Buffett

    G07 B+ Question

    replace the B+ pot BEFORE you start replacing other parts. the B+ pot not working can cause all kinds of issues. on some G07's the screen will not go all the way dark if you are using the TPG and some games. if i were you, i would just replace ALL the post on those chassis. those metal pots...

    EZV20 Mario bros wide body sync ?

    yup. seen it dozens of times. the pots on the chassis, the H-Hold and B+ pots are junk and need replaced more often than not. the B+ pot i replace on every Sanyo i fix. the H-Hold pot is a hit or miss if it does not pass the burn in test. replacing the pot "should" solve your issues. Peace...

    G07 B+ Question

    sounds to me you have a issue in the video processing section. i see this on many different chassis. check for any solder bridges, this is the most common issue. if you need it repaired, your welcome to send it in. Peace Buffett

    EZV20 Mario bros wide body sync ?

    don't bother with Deoxit, just replace the pot. that pot is on it's way out. 50 Deg should not have any working affect on the chassis. re-flow the section around the pot as well. Peace Buffett

    Polarity to thermistor 501 on k4900, can I repair it?

    test all the diodes in the degauss and PS circuit. one or more of them may be shorted. you can also test the H.O.T. it may have been taken out when the fuse blew or is the cause if shorted. make sure your rig is running isolated power to the chassis, if not it will cause fuses to blow. if you...

    Help needed: K4951 cap kit vertical collapse

    I am betting there is a crack in a trace or around a pad somewhere. So common to have on theses chassis after work has been done. Give all the big parts the wiggle test and flex the PCB very easy to see if you see the solder mask move. If you hit a brick wall your welcome to send it in...

    bad/cold solder, you have cruddy black leads on the H-Width coil. i know you have continuity but it may not be enough. continuity does not equal good current flow. Peace Buffett

    Stumped: K7400 drops PCB voltages when plugged in.

    Sounds like a cab wiring issue and not a monitor issue. Something is touching in the harnesses somewhere it should not. Trace all the AC side first then the DC side. Peace Buffett
