THERE IS NO audio frm my fisher tad-9925.....the ic has just been replaced but still no audio.....cd is playing but cant hear anything


Its a little hard to diagnose over the computer.
I assume there is no sound from the amp EVER.
I assume you have tried other sources.
I assume the unit worked OK until the IC blew.
I assume you replaced the IC yourself?

Often, parts with the IC also fail. There maybe fuses that look just like little resistors along with the IC. They might be blown.
There are parts in the circuit to test if there are speaker problems called power resistors. These will frequently open circuit when the IC Blows - you won't be able to see anything visually.
If your stereo normally makes a 'Click' sound just before the sound comes on, and now there is no click, this indicates the repair of the IC is not complete yet - find the blown part.

I have a Lakewood mdl 5600/7 oil heater. Love it. It seems to have given up. I unplugged it for a while, relocated to different power source, still no lights or anything else. Internal fuse? If so, where?


I had the exact same problem and I took the front panel off and found the bottom thermostat was burned up when I bipassed it the heater worked so I know this is the problem. Its the small thermostat attached with two small screwes to the heater. It is a KSD301 16amp 125volt 160degree themostat but I am having trouble locating one. They seem to be chinese made and mostly have to be ordered in bulk. When/if I find one I will post again

Lining up the colors


Your symptom sounds like a damaged convergence IC.

This is a common failure for this particular television. The power light might be blinking indicate a short in the power supply

There are two and large IC’s that control the convergence in a big screen set. Some of the newer sets only have one. They are secured to a very large aluminum heat sink. They will have a part number stamped on them that will start with an STKXXX-XXX, like STK392-110, and they are located on the signal board (on the left as you look into the back of the set).

Along with the convergence IC’s there will also be some associated components that will need to be replaced as well. There are some resistors that are part of the convergence circuit that will be open and need to be replaced. Most likely these will appear charred in the center. If you have an Ohm Meter or a DVM, check all the resistors that are close to the IC’s and you should be looking for either ones that have opened or have changed values.
There are also two resistors on the front of the board located in the middle that are fusible link resistors, these should be checked for opens and replaced if they are found so.

I would suggest that you contact a service center in your area for a complete diagnosis and repair, as this type of repair can get a little tricky. But if you want to repair the set yourself, just remember to be careful. The capacitors and CRT’s can hold a charge and may shock you.


If one of the convergence IC’s are found to be bad, I would replace them both, if one has gone bad the other may go soon. I usually order my parts from Andrews Electronics in California, they will have the OEM components that you will need.
Their site is http://www.andrewselectronics.com/welcome.aspx
And their phone number is a 24-Hour Order Desk: (800) 274-4666
I recommend the phone order so you can talk to the person about the different types of IC’s that are available.

I would also advise that the convergence IC’s be OEM or better, just because they are cheap does not mean that they are a good deal. I have seen the cheap IC’s fail after a short time, even though they look exactly like the OEM IC’s. I think that the bottom line is that you will get what you pay for when it comes to the parts.

You can also try http://www.tvrepairkits.com/ , I have not tried them yet, but they do carry OEM or better parts.

I hope this information allows you to resolve this issue.
If you need further assistance please comment to this post and I will try to help you further.

They will have a part number stamped on them that will start with an STKXXX-XXX, like STK392-110, and they are located on the signal board (on the left as you look into the back of the set).

What happens in the Panasonic set is that the convergence IC’s will short and cause the power supply to shut down from the overload of current. You will want to replace these before it shorts out the power supply and shuts your set down.

Along with the convergence IC’s there will also be some associated components that will need to be replaced as well. There are some resistors that are part of the convergence circuit that will be open and need to be replaced. Most likely these will appear charred in the center. If you have an Ohm Meter or a DVM, check all the resistors that are close to the IC’s and you should be looking for either ones that have opened or have changed values.

Mod. WS-655111 Fuse F9A04 & 05 bad. Set goes on & right off


You can order a replacement STK393-110 for this model (62HM95) from a major parts distributor at the link below:

Mitsubishi WS-65511 Replacement Part Convergence IC STK393-110

You would probably have to recalibrate the convergence after you install the IC. There may be a convergence kit available as well.

Same old red convergence issue


they wont show any signs of being bad if you cant adjust the convergence the ICs and possibly a few of the convergence resistors will need replacement. You can get new ICs and resistors at the following link and they come with free instaltion instructions.

How to replace the color wheel on a RCA DLP


RCA DLP color wheel replacment is most efficiently done from the behind the screen, not the back panels where the guts of the DLP are located.

From there you do not need to remove anything but the color wheel and disconnect the two wires.
