In stock


Coppell TV Repair LLC is offering a repair kit for a few different failures we've seen and resolved in power supply board APS-299/C (CH) and its variation APS-299/CW(CH).

Failure symptoms

This repair kit contains parts for at least two separate failures we've seen develop on power supply APS-299.

Failure symptoms are as follows:

  • Totally dead TV, no standby voltage produced by the power supply; very low bi-directional resistance can be measured over leads of electrolytic capactior C6203 located near standby transformer T6201;
  • TV has standby LED, but when powered on fails to come up; ceramic resistor R6536  on the power supply is blown open.

Note that TV behavior may be slightly different depending on the failure degree in the affected components. Sometimes you may not have clear indication of a failure and different failure symptoms (e.g. TV may work for a short time and then shut off) and it may still be the same parts that cause it, but it may also be other parts.

It is the service technician's responsibility to identify the problem and choose and perform the proper resolution.


Brand new replacements for components at positions Q6101,Q6102, R6540 and IC6501.

More parts may be addeed over time. If you receive component that you can not identify please contact us.

We recommend replacing all of the parts as we've seen all of them fail under different circumstances, suggesting they simply age and if you are so and so working on the board you are better off spending a few more minutes improving your chances of not having to do it again in near future,


Easy to medium. Generic soldering equipment should allow doing the job.

Patience and attention are always recommended.

Improper handling may cause additional damage. If you are not certain you can undertake the service consider using our repair services instead.

    Coppell TV Repair LLC does not guarantee that this product is all that is needed to resolve the problems with your TV.

    Most of the repair kits we offer are based on first hand experience servicing boards at our repair facility. 

    Over time they may get expanded with our own experience or information from manufacturer service bulletins, customer feedback etc.

    Yet failure can be unique and there can not be guarantee that what has worked one, ten or even hundred times will also work the next one.

    Just as important, every repair involves about equal portion of quality of parts and quality of worksmanship and as we have no control over the worksmanship quality unless we are the ones performing it we would be unwise to provide warranty of the products utilized by that worksmanship.

    As such, no warranty is offered on this product once the components in it are soldered on a board.

    If you would like warranty please see if a REPAIR SERVICE is offered instead of a kit. Unless otherwise noted all our repair services do come with a standard warranty.
