Video on how to replace defect capacitors

Replace it.

Not likely! Suggest swapping input connection, red RCA connector to white and white to red and see if problem swaps speakers.

If still left channel bad swap speakers left to right see if problem follows speaker.

Check balance adjustment and confirm that it is set to the middle!

Check all other inputs and confirm always no left output.

The goal is to confirm that the left channel is defective!

The service manual is MS3102101 would normally be available from Radio Shack.

Check for defective capacitors or failed solder joints on the PC board. These units are repairable even by DIY however replacement recievers are relatively inexpensive.

Hope this helps?

Hello,

The issue you describe is consistent with a power supply board issue. This is the board where the AC goes to. This problem may have occurred as a result of irregular power supply, or excess power supply or power surge.

The TV is receiving current but cannot circulate or transfer the current to other necessary part of the TV because of the defective power supply board. You might be lucky it's just a blow fuse. Also a defective transformer can cause your TV not to power on.

All these can be checked on the power supply board.

But more often bad capacitors causes problem on the power supply board. I do not think the power board needs replacement, rather those defective capacitors is causing this issue. Open unit up and take a look at the power supply board.You will probably see one or more electrolytic filter capacitors that are bulged up in the top-not perfectly flat like the others.

The value of these capacitors will be different, most likely they will be somewhere around-820 to 2200uF/25 V( or /10V sometimes)

You can replace them with same values but I would recommend the voltage rating to be higher(like 35V for an original 25V) for reliability purposes.

What happens is,these bulged top capacitors will cause a low and unfiltered DC voltage=main board will malfunction(the relay will keep clicking until the caps are holding enough charge to bring the voltage up over a threshold point).

You can buy these capacitors at any Fry's or Radioshack store or you can order them online at vendors like "mcmelectronics.com"(look for electrolytic capacitors). After replacing these capacitor(capacitors) most likely the normal operation will be restored. Or you can by a refurbished complete power board to save you some stress.

Note: There may be also some other causes for this symptom ,like a defective T con board ,or main board,but the bulged top capacitors are the most common cause for this issue.

If you don't know about TV repairers, take the TV to the nearest repairman to fix the fault for you. Also, note that TV stores a lot of current, so wait a while before opening the TV back cover.

I hope this helps.

Regards.

Hi, probably the defect might be on the inverter board or power board. possibly there might be a loose contact since it encountered an intermittent events. check if it has a shadow like picture. If it has, it is in the inverter board. check some capacitor defect issues.

Have you had the tv working before?

It sounds like the input/source is not correct.
Is there a button on the tv (or remote) called Input or Source?

Try pushing that.
If you're trying to watch cable tv, make sure the source is set to cable.
If trying to watch a move, make sure it's set to either HDMI or aux.

Hope that's the problem, and not anything more serious!
Have a good day :)

Your video board is defective.The sound indicates your power supply is working.Often the inputs are to blame and no signal is getting through.If a picture appears on TV mode then the problem is on the inputs-it could be loose and needs resoldering the terminals.But if it all happens on all functions then you need to replace the video board.In comes in between the input board processor and the video processor(the board that is terminated to the Plasma screen).

Hi Zzebra22,
I would suggest to watch the video from the link provided if your TV is behaving the same.

Hi,

Appreciate the "Ask Me".

My compliments that you have determined that error code F06 indicates drive motor tach error. This relates to the controller board not sensing that the motor is spinning. This could be attributed to three (3) possibilities:

• motor is not really turning/stuck, a replacement is required;
• motor is turning but the sensor attached to it is defective and therefore not sending signals to the controller board. Pls check the terminals/connectors/wirings; and/or
• the controller board input circuitry is defective. It does not register any input from the motor's RPM sensor. This could be a diode, resistor or logic IC. This would be component level repair requiring familiarity with electronic circuitry and components, use of a DVM and a soldering iron. It wold be easier to replace the entire controller board..

In some instances, it could just be the motor's capacitor that is defective. The capacitor provides the initial kick for the motor to start running. Failure on the capacitor will not kick start hence motor will not start hence RPM sensor says to controller board motor not running.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards. Thank you for using FixYa.

open it up and look for defective capacitors on the video input board and replace them. Should probably replace the 470uf caps on the power board while you are in there.
