Diagnostic Revealed Failed Power Supply Unit

Circuit City tentatively diagnosed a failure in our power supply unit (without any testing). Won't guaranty that is the problem and wants us to spend big bugs to "see". Can we purchase this part and install it ourselves for our JVC? How and where do we purchase? Are there manuals that will help?
We are in Richmond, Virginia

    The self-diagnostic lamp 1 (at the top) blinks continuously--all are red. Thanks!

    Tell me in detail what your set is doing. If there are blinking LEDs involved then tell me how many times it blinks and what color it's blinking.

That blinking code means that the temperature is too high in the power supply circuit. You might very well have a bad power supply board. But I don't suggest replacing it unless you fully know what you'll be up against. There are several plugs and flat ribbon cables and if you hook it back up wrong it could do other damage. To purchase the board you can go to www.tritronicsinc.com. If you're unsure of what to do then I suggest you take it to someone who is an authorized JVC service center near you.

Chances are also if its Dead to start with is replace the fuse in the supply line.(Simple test)... Circuit City is not qulafied to do anything other than plug it in and try to turn on. Corporate will not let them even have a soldering iron for the most part as the Liabilitiy is too high in their opinion.. (Weve had a ton of various Items referred to us by all of the Big-Dogs/Take the diagnostic fees and run types)..

Just another option and Am not trying to down you either C-dog..

    That means its not Dead and perhaps C-dog is more better to talk to.. (I'm shooting in the dark and Dead means No power).. If he knows the codes? Hey run with it bud!

No power at all


Possible that the main controller has failed if there is power till within the power supply unit of the controller.
You need to probe into the power supply unit to confirm for a fuse failure, a link failure on the Low tension circuit, a failure to provide power to the controller.

Toshiba projection tv 50 inch


Something is preventing the power supply from operating:
Possible causes in order of likelihood:
1) Convergence amps failed overloading the supply (See if you can disconnect them)
2) High Voltage circuit has died. (Right on schedule since your TV is 10 years old)
3) One of the CRTs has shorted
4) The power supply itself has died (Is there a lot of dust covering it?)
See if you can isolate the failure by working down the list.
Hope Ya Fix it!

Protron 32 inch tv sounds work,but black screen


Possible that the back light circuit has failed. You need to check on the invertor circuit , it can be due to failure of the power supply to the unit, if so trace back to the power supply and check for open fusible resisitors or fuse.
If power is absent check on the SMPS unit.
If there is power then th drive or the transformer is a suspect.

hi welcome to fixya
i want to clarify first the problem sir so as of now the problem with your tv won't power on then you are using again the old main board is that right ? when you use the new replacement main board the tv is functioning will the only problem is that the HDMI / DVI inputs doesn't work. and now you encountered power supply problem like won't start up or something that cut the supply in which the stand by indicator is turn off so as my idea it has a problem with the old board. but before you come up with the board making sure all the connectors coming from the power supply is properly connected to the main board as will as flexible and lvds cable for the T-con board is properly inserted.just let me know if is that what you are asking for so i can give you additional solution thanks for consulting the fixya.

This oven is programmed with a self diagnostic failure code system which help for troubleshooting -H97 and as described above "mica piece and burnt smell" sound like Inverter Power Supply. DO NOT try to repair or re-adjust preset volume on the board. It is very dangerous to repair or adjust without sufficient test equipment because this circuit handles very high voltage and very high current Operating a misaligned inverter circuit is dangerous due to the Very HIGH voltage and current that is produced by this board.

Defective board must be replaced with new one -INVERTER POWER SUPPLY.

IT Won't power up.


Possible failure of the main power supply unit which is a switch mode power supply.( SMPS).
You need to disconect the power supply to the printer and open the panel to check the SMPS unit.

Please check on the link below for tips to check the SMPS unit. If this is not possible check with a power supply unit to confirm before you order.

My tv does not turn on


Hi,

This problem is likely a failed power supply. This is a known issue with this model TV. It will normally occur soon after the warrenty expires. It can also be caused by a voltage surge produced by a power failure. You might wish to unplug the TV for an hour or more. If this power reset does not allow the TV to turn on component failure is indicated. These sets are assembled using the wave soldering process they are known for having cold solder connections. The safety circuitry shuts the TV set down or will keep it from turning on when it detects a problem. This model of TV has over 2,000 parts, which includes millions of transistors inside the integrated circuits. The capacitors will change value, leak and become defective. Resistors will change value and burn. Diodes and IC can go bad. This may have a domino effect and cause other parts to fail. Replacing one defective part may make the TV operate for a short time but the part will fail again if the parts that caused the failure to begin with are not replaced. The only way to know for sure which parts that are no longer within factory specs and for a proper repair all the electronics must be diagnosed by someone with the correct electronic test equipment specifically designed for TV service and the skills to use the test equipment. I wish I could tell you there was a quick fix or button to push that would fix the TV but that is not the case or the solution needed to get the TV operating correctly.

Let me know, if need further assistance.

Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!

The 'protect light' comes on Fender PD150 Portable Sound System


The protect circuit is activated by a current sensing transformer in the *input* of the power supply. If any of the subassemblies of the unit (or all of them in combination) draw excess current then the protect light will illuminate and the power supply shut down to prevent any damage to the system.

The circuitry in the power supply is fairly robust as well as fuse protected so it is unlikely that the power supply itself has failed. More than likely one of your output power transistors has been shorted and it is easy to check this yourself if you are interested in doing so.

Furthermore if you follow a few *simple* precautions you can do this safely and confidently.

Post again on this thread if you are interested and I will spew the details.
