Faulty power supply board

Hi, I have just had my recorder checked out as all displays failed while in stand-by. I was told the power supply board had a fault, and was no longer available. Can you suggest any sites for a replacement?

    Hi, can you tell me what component it was you found to be faulty on the power supply board, it might be worth trying a replacement component rather than scrapping the whole machine.

I have exactly the same problem. Indeed the power supply was defect. I have repaired it. Now the display is working but it is still not working : It displays LOADING... and that's all. Probably the controller card (the one with the LSI LOGIC chip) is also defect. It is impossible to repair, it has to be replaced.
I think this recorder is not 'CE'.

What makes the HISENSE LCD (Model LCD 42W58P1) power supply failed to produce output voltage goes to the main pc board?


Hi,
First of all the power supply makes 'Stand By 5 or 3.5V which goes to main board. When we give power on command to the TV the main board sends 'stand by or Power ON' command to the power board which then makes other necessary voltage for the main board as well as other sections. If the power board does not receive 'Power On' command from main board, it will not produce the necessary voltages to operate the TV set.

My tv has no power?


Let's assume your post in flat panel TV's is for an LCD TV. Since your make and model is not provided, only basic info can be provided. Most LCD TV's have a stand-by power LED that is either on or comes on when the TV switches or blinks in the event of a failure. If you don't see a light when there should be one normally, then you may have a failed stand-by power supply. The stand-by power supply provides a voltage necessary to allow you to command the tv to turn on with the remote or via the power button on the tv. If the power light is normally off and normally comes on when you use the remote to turn it on but nothing happens it can still be the stand-by power supply failed. The next level of the power control is done by a small tv micro (processor) often on a board that handles audio that tells the main power supply board to turn on. To render much technical assistance you would have to know how to take voltage readings on the PSU. If there is no SB5V you either need a PSU board or there is an issue from the AC line to the PSU. It can get complicated from there depending on the failure. I assume you know the power outlet at the wall is good and the remote battery is good and you have tried the power button on the tv to eliminate a faulty remote.

Power 48v check


Hi
Either the power supply is
not generating a proper 48
Volts or the controller board
is not detecting a 48 Volt
output from the power
supply board.

1. Make sure the power supply
board is correctly connected to
the controller board.
2. Power on the printer. If the
message appears, do the power
supply operational check (page
195). If the power supply fails the
check, replace it. If it passes the
check, go to the next step.
3. Power on the printer. If the
message appears, replace the
controller board. Record the
message and return it with the
defective board.

Fitnex t60 display says prg bad, what does that mean and how can i repair it


1) You must test first the power supply for +5DC for I.Circuit( Including EPROM, ROM, etc)
2) Test the flexible cable between KeyPanel and display board, and clean.
3) Chechk the connector between Display Board with the lower board(Main Controller Motor)for loose connection, loose wire.
4) Test the transformer controller supplying the 12VCA, to the power supply at the Main Controller Board since this supply the +5vd to the Display Board.
Finally you must have Strong Conclusion if the problem is 1)Display Board faulty, 2) Power supply Faulty, 3) Transformer Controller Faulty 4) Main Controller Board Faulty.

For All test you must use Dvoltmeter.

Hi, when i turn my Techwood 37 off on to stand by it turns its self back on again despite advise of removing the batteries from the remote. It has also started turning its self on and off whilst you are...


Hello,

It's the problem of overheating in the power supply board of the TV.on the power supply board of the TV there are few capacitors and IC.any of this IC is got short or may be weak.so due to this when you start the TV the current passes from electric outlet to the power supply board of TV.but when the current passes from that weak/faulty part at that time current gets stopped or slow and the board overheats and TV shuts off. this is a common problem faced by many other users too.the possible option to solve this issue is to check the power supply board by a meter and continuity tester and replace the faulty component on the board which is short due to which power supply board is getting overheated.

I hope this will help in solving the problem.....

Vp50hdtv20a does not turn on, power supply board was replaced about 6 months ago. Could it be bad again?


it is possible the power supply board that was replaced was a refurbished board. you also may want to think about underlying issues with the sustainer boards causing the power supply board to fail.

Power supplierd but does not start recorder no


Hello:

If the unit is competely dead, then you may of blown a fuse or the power supply has failed in the unit. If you take off the top of the unit while unpluged check the fuses near where the power cord attaches to the inside of the unit this is the power supply area, If you have indicators lit or the display is coming on then the unit may have a bad power supply or the System control board has failed. It which case its cheaper to just purchase a new unit.
