Good day!

That problem is 2 causes,its either power supply or system board.
This are some D.I.Y procedure for troubleshooting.

  1. Open the back cover by removing all screws at the back.
  2. Try to look at the power supply board and find the leak/bulge on top capacitors.If you found,replace it with the same type and ratings.
  3. If the power supply doesn't have any leak capacitors.Try to power it ON to perform voltage checking.
  4. Check the output voltage of power supply such as 5vdc,12vdc and 24vdc by using voltmeter.If this 3 supplies having a voltage drop or flickering voltage while on power ON.Check the following parts on the power supply,change value/open resistor,shorted transistor and diode or repeat step # 2.
  5. When the output voltage is stable and all parts looks OK.The problem could be on system board.Unfortunately the system board or main board is not for D.I.Y because the parts inside is very logic and very sensitive.That is replaceable.
Thank you and good luck.Please don't forget to rate my answer.

I have a Bush 31 inch smart tv and it switches itself on and off but when Its off red light keeps flashing and i cant use the remote please help im getting frustrated


These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices. http://electronicshelponline.blogspot.com/
Blinking codes details to many popular brand TVs are given. Surf the site with patience. If blinks continue without any pause, the main board is faulty.

I have been given a Bush B320DTR, without a manual, connected it and was working fine, set it to record a few things then put it on standby, now cannot get it machine to switch on, the sticky label says...


Sometimes simply unplugging the unit from the mains will solve this problem. Are there any lights showing on the recorder when plugged in? We stock the Bush B320DTR at GoGoDigital - if you want a copy of the manual please do email us at helpdesk@gogodigital.co.uk

Try Checking your remote and make sure it did not short out by taking out the batteries and see if it continues turning on and off. if so then i would recommend replacing the remote. if this does not work try putting tape over the ir receiver and see if it continues, this will check for interference.

Hi John
If you havent allready try unpluging the unit from the mains.
Leave out for 5 mins then plug back out & allow system to reboot.
Cant guarantee this will work but it does solve a lot of digi box problems.
