My bush tv won't switch on


Could be an open internal fuse, a defective switch, or power supply failure.

My bush tv won't turn on how much would repair cost


Fault in the main power supply regulator board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts.

It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size. Repair cost will depend on the cost of the power board.

Hi I have a argos brought bush led tv that is only a year old and very rarely used but now for some reason it will not turn on at all I've changed fuse etc but nothing I'd say the tv has only dine abo


When you say not turning on is it completely dead, or has it gone into stand by mode, needing the remote to fire it up. Might sound patronising but are you sure both fuses are good?? Might have been in a spare room and got damp on the circuit boards and blown a internal fuse.

Bush tv model idlcd32tv05hd no pwer going to tv


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.

If the TV goes off completely, then is usually a faulty power board.

If the TV goes in standby, then it is in protection mode.

Ensure also that the fault is not coming from a faulty receiver box sending
bad signal, check if you get same problem on DVD with no receiver box
connected.

Try first leaving the TV power cord unplugged for some times, let say one hour or so.

The flashing light indicates a diagnostic state called protection.
When the TV goes on protection there are only two possible causes.

1The internal circuits are jammed because of electrostatic charges accumulating on capacitors, or because of a wrong voltage read by the main chip on your monitor controller board. this started the protection circuit.

2 The protection circuit detected a wrong voltage or abroken contact, identified an internal fault and kicked in , starting the flashing light.

If you are in situation one, then the TV will reset just unplugging power cord for one or two hours,sometimes even minutes.

If you are in situation 2 , then there is an internal fault.

If under warranty contact the manufacturer ringing the number on the user manual

If you want to repair at your own expenses, just locate any good qualified repairer.

On LCD Pay particular attention at inverter and power board, power board can be inspected looking for bulged or leaking capacitors, then tested with a multimeter. The inverter is more difficult to test , there is need to read voltages, should be done by a tech. Also the LCD controller board can cause same problem

On Plasma, test Sustain (Ysus/Zsus) / Buffer boards , cables to plasma, digital board and power board.

On Rear Projection : check lamp, lamp ballast, power board, and convergence.

On CRT TVs, check ballast , flyback transformer, CRT, Tuner, Convergence.

Bush TV Dead MODEL: 5693D


switch mode power supply? it has a in or primary side and out the secondary side of a switch mode transformer.

check the driver IC that runs Q102 it makes a oscillation that Q102 amplifies. now the secondary if has a short will blow the Q102 look for shorted rectifiers in the secondary and fuse resistors that are open, even go far downstream and check the HOT for short.

TV won't power up and blows the fuse


A 10 year old RCa most likly has a bad Horizontal output transistor as well as the main High Voltage transformer and The transformer is no lonmger available from RCA. The replacement wont last longer then a year if your lucky. My advice on a set this old ?? Buy a newer one!!

My tv power does not come on


This set uses a switching power supply. Usually when there is a short on the output side of the switching transformer the supply will just shut down and refuse to operate but normally will not blow a fuse. If the fuse blows suspect a problem with something shorted on the input side of the switching transformer such as I801 regulator IC, diode bridge D801,or other shorted component. Perhaps someone else could tell both of us any other part that could cause the regulator to blow and should also be replaced to prevent regulator failure in the future.
