SOURCE: I haveSansui 1403ctv the tv set is dead.no output from smps.When I switch on the tv immediatly switching transister(c1802) will be short.

Check the freewheeling capacitor connected to the collector of this switching output transistor for open. Check the serial resistor too.

Ihave 14 inch jcv tv first i thought it was dead bt then when i check i saw the fuse has blown i get new fuse to replace it and when i try to switch the tv it blows the fuse again & again .


Hi Aderajew, The new fuse also blew away means there is some shot circuit in the TV. No more fuse replacements please. There is nothing more you can do yourself.Take the set to some technician or a service center. Good luck.

B n O 8000 speaker dead, is there an internal fuse, output from tv ok mains fuse ok, no mains indicator light hence question


Fault with 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.

Tv does not come on with off on switch or remote. Set completely dead. VCR doesn't run either. Fuse is OK and circuit board looks like new. Nothing looks overheated.


Quite possible that the fault is relative to the power supply of the TV. So it is important that the voltage is measured of the output in the SMPS - switch mode power supply.
If there is no output the SMPS is faulty , failure of driver or frequency oscillator.
Please check the link below:

Once the power supply is restored the voltage feed to the processor and sub sections must be checked, for failure of any regulator or fusible resistors

When power on SMPS is totally dead chek the fuse; fuse is ok switching transistor also ok pls help


If power out of the SMPS is the issue then a short on the secondary side can also be the issue in which the optocoupler can shut off the feed to the SM driver.
So if your voltage is present at the SM driver and the oscillation of the invertor chopper is good, check on Sm transformer for fault or the secondary ccirrcuit may have short.
If oscillatiion is not present , check and change the Oscillator IC.There are feedback loops into the circuit and the diode/capacitor can also be faulty.

TV IS DEAD. NO POWER AT ALL. HAD A SERVICE TECH LOOK AT IT. HE SAID THE PCB HAD TO BE REPLACED. IS THIS A COMMON PROBLEM? IF SO , WHY?


If the set is totaly dead then the first place to start is with the SMPS (Switched Mode Power Supply). However sometimes other parts will cause the Power Supply to short out as well. If and when the Power Supply is replaced and the set comes back to life and operated with a Menu then you are probably ok. Note: On your set when replacing the SMPS the tech Must adjust the SMPS voltages to the Panel Voltages. There is a sticker on the Panel that list the voltages the tech must adjust on the SMPS.

Sony Tv Model KV2162 M9


The SONY 2162 is a Old Warhorse. It was manufactured nearly 20 years ago. If the set is dead, and if no one has tampered with it, it can be repaired. One problem I found often in the 2162is that it's mains ON OFF switch failed regularly. check that.If you have knowledge of Solid State Electronics, please carefully open the Back Cover and first check the fuses. If they are ok, then check the SMPS switching transistor. If it is short circuited, then replace. Also check the Horizontal Output Transistor at the same time.
