Question about Samsung TSL3295HF TV

1 Answer

The TV does not turn on. when powered up the TV makes some hissing sounds in the back, but the TV does not turn on and after a couple of seconds it shuts off. The TV is powered and the protection fuse is fine. There is a component FUJ-34C001F (S) or F428-P01-1104 that keeps making hissing sounds before it shuts off. It does not look like the Tube (TV lamp) gets powered at all. Any ideas?

    It definitly sounds like the flyback. It looks like a professinal electrician is required to replace it. I looked at it and did not identify a way to just remove and replace the part. Suggestions?

    Dear sir
    I agree that it must be the flyback. How do we proceed?

  • dotan_omri Jun 07, 2010

    OK, how do we go about getting it done. I appreciate it. I am no electrician.

  • dotan_omri Jun 07, 2010

There are two components in a CRT tv that are capable of making the hissing noise you have mentioned.
1) Flyback transformer(part number sounds like the flyback's) also known as High Voltage transformer that is responsible for producing an image on the tube. Hissing noise indicates loss of insulation on the coil. If the damage is extensive arcing can be seen.
2)Horizontal/Vertical deflection IC. This is unlikely as the part number does not sound like a deflection IC's model. It has 8 pins going into the board. Makes hissing noise when overload is detectes.
Let me know which one of the two it is so that we can proceed with the repair.

    It is not advisable that you do it your self. The CRT acts as a giant capacitor and the the anode cap that is connected to the flyback holds potentially lethal voltages(around 10000-15000V). The replacement is easy but I don't want to risk you losing life and limb. Part costs around 60-90$ replacement should cost you around 50-75$.

    You can purchase the part online. It costs 70$

    You can then have a tech replace it. Half an hour job and should cost you around 50-75$ for labor.

    You can use our repair directory to search for a tech if you are in the
    US. Enter the zip code and choose tv tech from the drop down menu from
    the left hand side and click search. Pick the one closest to you, call
    him and fix an appointment.

Sharp CRT TV from 2007. Won't turn on, makes hissing sound when plugged in.


Dampness in the power transformer will cause this, keep it somewhere warm and with good airflow for a while, to dry for a couple of days, before you take the back off and gently brush the dust off using a vacuum cleaner to carefully clean it out, MAKE SURE TV IS UNPLUGGED THEN TURN THE POWER SWITCH ON TO DRAIN ALL REMAINING POWER OUT. dust & dampness are the usual reasons.

Hissing noise,sound goes off and and i have to turn t.v off and turn it back on


This is a protection circuit that prevents the tv from coming on (to stop damage of the components) ....you need to check your voltages off the power supply and make sure they all read well (EX: 24v12v5v etc). Also look for popped capacitors that would make the values lower than need be for the tv to power on properly.

The hiss is a popped (blown) capacitor! You need to replace it before you keep trying to power on the tv...you will cause more damage

Please rate if this helps!

Monitor won't turn on.


Does the cord plug directly from the wall into the monitor, or is there a power "brick" adapter between?

If there's a "brick" listen to see if the hissing is coming from the monitor itself or the brick. If the hissing is coming from the brick you may just need a new power adapter.

If there's no brick or the hissing is coming from the monitor, the monitor probably needs repair. With the price of LCD monitors these days compared to the price of labor, you're probably better off getting a new LCD monitor. Just make sure you take your old one to a proper E-Waste facility so it doesn't pollute the environment.
