Clicking noise+horizontal flashes

Hi, when i turn on my TV, i hear a clicking noise and at the same time ,on the screan, i see some horizontal black lines flashing .maybe 2-3 lines. not always at the same place.. so that happen only during 5 sec and after it stop. this problem happen only when i turn on the TV, but not every time but the majority of the time. i called a repair guy and i don't remember what he did but he putted a lubrifiant on something. and that worked! during maybe 1 year, that problem was gone.... but it started again!! i called him again and that time, he changed that piece ( sorry, i don't know the name of that piece...). and that worked too!! during 1 year again... and the problem is starting again... before calling the guy again, i want to know if that can be solve for good or that problem will always come back after? that problem can be dangerous? if I wait too long, my tv can blow off? LOL.. thanx!

Re: clicking noise+horizontal flashes

What you are hearing is the high voltage arcing a bit. This is often caused by dust buildup on the high voltage components, & is not harmful. A good cleaning with compressed air will cure it, but this is not a do it yourself job, because dangerous voltages are present inside any TV.

When I press button to turn on my Sony 32 Sony Triniton TV, I hear clicking noise as if TV trying to come on, but it does not come on. The red light for Standby keeps flashing, but, TV does not come

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.
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.
Check and replace damaged component/s at its horizontal scan output section circuit. Check the LOT (Line Output Transformer) too for damage. Replace the horizontal scan output transistor. Check the input voltage to LOT. If the voltage is absent check the feeder resistor; if any.

No power

the noise you hear is the RELAY circuit. the relay try to power up but they cant, because the oscillation circuit is defective thats why your power is not coming out! the main problem is the hot side section, the problem is the oscillation circuit.

High voltage shutdown. The high voltage has exceeded 33k and the unit goes immediately into safety shutdown. Check power supply regulation and horizontal circuits.

The TV was working, and then randomly just shut off and won't come back on. It still makes the click noise when i turn it on, but only once instead of two. The standby light keeps flashing four times....

Hello melanie Hi, in my experience as a TV technician, that would usually be a shorted part, the horizontal output transistor, that part powers the HIGH Voltage section. Very Lethal, the power supply detects this bad part which in turn makes the unit go in standby so as not to damage the TV much further. mMy advice is go seek a tv tech to repair the part.

Lines on screen

Can you take a picture of the screen and post it? It is not possible for both the horizontal and vertical stages to fail at the same time to produce a cross. A picture of the screen would help significantly.
