Most of these sets have a self check----if Green power light comes on for a few seconds and goes off on the front of the set press and hold both the menu and input (source) buttons at same time for at least 5 seconds and release both.

Power light will blink a two digit error code like 2 blinks, 2 blinks a pause and repeat it for a total of 5 times.

Let me know if you get a error code and what it is.

Unplugging power from the set clears the error code so if that has been done you will have to try to turn set on, let it fail and then do the self check again.

SOURCE: TV Won'T Turn On

A fuse is not your problem. this TV has a safty feture that when it senses a problem it cuts the power to prevent any fouther damage, when you un plug it the TV resets and it will turn on agian. I have the same TV Check the CRT light guns there are 3 of them. If one goes bad it will cause your problem.

SOURCE: Clicking sound!

The TV is on protect mode. The clicking sound is the protection switch that keep turning the TV off to prevent further damage, this happens when a fault had been detected.

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

Also ensure that the fault is not coming from a faulty receiver box sending bad signal, check if you get same problem with no receiver box or dvd connected.

If that does not work, and you keep having a flashing led on front of the TV, and tv turning off by itself after a while, that indicates a fault condition.

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

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 , startingthe flashing light.


If you are in situation one, then theTV 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.

Common faults that can occur are a blown capacitor on power board, a convergence IC has blown, or a fault on Digital board.

Check also the video cable or any external connection cable, if the cable is shorting, or the connector is bad, you can get same flashing state because of the video cable.


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.

I push the power button the power light come on i hear a click the the light goes back off what is wrong with my tv


Do the self check this model has:

Turn set on and when green power light goes out: press and hold both the Menu and Input buttons on the front of the set for at least 5 seconds and then release both buttons.

The power light will blink a two digit error code: most common one is 2 blinks, pause and 2 blinks---it will repeat the error code at least 5 times.

Let me know what you find--2,2 is the most common and may be a do it yourself repair.

Sylvania 6842THG won't turn on. the tv red light displays when you push the power button you hear a click and then 5 - 10 seconds it goes back off


I have been having the same issue. I unplug the TV for 10 minutes and it usually works fine. I moves all of my A/V plugs to a single power strip and that helped a lot. Since then, the TV went into protection mode only once in 2 weeks. Next, I will use a power strip that includes the cable protection.

I don't know why but this got my TV on.
I took off the back cover and found the source of the clicking.
Two blue plastic rectangular relays in the exact middle.
When I pushed the power button, I felt the top relay click, and I saw a flash from the bottom one. (they are right next to each other)
I took a hair dryer and placed it over the two relays for about 1 minute and tried the power.
It clicked only 4 times and then came on!!!!!!!!!
For some reason heat helps the relay.
If anyone is a tech and can explain this, please do.
Good luck!!!!
My tv is on and it didn't cost me anything.
I just can't turn it off now!!!
