TV won't turn on

Rix20601-
how hard is it to repair the high voltage board? i'm hoping to locate a fuse somewhere, but i fear those days are long gone.

my tv won't turn on either.

My TV won't power on either with the remote or with the manual power on. I hear a clicking noise and it appears that the TV is turning on and off. i bought this t.v sharp 29" model 29l-fg1sf from dubai, u.a.e, using it in india from 12th feb 2007 today is its 4th morning since the time i started using it...it is showing the same symptoms what you allhave mentioned above...i don`t know what to do??? can any technician help me...

Guess what, my samsung slimfit tv wont turn on too, press the button and theres a slight clicking noise, just doesn't come on

Sounds to me like there could be a fault with all the tv's they made, but i have rang comet where i bought it from and as expected as it has ran out of standard 1 yr guarantee, they wont do anything unless i pay £150 for engineer to come out!

My TV won't power on either with the remote or with the manual power on. I hear a clicking noise and it appears that the TV is turning on and off. After several times it stops. Never actually see a picture.

hi i have just got a 37" lccd and i wont turn on for s*#t it id digihome dose any 1 nw ho to fix this
plz

I have the same issue with my emerson model 2704. While inspecting the circuit board i noted that the HV transformer was set incorrectly at the factory cracking the circuit board. A fix was applied using solder to close the broken ciruit and it had fell off. I resoldered the circuit and it works fine now.

Hello everyone!!

I've had thesame problem with my Sumsung TV set I've contacted the technician hes said that it'll cost me about $200 to get my tv back alive!!!! So I've decided to check it myself and see what's up it was the fuse I've replaced it with a new one bing my tv is working like brand new it costed me $3.14 wow try it you'll see :) good luck!

Unfortunately, this is not a solution. I bought the same set in Jan. of 04 and I have the same symptom that first occured on 11/18
in the morning. After numerous attemps to power on the set, it statrted working again. It worked for about a week with no other issues, until 11/24 when it started doing the same thing again. I unplugged set from the wall for 5 days, tried again and it worked fine for two hours. Then the screen went blank, audio OK. Turned set off and it hasn't worked since. :>( Is the set going to turn into a money sucking peice of electronics? I'd be interested to hear from mpbbuzz if he was able to get the set repaired.

I have had several TVs of various makes and models whose fault is that they try to turn on but can't.

I still have one in my closet from years ago! Now, my little GE portable has crapped out, too! We are not amused!

In my opinion, it is a fault that is purposely designed into the TVs by the manufacturers!

They know that the cost of repair is too prohibitive and most people will just junk their old TV for a new one.

I think it is dispicable! But, that's our consumer society for you.

well i got the same prob but by looking closly at the fuse u see a be be looking wire on each end connecting a thiner wire im gonna try a bugger fuse low amperage aka "thin fuse wire" could be the prob hey its worth a try

first thing to do is to test the flyback testing flyback has a service charge (P50) and if the flyback is o.k the problem of your unit is in the Horizontal output. i suggest to change it. a leaky H.transistor is a part which is located HV section wich let the unit turning on.

this is the same problem i'm having so this is obviously not a solution but i didn't know how to ask what it would actually mean to get this high voltage section fixed and how much does something like that cost. is it possible to just buy parts and use common sense to fix or do u really have to take it into a shop... thanks

You weren't listening to his question. He already was told by a technition that the set had a problem with the transformer. You simply reiterated what he already had been told. His question was whether anyone KNEW OF A CHEAPER ALTERNATIVE solurtion.

By the way my Tv has just begun having the same problem,. It must be a common fault. Typical Sony!!!

**** my balls

"An idea from the origin of the problem"

I have the same problem on a 25 inches T.V. What I remember before the problem began is that T.V. had a problem with the Sleep function, the problem was that once you had activated the sleep button, it was not possible to cancel the function until next time the T.V. was turned off and on again, but never with the ciclic function Sleep that normally gives you determinated options until it gets cancelated.
With te time it got worst because if the button Sleep was pressed the function only was presenting the Red label that means that you only have a minute before i tuns off.
My supposition is that the function sleep is having an effect of turning off the T.V. as soon as you tun it on.
Now I am trying to contact a technician to fix the problem I hope he can cancel the Sleep function and fix it.

I hope it helps.

Capacitors in the power supply can cause this fault if you can replace them it may cure the problem. I had the same problem and changed it myself and i have never done this sort of thing before. The Capacitor cost only £2.10 in total and guess what? my TV's working!!!!!!!!

The noise is probably the power supply in hicup mode or safety mode, that's what happens when a fault develops in the set which loads the power supply down. All you have to do is get a multi meter and go round measuring things like Resistance to earth from collector of line out transistor this should be at least 10kohm , then measure the various diodes that can be found in the power supply... hope this helps.

Open it up and look at the capaciters near where the power plug attaches to the circuit board. If any of them have a bulgeing or pushed out top it needs to be replaced. get the numbers off the side and get new ones from radio shack, just a buck or two a piece. You'll need to solder to do this.

all you need to do is buy a brand new tv and trade the parts then bring the tv back the next day and say my brothers friend is giving me a tv so you want to bring it back it worked for me ok so it should for you ok you get your money back and a good tv!!

how to change high power transformer

I have same problem with a samsung. it just shut off and now it will not turn back on. You hear a clicking noise and a red power button flash three times and the screen kinda flickers like it is trying to turn on, but never actually does.1 year and two months just over the warnty.

take of the front speaker cover then shake it a little bit to make sure theres not a short then try.

You guys are lucky, I've had mine for 6 months. We shut it off last night, and that was that. Won't come back on!

I have the same problem but with a Toshiba. For a while i had this problem every morning but if i unplugged it and left it alone for a few hours came back and plugged it back in it would work fine until tomorrow, but today thats not even working. any help would be very much appreciated.

rix20601,
Thanks for the soulution. I bought the same TV and it has the same exact problem as this. my kid turned it on and off until it wouldn't turn on anymore. I thought the front panel block was enabled but apparently it wasn't. Anyway, your suggestion only helps confirm what a few people I've talked to havve said. Thanks again -Mike

After about two years of continual stable use, I too developed the same problem. It occured after a lack of use for months, damp/dusty environment = clicking sound when trying to turn on tv. Repeated attempts to turn it on would eventually work. Fortunately in my case it developed over time and just got worse after each extended lack of use, until eventually it wouldn't turn on ever, it would only click. Using your information, I removed it from the damp environment, opened the back and used compresed air to clean the inside components. Initially no change in status. Repeated attempts to turn it on, however, did produce results. It is now day two and the problem is still there, although it is getting better. The longer it is on and more it is used the more stable it is becoming. I currently believe that one of the components collects moisture and the heat of use/attempted use, dries the area of the short. However, I also believe that the component retains more moisture than just in that area and that it is improving with more use due to a cumulative drying process.

It Would be cheaper if you order the Flyback transformer youself and replace it yourself cost would be 60bucks

I had the same issue with mine. It was the transistor, resistor and a cap located where the A/C input is on the board. The "power on" circuit I guess. Cost was about $110

I have the same problem with my TV. It's like it'll turn on but then it shuts off right away and I never see the picture. Sometimes if I manually press the power button over and over (I mean OVER and OVER) it'll turn on but the past couple days that hasn't worked. I think it's time to throw it out (I've had mine for quite a few years and it's more trouble than it's worth for a 13 inch TV).
