G'Day!

Unfortunately, what you're describing is a repair issue. You won't be able to address the problem with troubleshooting. There is a part inside the TV that needs to be replaced. If you're under warranty, this will cost you nothing. If you're not under warranty the cost will likely be a minimum of $200 parts and labor. However, be warned that the cost could be considerably higher.


I hope I've provided you useful assistance and that this information allows you to make an informed decision as to how to proceed from here. Please be sure to vote on my response. I hope I've earned a good rating from you today.

Please post a comment if you need additional assistance so that I can help you further.

Does the system have an amplifier ?
Circuit/System Verification
Radio ON, Rear Seat Audio (RSA) OFF (if equipped), adjust the fade and balance controls on the radio to test all four channels individually. Each of the four channels should produce clear and even sound.
Without Amplifier Radio ON, verify clear audio is heard from each audio speaker.

If audio is inoperative from all speakers, replace the radio.

Overheating


Hi,

It probably has a fault.But try this.Disconnect all speakers and inputs and try again.If that works reconnect the speakers A PAIR AT a Time.That should lead to the fault.If that still shuts down.

the set is going into protection mode. This is caused when ever one of the many sections of the tv has a shorted circuit. The increase in current is detected by the protection circuit and it flies into action by turning OFF the ON relay.


Most often, but not always, it is either the high voltage section or one of the deflection amplifiers. But can be the power supply, the audio amplifier or voltage regulators, etc.

Goodluck..

I have a Samsung HLT5076SX/XAA with power up to picture problems.


Im going to guess that you have crackling and hissing noises, as well as the infamous "click" then nothing when you try to start the tv. This is caused by circuit failure on the main board, which powers up the main inverter to charge the screen. ( a high voltage thing that makes the picture come on) when the board cannot provide a high enough starting voltage, the symptoms you described start happening. It is not an easy fix, and will probably set you back a couple hundred dollars or so to fix. I hope the best for you

TV pops, then no picture or sound


Trintitron were very state of the art when they came out in the 1960s. The Sony company stopped production of the newer version, flat screen in 2008 of the trintitron. Popping noises aren't a good sign. You can try resetting it to factory default settings. Try to have the power on to tv, then, hold down the reset button on the REMOTE CONTROL- next on the tv PRESS THE POWER BUTTON ON=IF AND WHEN THE TV WILL TURN ITSELF OFF AND ON AGAIN, THEN YOU CAN RELEASE THE RESET BUTTON. Unless it This noise is caused by the expansion and contraction of the cabinet during warm up and cool down of the lamp in the optical block of the television. This is normal operation. But you having no picture, this could be your power circuit is going out. You can get it fixed, but if it is an older tv you may want to upgrade to an LCD, HD, or even a plasma. They have really nice flat screen HD TV now that are not too expensive. But if you are pleased with this tv it might be worth getting it fixed.

No picture or audio.power light blink on once and turns off


The real deal here is the protection circuit has activated. This is caused whenever an excessive amount of current is being drawn from the main power supply. Upon detection of same, it immediately takes over the power management of the set and shuts it down. The clicking sound you hear is the ON relay turning on the set, but immediately the power mangement system shuts it OFF. You should hear two clicks, but they may be so close together that it sounds like one click.

This set is getting rather ancient and I would not recommend you spend much money on it for this reason: It is highly likely that once the set if repaired that another failure would occur. This is because of the law of averages; the first failure is often followed by another failure from anywhere within the set.

Rca 27410tyx1 will not shut off


Sounds like trouble in the standby/power up circuit. have you tried unplugging the TV for a half hour and seeing what happens? It might start up but I think this problem won't go away. If you heard a high pitched buzzing it sounds like a problem in the high voltage not letting the start up circuit work. threy are related. The start up circuit waits for the high voltage to stablize and then switches it on.

TV turns on can hear sound then shuts down.


Did you check the high voltage transformer and the high voltage splitter (distributor). RCA HVT is known for going bad. i have the part number for both if needed. 5520-559-5774 john

Picture goes dead after 5-10 minutes


You may have a loose solder joint causing this problem. If you can take it apart, you mihgt try spraying circuit cooler in various parts of the circuit but NOT in the high voltage or horizontal circuits.YOU MAY CAUSE AN ARC OR A COMPONENT TO SHORT SINCE THE SET HAS TO BE IN OPERATION WHEN YOU SPRAY. If you hit the bad connection the picture will come back on. When the picture zaps to the middle of the screen, is there just a bright line? If so, then you have a loose connection or a temperature problem in the vertical circuit. Stargazer

No picture or sound


It sounds more like a shut down circuit problem if you can feel static from the face of the picture tube after it tries to start up. There are several things that can trigger a shut down condition on TV's. For instance, if there is no vertical deflection signal present, the set may shutdown to prevent a permanent line being burnt across the front of the tube. If the power supply wasn't regulating the B+ voltage properly, it would shutdown to prevent damage in the horizontal sweep section. Or if the horizontal deflection circuit was defective and allowing the high voltage to climb too high (say above 33,000 volts) then the sensing circuit would trigger a shutdown event. If any of the above sounds like gibberish to you then you will need to take the set to a professional for repair.
