    Hi, I have the same problem with my tx-sv535. Their is something wrong with the outputs and my electronic's guy could not figure out what to do. He tried everything he could think of without tearing the whole thing apart. What can I do, other than to throw it way?

    Same problem here too.The face place shows PROTECT. What is protect mode? I could not find any definition of it.

  • Anjuliam Mar 08, 2008

    I am locked in Protect mode and did the manual reset (hold down video 1 and press off) however the problem remains.



    Any help would be appreciated.

You tried reset on front panel? you hold down video 1 and then also press power off. the panel says "clear", then start up again.

Protection mode


Try tapping it on the top or sides with your hand or fist, I was told this buy a body of mine, That has been a (Electronic) Tech for over 20 years now, Tap it fairly hard,It has work for me with recievers And amps to get them out of the (Protection mode.What causes them to go into (Protect) Is a short in a speaker lead or the speaker wire come disconected some how,Or there could of been a power surge.

TV shuts of and turns back on all the time


The issue your having comes to mind as a bad power board, What happens over time is the electrolytic capacitors inside these Tv's bulge or just become un-usable.

Many power supplies are plagued by poor electronics components such as these and thus you have a TV with a power issue.

The best bet here is to purchase a new power board or locate the defective component and replace it.

Many cases this Tv would end up beside the dumpster awaiting the next pickup date witch pollutes the environment and creates a huge in-pact.

A repair shop would be a option but you will end up with a bill of $200-$400 bucks just for a power board change out!

What a TV tech would do is bring this in and test it with other parts. A TV tech is basically a person that graduated from some post- graduate or trade school and would charge you big money to simply switch out a power supply.

Many people like myself and others have been around the electronics repair era where we fix these broken items for Penny's on a dollar.
Do this at your own risk

If you steer to the internet with this and know basic soldering skills and electronics precautions I would suggest you dig into the unit at your own risk and purchase the components that are actually effected.

You can watch my you tube video on how I basically pulled a power board out of a LCD monitor and replaced its cap's. You can aslo go to my tips on how to search for bad caps and replace them using basic soldering skill.

My receiver is in protect mode..what does that mean


See reasons for protect mode on onkyo site.
Most likely the speaker wires are shorting or are reverse polarity. see connection diagram.

I have a problem with my TX-SV535, there is no sound when i putt Dolby Surround. The test is also no sound. I have checked al cables and connectors.


If you are getting standard stereo sound but not when engaging any surround option, then the problem is centered around the digital processing section. In standard stereo mode, the processing is bypassed. On some units this too would yield no sound, but with your model, the bypass is external to the processing section. This problem can be as simple as a bad voltage regulator on the processing board to a more elaborate problem within the processing circuitry itself. Without actuall seeing the unit and testing internally, I can not state for sure. This is a decent receiver and is worth the cost of a detailed repair estimate. Get one and report the results here. We should be able to guide you through the actual repair.

No sound from zenith dvt412 stuck in bypass mode..how to override?


this is a protection circuit.
When bypass mode then it means that something in the power supply module has failed and the unit then goes into protection mode to protect the board components.
Your surround sound need service from a qualified tech. No other remedy.

Tv has got stuck on standby mode


If the TV goes off completely, then is usually a faulty power board.

If the TV goes in standby, then it is in protection mode.

Ensure also that the fault is not coming from a faulty receiver box sending
bad signal, check if you get same problem on DVD with no receiver box
connected.

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

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

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 , starting the flashing light.

If you are in situation one, then the TV 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.

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.

On LCD Pay particular attention at inverter and power board, power board can be inspected looking for bulged or leaking capacitors, then tested with a multimeter. The inverter is more difficult to test , there is need to read voltages, should be done by a tech. Also the LCD controller board can cause same problem

On Plasma, test Sustain (Ysus/Zsus) / Buffer boards , cables to plasma, digital board and power board.

On Rear Projection : check lamp, lamp ballast, power board, and convergence.

On CRT TVs, check ballast , flyback transformer, CRT, Tuner, Convergence.
