Hi.

The set is expecting a pin number to be inserted.

If you dont know or cant remember pin do this.

USE REMOTE CONTROL AND BRING T.V OUT OF STANDBY,

SCREEN REQUESTS PIN CODE,

PRESS STANDBY, PRESS NO. 7 BUTTON FOR 6 SECONDS, THEN IMMEDIATELY PRESS STANDBY (THERE MUST BE NO DELAY BETWEEN LAST ACTIONS).

Do this to the letter it should sort out your problem.

try 0000 reset

Other wise
This is how its done but you will need A repair shop to do it.

Place set in to protect by entering any sequence of numbers 3 times,
Connect a 390ohm resistor between w129 (ground) and pin 56 of the micro,
Press button 7 on the remote for a minimum of 6 secs.
And thats it unlocked.
Sorry its not a simple fix.

Audio static when using any power switches in house


You could try a power strip that has voltage spike protection in it, but to tell you the truth, TVs and other electronic devices are supposed to accept such interference without malfunctioning.

Both of my tv's died yesterday. My apex wont turn on anymore an the panasonic has no picture. Whats wrong.


As an electrician, when someone loses more then 1 item of electronics in 1 day, its almost
always traceable to a nearby lightning strike, accompanied by a lack of surge protection for
the VCR/TV/Computer/Stereo/uninsured valuable electronic item/XBOX 360. Surge protection can
be provided by the consumer at the power strip (a good one with builtin protection and a
warranty costs $20, whereas a zero-protection 4-outlet or 6-outlet power strip will cost $4-$5).
Your electrician can provide whole-house protection, or per-circuit protection at
the breaker box, where a GFCI breaker (or better, an AFCI breaker) can be installed.
GFCI = ground fault circuit interruptor
AFCI = Arc fault circuit interruptor
Lightning protection is especially important in Florida, which is the "lightning capital of the world."
I've never found a good solution to lightning-fried electronics (random power supply components are destroyed), other than renters insurance or homeowners insurance.
If desperate, you could try replacing the entire power supply as a module, but even this provides
no guarantee of a fix - lightning damage can extend beyond the power supply.
When traveling, I will always unplug everything before I leave (except the security system),
and also turn off the breakers to unneeded house circuits (which kills the wall switches that
control interior lighting - forcing a burglar to use their flashlight instead of interior lighting)
which is the least convenient lightning protection, but highly effective, and cheap (free).

Is there a power fuse in this tv. sony 32" 1998 trinitron. Had great color, picture & sound. Will not turn on/no power.


There are fuses in most TV's... and in some cases, it's nothing but the fuse. BUT, the fuses are there to protect the circuits... so unless you know that there is nothing wrong with the TV, you shouldn't simply replace the fuse and plug it back in. However, if the TV is an older TV and it's either fix it by replacing the fuse or get rid of the TV... then I'd certainly take out the screws and check the fuses in the TV. But many times the fuse blows to protect it when something else fails... so if you find a blown fuse, look around for other signs.

WORKING ON ELECTRONICS should be done by professionals!! Proceed at your own risk!

2 tv's when I try to cut them on they make a clicking noise


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.

If you want to DIY you find parts here, a common fault is PSU, but part must be tested before replacement.

Power flashing on and off


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.

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.

Problems with JVC AV-32WR4EK


This could denote a power supply problem. or overcurrent protection due to a component going bad. If you do not have electronics experience, "DO NOT TRY TO WROK ON THIS SET" people have been seriously hurt trying to repair TV without knowing the basics of electronics. If this is a power supply problem it may be the HV supply and the switching power supply (IVHT based) or the low voltage starter supply. In both cases I would advise you taking it to the shop for repairs.
