Hi,
"23" is an error for "horizontal deflection failure". When this circuitry gone bad the unit will not power up. This is not an easy fix because you have to check the horizontal drive from IC2V00. This signal flows to a lots of parts like the transistors (Q2V40,Q5A40,Q5A33,Q5A39,Q5A32,Q5A31,Q5A37,Q5A01), resistors, and capacitors which will drive to have a complete circuit to the FBT.
B+ supply line is also going to check for an open circuit.
To determine where the fault came from, the unit will go to series of resistance and actual voltage measurement. It needs a technical knowledge in this circuitry.
I would advice you to look for a qualified TV Technician to isolate the faulty parts.
Also, check if your unit is still under warranty/extended warranty period, avail it because the manufacturer will fix it for free.
Hope I helped you.
Have a nice day!
Thanks for using Fixya.

above is your service and repair manual, below is your owners manual.

OK well what has happened i suspect, is that your set has been "Spiked" from a power disturbance, and this has damaged either the PSU, or an internal high voltage component, or both, and now, the Protection Circuitry in the SMPS unit, is "Sensing" a potential "Catastrophic fault", that may cause a fire an explosion or both, and accordingly the set MUST be shut down, so the protection circuitry does exactly that.
Your best bet, is to contact a local or head office of the TV's manufacturer, and ask them for a referral to an authorised servicing center. When contact is made with them, ask for a "Quote" for the repair, before allowing any repair work to be undertaken. This then at least will give you an idea as to costings and you can then make an informed decision as to repair or replace, as often these days i find in my shop anyway, many repairs can be very expensive, and often it would be better putting any monies that would have been spent on repair towards a NEW unit with a warranty.

However if you really wish to DIY, then I have supplied the service manual, so you can begin troubleshooting, as usual always start at the Power supply and check voltages here first as if the voltages aren't correct here, then nowhere else can be...follow any potential incorrect voltage to it's fault.

Ours did exactly the same at about the same age. JS

unplug it for a couple of days or find the battery on the board

Hello

The problem with your tv is called CONVERGENCE... Its a fancy name that says one or more of the guns is not firing at the right spot.

In your owners manual there will be a page about how to reset the convergence, that will make you line them back up again. Sometimes (and I fear this in your case) the chips go bad and you cant make the tv come back in to convergence. Often when people say it looks like 3d this is the case. If you find that you cant get your set back in to convergence there are several places on the internet that sell repair kits. Repairing the tv will often require a little soldering but often the results of your labor will be a stunning picture for years to come.

Google tv repair kits and put your model number in.

Here is a site I use as an example. As you can see it is in the UK so no one can claim I am trying to pick one place over another...

Put that will let you see what the kits look like.

I hope this helps you

Tools and skills must have.Tools,a soldering iron,desoldering pump or desoldering braids,solders?Skills,must know how to do the basic soldering?Tries websites like Tvrepairworld.com,Tvrepairkits.com to buy the convergence kit to repair it ur self.A kit also came with a instructional DVD disc.The shop,will cost u $300-350 for parts and labors.

This model has what is called the "option" menu which is a hard reset of the set. It returns the set to the condition it was when new in the box---on air band on channel 3.

What is reason you want to do the reset? I can tell you how if a good reason.

If this helped you rate this solution as very helpful as I do this here for free and respond with a comment here.

This tv have a problems known as a conveegence problems,it dead.The tv convergence board must have it 2 STK convergence ICS and some or all it resistors to be replaced to solved the convergence problems.The shop will cost u $300-350 for parts and labors.

Given the age of this tv you would need to find a parts donor to locate a screen. If one is not available then you may want to consider selling the tv for parts.
Thank you,

You have a problem in the horizontal deflection board. It will start with bad capacitors and poor grounds. You may also have a high voltage switching transistor along with one or two horizontal transistors that are bad. I would certainly start here. The convergence board occasionally will do this, but not in this case. Ask a TV tech to check the the deflection board. And mention it may also be a bad Vertical IC is shutting the TV down as well. You are now armed to speak with a TV Repairman. Good Luck and thanks for asking!

buttons on the front are likely bad. use this to help find the plug to unhook and hopefully it will work with the remote still

Let me know if I can be of further assistance.

Try website like Tvrepairworld.com to buy a refurbish DM power board for the replacement or parts.U know soldering?Buy capacitors for repalcement.

looks like u have a bad switch at the control panel . what u can do is take the fron speakers grill off and unpluge the front panel and turn u tv on with the remote control it should work

Try to turn the contrast down. It can really help out a lot. If this is not working look up your tv's best settings. CNET.com has some great settings under the forums.

If all else fails but a calibration dvd and go thru the settings. Some dreamworks and disney dvds even have them right under the disc extras. Hope I could help!

by the way, remember to cut some of the light in your room if it is well lit. It will help make the picture look better as your eyes can distiguse the light and darks better

Your television is done, nothing you can do. Inside the Anode which is on top of each Cathode Ray Tube, there is PTV Coolant which is higly toxic and corrosive. It is clear in color and if it gets on the boards there is nothing you can do to fix it.

proply the fuse

no, if blink code the problem is in the TV set--cable will not cause this type of trouble
