Question about Televison & Video

1 Answer

Grundig T55-1010 TV says protected, this happened after a power failure. It did it once before in 2001 and it cost £15 at Currys to get it reset, as the tv only cost £100 nearly 7 years ago, its probably not worth £15 now. How on earth do we reset it, we didn't set a code or anything when we bought it and Currys technician didn't tell us what he had done, he disappeared into a back room and came back a couple of minutes later with an invoice. Please help, Coronation Street is on tonight and the portable tv has a bad picture on it. Please Please help Sue Hutch

I have a Grundig XENTIA 82 FLAT MFW 82-430/8 TV, everytime i turn it on i get a blue screen & the child lock nb to fill in, so i have to type the nb 7038580 to watch tv... how can i cancel this koz...


If this is happening on all the channels I think you will need a total reset. If so open menu and check the settings for child lock when you manually tune. An option is to reset the channels once again after the lock is opened. Choose a new channel scan to reset the memory. However if the lock seems to be only on specified channels you can open the settings of the channel and unlock on the menu.

Hi i have a grundig gu22dvd the power supply keeps turning off can i buy a new poers lead and transformer


helen366, if unit continues to do same thing, I suggest you contact Grundig for warranty service to put it right again!!! You must tell them that it should not have premature failure of the internal "switch-mode-power-supply" and they should replace the unit with new or refurbished same model free of charge.

Most but not all TVs have a "protect mode" to protect against electrical damage to the delicate circuit systems when a failure is sensed,usually this means the TV will shut down when further damage could occur when sensing these problems, it is a safety and could save you from the TV being damaged beyond sensable repair costing to much to put into the set. Try unplugging the TV for 30 minutes or longer then restore power to it and it may go to factory defaults and operate as normal, or seem normal until the failure is sensed once again, then you will need to have a tech.out to perform service to repair the problem. Good luck and Merry Christmas!

Tv wont come on. standby light is read but nothing happens when the power button is turned on


Normally, this happens when the TV detects a bad circuit board and goes into " Protection Mode ". Most likely the TV has a power supply related problem. It's possible that it maybe a bad capacitor or transformer on the power supply board. But, I can't say it's 100% the problem because I can't actually look at the tv over the internet. I can only make guesses with the symptoms.

You have a few choices:

1. You can try leaving the TV unplugged for 30 - 45 minutes so the TV can discharge and reset itself.
2. If by chance the TV is still under warranty, go that route.

3. If you have some electronic experience, if you can find and purchase a Service Manual over the internet; It will help you diagnose the source of the problem and fix it by soldering in the new part. The Service Manual will give you circuit diagrams, test points, and part# lists.Usually, cost under $20. And most cases the new part cost less than $15.

4. Pay a TV shop to do the repairs. It maybe costly, but get an estimate of how much they will charge. That way you can decide if it worth repairing or replacing the whole TV.


I hope I shed some light on the subject for you.

My Philips 32PFL5403D LCD TV does not turn on and blinks 6


Normally, this happens when the TV detects a bad circuit board and goes into " Protection Mode ". The blinking red light should be a error trouble code. I don't have the Service Manual on hand for your model number to tell you what the code means. Most likely the TV has a power supply related problem.

There is a good chance that the failure is in the main power supply. 
A second chance is that the set is protecting itself from a failure after the supply; this is more likely to occur in the horizontal section where the highest power consumption occurs. 
If the failure is in the supply, it could be a fairly reasonable cost repair. If in the horizontal section, depending on whether the failure is limited to a $10 horizontal output transistor or a bad flyback transformer. The transformer should still be available but with markup, shipping and installation, the cost could exceed the $100 US mark.
Generally, I have been recommending folks repair their old standard definition sets, buy a converter box for digital TV, and not dispose of them since the flat panel sets are dying like flies, often just after the warranty expires.   This would at least provide some kind of set when the expensive LCD or plasma sets go belly up.

Protect


The protect message indicates that a problem has been detected in the final output stage of the amplifier. The most common failure parts are the output transistors. Plan on a parts cost between $15-$40. Add in the local labor rate for the total repair cost.

Will not power on


Unplug the power cord and let is stay OFF for about 2 or 3 hours. Then power it up again and see what happens. This is what we call hard reset. It works to bring the set back to life in about 25% of occasions.

If it does not help after the hard reset above then it will need to be looked at by a tech who knows how to navigate around a protection failure. The reason it won't come back on is because the protection circuit (and electronic, intelligent fuse) has detected a severe shorted condition somewhere within the set. It is usually the main power supply, the high voltage section or one of the deflection amplifiers. But, can be from other sections within the tv. That is why you must have some diagnosis completed to find the problem.

Another cause, less frequent on this class of tv, is from bad or cold colder joints. You can check for this by just whacking the set vigorously with your hand or fist in an attempt to dislodge a cold solder joint. This may help, but don't hold your breath. If it does, look up and thank the stars in the heavens for smiling down upon you.
                            or

A turnoff as you describe is generally caused from current overload which sends the set into protection mode.

This is a very common occurrence.

FIRST: Give it a hard reset. Unplug the tv for a couple of hours, then try it again.

SECOND: Whack it good with your hand or fist. Doing so will often reactivate a bad joint, connector or cold solder.

THIRD: It may need servicing if the above two remedies bring nothing to the for.

The cause is often a failure in the power supply, high voltage or deflection amplifiers. It is never from the same cause as other sets. Cost of repair can be from $100 to $400, depending on the final diagnosis.

                      or you may try this

Well, the reset procedure would be to unplug power for a few hours and then power it back up.

Try wiggling the power cord at the end that plugs into the wall and the end that is attached to the tv. Sometimes the wire inside the molded ends goes open circuit from being crimped too hard during manufacture.

But, if still no power: Since there is no indication of power at all when you plug it in it is most likely a major power supply failure. Such repairs usually run over $100. Could be much more than that.

A set of this size and age is marginal. The rule of thumb would be if the cost of repair is more than half the cost of its replacement it may not be a wise investment.

Statistically it has been found that once a tv starts failing, even the first time, the likelyhood of another failure soon after is very high. Even for Panasonic which is generally a good model

Let me know if you have further thoughts.

Good Luck
