Panasonic TV problem

subversive · 14-09-2012, 04:19

Hi,

Hoping there are some TV repairers on this forum.

I have a Panasonic tx-28ps12, its around 7 years old I think. Its a CRT TV.

Well I was watching a movie and it just turned off, I thought a fuse had blowned, etc..

What I have noticed, everytime I switch it on, it could come on and switch off again and the red light next to the "on" switch will flash.

I have disconnected all scart cables, etc

Can anyone shed some light on this?

(please don't say, dump it, get a new tv, that will happen, but I would like to fix this)

Nigel Goodwin · 14-09-2012, 08:54

Sorry, but a CRT TV is completely worthless - in perfect working order you would struggle to give it away.

The red light flashing is normally an error indication, it 'may' flash a certain number of times to indicate where the fault might lie.

If for some reason you want a CRT set?, there are thousands thrown out every week, even charity shops will rarely take them.

David (2) · 14-09-2012, 10:24

the charity shop has one, for £10.

ProDave · 14-09-2012, 11:53

My guess (because it suddenly shut down in use) is line output transformer. If so not worth even looking at it.

I did an exercise for a rental property a couple of weeks ago. The tenants wanted CHEAP televisions for each room so I got them 5 free CRT tv's to which they added cheap freeview boxes. A simple wanted ad on the local freecycle produced many offers of free CRT sets. One was a quite nice JVC 28" widescreen in perfect working order.

So just do the same, get another working one for free and take the broken one to the tip to be recycled.

DOH, I was hoping to get a few more years out of this.

Well, if anybody can help me, the light flashes 3 times.

I guess I will see if I can fix it, otherwise new tv it is...sods law it had to happen now and not around christmas...

Nigel Goodwin · 14-09-2012, 13:32

You need someone with access to the service manual, which will tell you what 3 flashes means (I couldn't find any sense about it on google).

ProDave · 14-09-2012, 13:41

You could always ask here. But you may not get a quick reply, as very few people bother repairing CRT sets now http://www.tv.quuq.org/forum/index.php?board=25.0

As others have pointed out it's not expensive to get a replacement CRT as people are giving them away so that may well be an easier alternative than fixing your one.

from this website, it seems the three flashes means a faulty fan. do they have fans??

I will open it up and see, for curiosity's sake. With the power disconnected of course.

I don't mind getting a replacement, but it seems the rest of the family are over the moon with joy, literally, as they wanted to buy a flat led tv.

I suspect some voodoo magic..lol

Like I said, I could find no sense on the internet - I saw that site, the reference to a fan is for a completely different model (not even a CRT set at all). There's little commonality across error codes, different models from the same manufacturer often use different codes.

I checked my few Panasonic manuals, I only have a TX28PN1, which doesn't appear to have error codes.

Thanks Nigel, looks like I will have to say fair well to my beloved TV..many a hours have I played halo and GTA on this....

Favourite on a TV of that age is failing electrolytics in the power supply. I don't know the set so I can't give you any further info, but a blanket replacement of all the large caps in that area usually pays off.

Sony and Panasonic 'usually' fitted better quality caps than the other manufacturers, so it's not that likely.

Also, capacitor failures don't generally give error codes (it's too catastrophic for that).

to be hnest Andy, I have no clue about TV's, if this was a PC, I could take it to pieces, but TV, not my field.

It just switches off when you turn it on and the light next to the power button flashes three times.

here is the model number. panasonic tx-28ps12

family have already started to give me list of tvs they like..lol...

I might just get a new one, too much hassle. I have the weekend to decide and see if I can find a solution.

Buy a new one - it will be far better than your old CRT.

Someone round here must have sold a LOT of Panasonic CRT's, because we get loads coming in for disposal (many of which are fully working).

jasonjimbob · 14-09-2012, 20:33

I got a 32 inch Panasonic CRT TV with Pro-Logic sound, and I noticed a problem with mine too, only after switch on, the picture flashes a red colour, and after a couple of minutes returns to normal. Does this mean that the Colour Tube, is on it's way out? I have had this set for about 9 years.

Yet the British Heart Foundation shop near here has a whole shelf full of them at around £40 each and they sell.

They are doing amazingly well then - charity shops round here won't even accept them, as they can't sell them.

We can't even give them away

Maybe the OP needs a nice drive up to Derbyshire?

For goodness sake Subversive take note of the advice given you. Your CRT TV isn't worth repairing ! It's probably a fire risk by now - Flatscreen TVs - especially Digital and now HD are incredibly good value and give you outstanding picture quality -
Do your eyes a favour and get one (no less tha 42" !!!).

P.S. Oh yes and at 0414 hrs you should be in bed fast asleep !

You realise you can still get a shock from a disconnected CRT TV don't you?

No you are not.

I "only" have a 32" LCD, but when I installed that 28" CRT for someone a couple of weeks back, I was shocked at how tiny the picture looked.
