Re: Panasonic TX-P42S30B - 6 blinks

Good morning,
Many thanks for replying and the useful links. The one is Caerphilly is not too far away however no distant cousin , theres a few of us here in Wales.
I will give them a call later.
As mentioned in my ealier post I dont think I have the dexterity to make the repair/replacement myself but probably OK to remove the board and send off.
I came across this service yesterday:

Re: Panasonic TX-P42S30B - 6 blinks

were you able to test C842 as indicated in the red warning print: QUOTE "Please do check resistance across C842 (it's visible on second picture), if resistance is zero or close to zero your board have got faulty at least one buffer chip and then I will not issue full refund" It is not clear what the repair is he's talking about, if its just 8 washers you can get those for a buck or so at the hardware, He might be saying if you have a bad buffer chip then it's no deal, may want to contact them and see exactly what the repair consists of.

Re: Panasonic TX-P42S30B - 6 blinks

did you try the simple test in link, post #100?

[nomoresonys]

Re: Panasonic TX-P42S30B - 6 blinks

this might be a better bet, looks to be the same part number TNPA5349, see if it matches yours, maybe contact the seller and see if they know if it will work for your particular tv, hard to tell what the shipping is, it may have calculated the shipping to the U.S. not sure, will probably be different to the U.K.: https://www.ebay.co.uk/itm/255428487...Bk9SR-r5y6v_YA

One of the local members on this forum may have that board and can beat the price? never know.

Re: Panasonic TX-P42S30B - 6 blinks

not a fan of getting anything from china, they burn HUGE amounts of coal unrestricted and unfiltered from what I read and saw on the news and youtube, but there's aliexpress: https://www.aliexpress.com/w/wholesale-tnpa5349.html

I did make sure that my last oil filter wasn't made in china, so that's a good start.

Re: Panasonic TX-P42S30B - 6 blinks

Many thanks for the replies. Shipping from anywhere other than the UK is prohibitive and to be honest I can buy another used 42" TV for about the £50 but thats not the point, its about avoiding waste and land fill and maximising utilisation.
Will have a go at the C842 test and let you know.
I did talk to a couple of reasonably local TV repairers withiout any joy most want £50 just to look at it and dissmiss the fault diagnosis that I've come to with the valid help of his forum.

The Tronic bay link is very interesting, I havn't seen that before..
Stand by

Re: Panasonic TX-P42S30B - 6 blinks

I understand, I don't like adding to the landfill either, worse thing about plasmas to me is the weight, about 5 times heavier than an led tv and they use a whole lot more electricity, I don't know whats worse, adding to landfill or using the extra power.

Re: Panasonic TX-P42S30B - 6 blinks

No, we don't bury electronics in the UK nowadays, it wouldn't end up in landfill.

[nomoresonys]

Re: Panasonic TX-P42S30B - 6 blinks

ok, you dont bury electronics in the UK nowadays, thanks for sharing. we also NEVER send any electronics to the landfill in the U.S.A. we have hired landfill police, they were available since joe biden and nancy pelosi DEFUNDED the police:

Good evening again,
Found C842 after 1/2 hour of searching.
How do I test this?
The most obvious place (to me) is the contact at about 3 oclock on the 'C842 bottom' image as attached. I get about 145K ohms between that and ground/chasis.

I did have a look at the Shop Jimmy video but this exact model is not listed.....

On going help appreciated.

Re: Panasonic TX-P42S30B - 6 blinks

the only way I know is to remove the board and check across the 2 legs of the capacitor from the soldered side, if you do, ALWAYS put ALL the screws back in securely before turning tv on, they are important to grounding and NONE should be left loose or out, it can short out the board.

[nomoresonys]

Re: Panasonic TX-P42S30B - 6 blinks

good policy to leave the tv unplugged for a few hours before removing boards and be careful what you touch, it can hold a charge for quite a while.

[nomoresonys]

Re: Panasonic TX-P42S30B - 6 blinks

I believe that test is to determine if the buffer chips are ok, it looks to me that the ad you referred to, they are trying to sell 8 washers, might want to steer clear of that one.

Re: Panasonic TX-P42S30B - 6 blinks

now in this same video as in post#100, see how he unhooks some cables then tries it? thats how he determined which board is defective: https://www.youtube.com/watch?v=GFE14ElXz7g

[Mr Williams]

Re: Panasonic TX-P42S30B - 6 blinks

Thanks for that.
Just found this one as well and seems a little more engaged with customer so may give them a call.

Re: Panasonic TX-P42S30B - 6 blinks

ok, now the question is does he mean that he can only fix it if it has the exact 7 flashes, or can there be 6 or 4 etc?

[nomoresonys]

Re: Panasonic TX-P42S30B - 6 blinks

yes, maybe call or email them and see if they deal with the number of flashes that you have.
