Dead plasma TV (mainboard), resuscitation possible?

[weary]

A power surge fried my washing machine and my Panasonic plasma TV a couple of weeks ago. The washing machine is now repaired (replaced a fried circuit board), but the plasma TV can not be repaired by Panasonic, because the failed part (a mainboard, also called 'A-board') is not manufactured or available anymore.

Since this TV cost 100,000 baht, and since the actual plasma panel is still functional, and the picture quality was still great up until the day it died, it seems a shame to just throw it away. If worse comes to worst, I will though.

But I've seen used mainboards for other plasmas available on eBay, and I wonder whether some dusty little repair shop or recycling place in Bangkok might actually sit on a functional mainboard for this model.

 

So my question is, does anyone have any ideas where I might be able to find a mainboard? The other option would be, a place that could troubleshoot and repair the mainboard using smaller parts.

The TV model name is TH-50PY800MT. Manufactured in 2008... so not exactly the newest TV on the block.

I've already googled around a fair bit, and found out that unfortunately, equivalent Panasonic plasma TV models in other world regions (EU, US, UK) have a different configuration of input ports on their mainboards, so those mainboards won't work.

I'm in Chiang Mai by the way, so I can't just pop out the door in Bangkok and look.

There is actually a good possibility that the "equivalent model" boards will work, you just don't get the same inputs, but of course, they may not.

 

Ebay may well be your friend, keep looking.

 

Search on the actual board part number (on the board) rather than the TV model.

 

Try Amorn Service, in reality if they can't fix it it is, unfortunately, scrap.

 

Go and buy a new telly, put the dead one in the shed, you never know what may turn up.

I think that for the cost of the mainboard and replacement, you can buy a brandnew 50" Panasonic, if you look for end of line displays.

 

I have a 60" LG Plasma from 2010 which was hit by lightning, and LG asked me 12000 Baht for the HDMI board.

 

That was also a 100.000 Baht tv at that time, but no hair on my head ( I have only few left) would think about spending 12.000 Baht on a tv of that age, because next year something else may break down.

A friend around the road has very poor power supply which resulted in damage to A/C, large LED TV, washing machine and a few smaller items.  He approached the local PEA and stated that due to their inadequate supply of power his personal equipment has been ruined.

 

PEA reimbursed him but only for 50% of the replacement value, apparently they do have an insurance of sort but only pay a maxm of 50%.  One would think it better if PEA just sort out the power supply or a continuous line of claimants will come forward. Perhaps the average Thai doesnt have as many electronic goodies as the average foreigner???

 

Onto the OP...it is very much a disposable society and technology is always on the march forward (Very debateable).  I had an expensive washing machine and dry combo. The PCB is kaput and a replacement board is about 8K.  New basic machine can be had for less money or a similar machine for about 14k.  Economics suggest that the old washer becomes a boat anchor.

 

I may even revert to a twin tub machine... not so many electronics to be fried!

Interesting. our Samsung inverter washer has gone phut for the second time this year. First time it was fixed under warranty, this time I think not (waiting for the man). I'll get wifey to ask the man if he can certify it was fried by bad power and see if PEA will pay.

Thanks for all replies!

I've been monitoring eBay and tried to post on Panasonic's online sites in case somebody with a compatible spare mainboard would turn up, but unfortunately nothing. So I suppose I'll have to go with a LED TV this time. Samsung has a 55-incher at Lazada that sells for just under 22,000, so that'll have to do. Current budget won't allow an OLED.

 

I was told about the possibility of getting reimbursed from the PEA by a friend, but it's valuable information for others who may find this thread later, so thanks for putting it out there, CMKiwi. The stumbling block was that you need to correctly state exactly when said power spike happened, or they won't accept responsibility. And I did not discover the problem for some time as it was raining (no use of washing machine) and I rarely have time to watch TV anymore. So that's that.
