Replacement plasma TV semiconductors?

[Tibbs]

Got a Panasonic given to me, traced the problem to a shorted 2PG002 transistor and a questionable MA3DF30 diode. I've spent the day on and off looking for parts. Anywhere in the States to get these? I don't feel like waiting for a slow boat from Japan.

Yeah I'd like to know too. If you can work out what values to load into this

Maybe you can find a sub?

Yepper, already have the data sheets and know what the parts are. The problem is finding a vendor that ain't in China. I may have to resort to hitting the US semiconductor mfgs and see if I can match them up. Thanks for the help though. I used to repair TVs many moons ago. It was hard to troubleshoot them, easy to find parts. Now it's easy to troubleshoot, hard to find parts lol. I damn sure ain't gonna spend 80 or more bucks for a board. It'll go in the scrap pile first. I'm just not up on new TVs and thinking the parts may be a little more critical. I guess nobody knows how to troubleshoot at the board level anymore.

Few I would say. yeah I'd rather replace a $5 part than the whole board but sometimes the whole board works out faster and cheaper if there's a lot of blown parts and any doubt if you've got it all.

The only boards i've had heaps of success and cheap are some samsung ymains.
i have purchased some bits from china with success but it's risky.

Excuse me, but there are still many of us who are quite capable of troubleshooting to the board OR component level. Unfortunately, that skill is severely hampered by the fact that manufacturers no longer provide complete schematics/service manuals with the detail required for component level troubleshooting. They also will not provide their proprietary integrated circuits as parts. When modern boards are comprised of many LSI integrated circuits, often totaling over a thousand individual pins, and hundreds of discrete components, and service literature consists of glorified block diagrams, the amount of actual troubleshooting you can do on that board is pretty severely limited. You can quickly tie up far more time (= MONEY) than the new board would be worth.

The full part number for the transistor is 2PG0020000RP. There is one seller on ebay selling what look to be pulls. You can have them special ordered through partstore.com and possibly encompassparts.com. I can't find the diode but the one listed on Encompass is MA3DF40000LZ and may be suitable for what you need. This is also available through partstore.com and Encompass as a special order it would seem.

@Randek. Having also worked in Industrial Electronics for the last 40+ years, I've seen many techs who couldn't troubleshoot at component level simply because they never had the experience. It's more economical to swap boards. Let's face it. 4 years in tech school really teaches you nothing. The learning comes working in the field. Consider yourself one of those special people who can. Didn't mean to ruffle feathers in here. I'm just a tired old fart who still likes to tinker.

Thanks Rayrod and Tw2005. We'll have a look.

True but if your in the states you're ok but I found with the hits i got the sellers either did not ship outside USA or had rediculous min order values.

That hurts.

To anyone interested, with the help of Rayrod, I stumbled upon a bestbuy parts site. Prices are reasonable too. My particular parts are out of stock though.
