Yes, that all-important visual inspection...

I have a TBS 1072B oscilloscope and after 3 minutes it turns off by itself. The capacitors are fine. That could be. Thanks

Do you know the manufacturer's model number for the panel, not Tektronix's part number? Mine blew out and it needs to be replaced. At first I thought it was just the backlight, but it's the entire display unit. Thanks.

Sorry for late reply. I just got my hand on one of these scope. For the color display option. It was the Kyocera kcs057qv1aj. For the monochrome version it's NAN YA ltbhbtd84h10ck. These displays are really expensive. I'm currently working on the FPGA-based replacement display converter module.

電気エンジニアですが、、コンデンサ部品を交換して動くというのは・・・設計ミスのようでなりません 部品交換して動く前に、なぜ動かなくなったかの原因が先にあるはずです。 「入力に過電圧/過電流を加えてしまって、ICが故障した」←この原因でICとコンデンサ、抵抗部品を交換して動いたというなら、納得いきますが、普通に使用していて、故障したなんて信じられません。 ましてやコンデンサを交換するだけで動くなんて、今まで経験したことが無い

信じられないのは、あなたの経験年数が少ないからだけです。The only reason you can't be trusted is because you don't have many years of experience.

@@tv9s2007 電解コンデンサが消耗品であること。コンデンサがショートモードで壊れることはわかりますが、稀な事例すぎます。 リプル電流など、電解コンデンサの故障率の設計もちゃんと出来ていない。設計ミスです。 そもそも質の悪い部品を使っていたのか、原因は別にあると思います。

​@@phantom4drone77Those caps in that PSU are notoriously know as one of the bad quality cap brands. IDK, I quote this from someone over EEVblog that also had to recap the PSU board.
