content: Hi all, I have a Mastech MS8229 Multimeter. I need to replace the small board that the leads plug into. I'll call it a daughter board?Is there anywhere I can obtain one. Do they have a customer service for example.Any and all advice welcome. Cheers, Tom.Location UK

content: Can you please update here, if your inquiry was successful?I tried contacting them in multiple countries across the world for a VFD replacement of an MS8050 and either the emails returned or never got answered.Maybe one day I can repair that unit.

content: Thanks for the info, I found a service center in Taiwan I think and left a message. I don't hold no hope on that one.I will try the POWER PROBE GROUP suggested, I know I'm asking a bit of a tall order.I'm just trying to learn schematics and motherboard repair from the various YouTube videos out there.My mate bought me this meter a few days back an I really liked the feel of it.Probably time to move on anyway as any minute now I've got an AstroAI TMRS 6000 arriving at my door.I can't get me head around the various brands business. I take it a no named factory makes it and sells it to be branded by whoever?

content: After many years Mastech replied to my email from a few days ago and asked for further details about serial number and fault.In my past tries of communication with them, this was always the end. THey never came back and I feared that my unit was kind of black listed or stolen?But they came back to me! They offer the replacement VFD for 80€ which is not too bad. But I have to arrange pickup at the Chinese factory and I have no idea of how to do that.From what I know from PCBWay this adds another minimum of 75€ of DHL shipping costs plus customs fees and taxes. In the end it'll be around 160 to 180€They also offer me a trade in for any new device at a lower cost. But I fear the costs of returning the defective unit and they actually do not sell anything I need or don't already have.And I also could program an OLED to emulate the VFD like it has been done multiple times for other units.Years ago I would have been happy to pay the replacement price, but since then I collected multiple HP 5.5 digit units, a few Philips and an R&S unit that also features all the real-time and true-rms measurement. I even own a 8075 transfer standard.Probably I just put the unit up on eBay again with a true and honest failure report. With a bit of luck I find the original packaging, test leads and manual together with the calibration certificate it came with.What would you do?

content: repairing your unit is the most cost effectiveyou loose time and money if say : you try the oled route time = moneyfor an exchange : is the suggested one is the same on specs or better ?i know shipping prices can or are expensive, but sometimes if you really really love your equipment ... ?

content: Again... I got the unit for little money as dead from eBay in 2015.I tried contacting Mastech a few times since then and first I never got a reply, one time they asked for serial number and fault but after providing the information they never came back.So I never had a chance to get a feeling of connection to the unit.They offered trade in for a different thing. But They do not sell anything that I need. They did not offer an exchange. However, they still offer the same instrument and it still has the same specs.They where good at times of 2015 but today I own an R&S HMC8012, two HP 3478A, some Philips PM2525 plus their extension case with all the high frequency, high current and high voltage adapters.So, do I need the Mastech unit? No.Do I want to trash a fully working unit that only misses a display? No.Would it make a nice rainy day project to create an OLED replacement? Sure!But I saw some units on eBay being sold as defective and they all went for a few bucks. So concentrating on all the other open projects and just selling the unit to someone with a dead mainboard but a good VFD is an option.
