SHINDENGEN MCZ3001DB Replaces - MCZ3001DA & MCZ3001D & 670581001

My SONY KD-34XBR960 stopped turning on the other day, only giving me a status of 7 red flashes on the front panel. I looked it up and was pointed to these chips on a few pages. I figured it was worth the effort to save my beloved trinitron and now with a sore back from being hunched over this behemoth for a few hours I can proudly report that it worked.If you are going into this at a novice level, thats fine, you can almost certainly do this. Be here's my takeaway, and advice.YOU NEED A SAFE METHOD TO DISCHARGE THE CRT. look this up. You don't want to touch this thing if the tube is still charged. Watch a few videos, learn yourself a few things. If you don't have the patience for that then don't bother trying to fix the TV yourself. This whole process is going to test every bit of patience you've got. You'll need general soldering equipment, iron, solder, de-soldering pump, heat shrink tube, wire strippers.You'll want screw drivers, a light, a marker, and a camera to figure out pulling the board out. Mark your wires and take pictures before you start undoing things. There were about 30 ribbon cables in my TV and I ended up unplugging over half of them. I had to cut a few wires as well so you want heat tubing to make sure it's safe if you need to solder back severed wires.Dude. If you are reading this review because you want insight into those 3 black clips on the bottom of the KD-34XBR960 that hold the circuit board sliding platform to the bottom panel of the TV, I just said f*** it. I broke them off with a pair of pliers and now the platform slides in and out like this one manual I found said it's supposed to. There are still 2 screws on the bottom of the TV that work with the clips to hold them together so make sure you get those out too. If you get those clips and screws out of the way and then unplug the appropriate wires, you'll be able to take out the entire platform with all of those boards and ports on it. With only 2 more hard connected wires leading to the electron gun. I cut those. DOCUMENT EVERYTHING. GOOD LUCK 👍

I'm still in disbelief that this actually worked. My obese 300lb. 17 y/o Sony KV-40XBR800 wouldn't light up and displayed 6-7 LED blinks followed by an immediate shut down. Sometimes 6, sometimes 7. Too big to take out to the curb so I decided to tryta fix it. Google-ing the symptoms led me here to get these two MCZ3001DBs which came as a pair with sockets. Did a lot of research on how to do this repair - especially CRT discharge. Studied the websites listed in these reviews. Bought a lot of chit here for this project on AMZ, but the only stuff I used was a 0.025" de-soldering braid and a 65W Tilswall Solder Station, using the included solder. Meticulously de-soldered the original MCZ3001D chips on IC6501 & IC8002 (easy-peasy with the braid...solder sucker sucks, and not in a good way). I used the lowest temp necessary to prevent damage. Inserted the new chips into the sockets and re-soldered while wearing the dorky HFT magnifying visor. Plugged it in and it worked! Powered down, let stand a few minutes and repeated several times. Still worked and continues to work 6 months later! I was a hero in my wife's eyes for about 10 minutes, then she reminded me of things that I haven't gotten done yet. Hope it breaks again so I can reclaim that 10 minutes of glory : \

After Googling to find the cause (and fix) of the 7-blink error code on my kd36xs-955. I figured it was worth a $23 gamble to see if it would fix it. I wasn't against spending money on a new TV, I just didn't want the hassle of disposing this 255-lb behemoth and also having to find a new multimedia stand or wall mount that fits in a corner. The TV is working as well as it was before.Note: this is not an easy repair. I have a decent soldering station and the required tools. I had not de-soldered anything in about 20 years though. The entire repair took me a little over 4 hours, but I had to take several breaks because I was in many awkward positions and my back was killing me. I got a couple of leg cramps too (physically, I'm kind of a trainwreck). The work itself was probably 3 hours. It took me a really long time to get the board out into a position that I could work on it. The de-soldering was tedious, but I eventually got it and the re-soldering went surprisingly fast. I was truly surprised when the TV came back to life. If you want to try this, please take your time and take all appropriate safety precautions.

Just like so many others who reviewed this product, I have an old Sony HD CRT TV that stopped working. This was a shame, because the TV has a wonderful picture (much better than most flat panels -- especially when playing lower resolution source material (like old video games)). When I would try to turn the TV on, the LED would flash 6 or 7 times and the TV would then turn itself off. I saw Lee Devlin's fix on the internet. I consider myself pretty handy, but desoldering ICs and soldering in replacements seemed beyond my handiness level. Nevertheless, I took a stab at it. It was pretty challenging (if you're not mechanically inclined -- beware). After I replaced the parts, I really didn't have confidence that I'd fixed the TV. However, I turned it on and it was back in working condition (with beautiful picture -- perfect for NES - N64 era gaming (or just watching TV)). If your old Sony has stopped working, maybe you should search up Lee Devlin and try to determine if you think the set is worth fixing. I'm really glad I did.
