You have a Sony that won't power on and the standby light blinks... Help and suggesti - Page 3

Sooo, I figure the D board which has now become a centerpiece on my diining room table is history, bust out the 15 watt iron, the desoldering braid, and the remnants of 8002 come right out, have already seated the new IC, I'll be laughing my po'o, head, off, if the other one comes out.Go figure............

Sears called this morning, the D board is no longer available, they have credited my credit card, so it's back to the desoldering again, about 9 pins to go on the 1605, what a pain, AND A CHALLENGE!!!!!!!!!!!! Why do the big guys, Sony, Panasonic, Samsung not support their products with after market replacement parts????????????????? Kind of makes you wonder......... Hopefully I haven't fried the motherboard.

Did you remove the D-Board for your soldering? Partially - I have remounted the tv in an a/v wall unit. Built a new mounting frame to fit the cabinet.

Did you use solder wick for desoldering? No - I tried but from past work, I had a good solder sucker and a good temp controlled soldering iron. I just resoldered the joint before sucking.

Any other comments on your repair? I had schematics from when I bought the tv. As far as experience, I used to integrate oem monitors kits into our product line so I have built prototypes and a lot of experience with chip removal. I used TSM for getting ICs (prompt, no problems) - bought 2 ICs have used 1. I initially thought I had blown the DVI interface card as I felt a spark when redoing my rf cabling to my cable box. I disconnected the board and the 6 blinks went away for about 2 days. It came back and I went searching. So far everything is going fine.

Then I solder the tip of the iron with a small bead of solder, place the solder sucker in position, apply the tip of the iron to the leg and release the solder sucker. In the case of the kv32hs510 board, the holes are only partially soldered through the board and make it easier to extract than thru the board plated holes which sometimes whick the solder all the way up the leg of the chip. The key is releaseing the solder sucker while the solder is liquid and not having it jerk away while sucking.
Hope this helps.

Of course, I'll know later this evening if it all works out right.

I am waiting for my six MCZ3001DB chips to arrive from eBay ($28 incl. shipping), and I plan to replace the 6501 and/or the 8002 on the D board. I plan to use 18-pin sockets. I have chosen to do the repair with the TV face down, which neatly exposes the D board (see picture). To get at 6501, I gently cut the gray plastic support with a knife. I'm ready to go for chip replacement, but I'm wondering if I should do one or the other chip first, or just do both. From what I've read here, sometimes a new 6501 made the TV work, and sometimes a new 8002 made it work. I'm thinking replacing both would be best, BUT I have only a little experience soldering, and I don't want to have my unskilled hands poking around with a hot iron any more than I have to. Thoughts?

A few questions. Did you inspect the board, after removal of the old ICs, for damage to the traces, etc. ? Did you make sure the orientation of the new ICs matched the old ones? Did you inspect your soldering for shorts from pin to pin, etc. ?

Good Luck

Will give it another go, check for oversoldering, etc. Regardless, Aloha nui to all you guys for the support and advice, if I can't fix it I will send it out. Sony has yet to return my phone call???? What a great support system, they should log on here and learn a thing or two................And I can now remove that D board in about 3 minutes, piece of cake, (just need the proper sized sledge hammer, I personally prefer a 12#), actually 3 to 5 minutes is all it takes to remove it, I can't imagine trying to work on it with it still in the TV.

I started by replacing the 8002 chip and fortunately that was the one that caused the problem. I spent $28 for 6 MCZ3001DB chips from eBay, and $23 at Radio Shack for a 25 watt soldering iron, solder (0.032", 60/40 rosin core as recommended), desoldering braid, two 18-pin sockets, a practice printed circuit board, two more sockets for practice, and an electronics air duster can. Desoldering was not as difficult as I had anticipated - that desoldering braid works great! I was glad I practiced first with the (inexpensive) circuit board and sockets. I soldered them in, desoldered them with the braid, then soldered them again to simulate what I'd need to do on the TV. It really helped me know how long to hold the iron at the joint, and how much solder to use. Thanks a million to RobertF for his soldering tips and to everyone for all the information about their experiences with these great Sony TV's.

Did you use 18 pin sockets? If so, make sure that the ICs are fully seated and installed in the proper orientation. And if you have extra MCZ3001D ICs you could swap those with the installed ICs in the event one of your new ICs is defective. (That's certainly a longshot but it's an easy check if you used sockets.)

You might also want to double-check all of the D-Board connectors to be certain everything is hooked up securely. You might even want to disconnect and reconnect every connector.

If none of that works you could still send your D-Board out for repair to a place like tristatemodule.com. Plan on about $150 + shipping costs in both directions. (Of course, you would be gambling that the problem is on the D-Board.)

It did make the "noise" when I went to turn it on, then nothing since.
