You have a Sony that won't power on and the standby light blinks... Help and suggesti - Page 59

post #1741 of 1759
Thanks ivtec! I take it that's copy&pasted from the aforementioned technician/thread.
post #1742 of 1759

I have a 2004 Sony KF60we610 that had the "5 blinking light" issue.  I replaced the thermal fuse, not an easy task as I had to remove the entire Optical Unit to get to the end.  They commented you didn't need to remove the fuse but there was no way to get the fuse end in the correct spot.  That did not solve the problem.  It took 50 times to get the TV to say on.

 

After more reading it looked like the G1 board was bad, however you can't get those for little $ or you must send in for repair. After many hours of reading, it looked as though the ic1601 was the problem, 17 Volts not supplied.  I ordered the 18 pin mcz3001db ($8.00).  After using ChipQuick, 30 W soldering iron and paste flux, I was able to loosen the part.  The location on the board makes it hard to cut leads so I just crushed it with pliers.  With patience, I was able to remove all the old solder and leads. I replaced the chip,plugged it back in and now it works great.  Note, there are 4 connections of the G1 board to the Main board.

Gotcha. Man they're really 'marketing' for this problem. wink.gif

Please I need advice on what's going on with the tv. Do you know if the D-board has to do with this issue?. Thanks in advance.

Please, help me, any advice will be greatly appreciated. Even the front input has the issue. Do you think it has to do with the input board or the processing image board?

Hi Floydage: today i opened a hole on the side about 12 inches square by cutting the plastic to gain access to the Mcz30001 chips,and i thought i had extra chips but i don't ,so i have to order them but Tristate is out of stock! do you know somewhere else with good reputation? also i noticed also the C6501 is a little bulging so that one has to be changed for sure
so it seems that the advice given when changing the chips so change the caps and the resistors and that's what I'm gonna do.

Wow ivtec, that's some serious serviceability access you've created! biggrin.gif That reminds of the ol' Quasar 'works in a drawer' TVs that were designed to be repaired because TVs broke all the time in that era (and hence the sell-out to Japan). Now I have drilled holes in the back of TV cabinets that didn't give me access to the HV transformer pots (why no access?! mad.gif ).

Anyhow, no I've never bought any of those chips but have seen posts with vendor links. Try 'Search This Thread' using that part number as the keyword. Might also do the same after backing up one step into the main CRT thread.

Sounds like good advice changing those other parts, especially since it was shown by a vendor. Maybe some of the other vendors have more info too.

Well i ordered 4 mcz3001 from amazon.com 44bucks,and i have a Sony kv36hs500 Chassis that i found on the scrap that some time ago someone damped a Sony tv on the side of the road since i could not carry the whole thing i just took out the chassis with all the boards,i guess it probably suffered the same symptoms,so tomorrow I'm gonna take out the 1200 uf cap and resistor .1 ohm 1/2 and test them if they are ok just swapped them.

here a few instructions

What's that guy doing on the side of the road over there? biggrin.gif
I saved the chassis from my '93 RCA 31" Home Theater TV as a degauss 'module' for my '93 GE 27" TV (similar Thomson chassis). The GE degauss circuit fried and so whenever I reorient its position I have to manually degauss it with the RCA chassis.

So did you find the resistor blown in combination with a bad cap? (i.e. do they blow in tandem?).

Since you're not having much luck here I'll say that if it were me I'd find another one on Craigslist. I see these and other similar 27" CRTs all the time for free or really cheap. 27" is the limit of my lifting ability and I purchased a small furniture dolly for about $10. Did this for an RCA 27" (HD AND built-in HD tuner) I got for free plus a Sony KV-20FS120, and the guy even carried them out to my van while I was getting the dolly out (big guy was in a hurry and dinner was about ready biggrin.gif ); I was actually going for the little Sony and told them I would go ahead and take the RCA, only to find out when I got home that the RCA was HD. Nice surprise!

Anyhow good luck and I didn't want to step on your new thread over yonder.

Happy Thanksgiving to all!

Nothing blew yet i don't want that , that's why i already ordered 4 MCZ3001 from Amazon.com , and 2 1200uf 250v caps and 2 .1ohm 1/2 resistors, i'm gonna replace the 2 MCZ23001 chips in conjunction with resistors and Capacitors, hoping this time it will last more then 13 months,


(What's that guy doing on the side of the road over there?}
well here in the Usa when some people don't know how to repair their tvs, and don't want to pay the city hall to pick them up for recycle have to pay ( 12bucks}, then they damp their tvs somewhere in the hidden corner, it's against the law,
post #1752 of 1759
ivtec - indeed, better safe than sorry. Was just trying to see if you observed any causal relationship between R and C (C causing R to blow).

Yeah I despise illegal dumping, we all pay for it via taxation not to mention ground water and visual pollution. Stupid that they can tote it somewhere to dump when all they had to do was take it to Best Buy (well free only up to 32"); may be other retailers too and I've heard about free electronic recycle businesses. I would be surprised if that city wouldn't have a free drop-off system like here (I wish we had the $12 pick-up service here for the bigger TVs). Hey at least you prevented one of the 'dirtier' sections of the TV from contaminating your ground water. smile.gif

I've seen that before. People leave a tv by the road and the vultures swoop in for parts. Usually they just create a big mess. I should leave my sony on the grass and watch it on our cctv system then make a video to post on the net. Lol

I have a KV32HS500.

 

Picture was fine before it disappeared.

 

Had the 6 blink, won't turn on problem.

I replaced the 2 IC and sockets.

 

TV turned on fine, but there was no red color.

 

I tried regular antenna, auxiliary, Video in from DVD. None had red color.

 

But, if I click on "Split Screen" the right screen has full color, the left one missing red.

If I go back to full screen from the right screen that has full color, the red is not there.

 

When I click on "Menu" The "Color" and "Hue" menus have red, but the underlying picture is still missing red.

 

I tried "Reset", holding down reset button on remote, and power on set. It reset but didn't fix the missing red.

 

Any ideas??

 

Thanks

Before what disappeared?

Are you saying it lost red after you replaced the two IC's? If so, Murphy's Law says something didn't get hooked back up right. I recall those IC's are for power supply/start-up/protection so I'm guessing it's somewhere else (i.e. a circuit board or cable you had to move/remove to gain access).

The PictureANDPicture stuff tells me it's the main input circuit; a secondary input circuit is used for the second P&P. Menu stuff is independent of the input circuit. The good news is that the TV is still generating red.

Check the module where the input connectors' cables end - specifically how the module connects to the chassis, its control&power supply wires, and output connections.

Yes, the red disappeared after replacing two ICs.

I just took it all apart again, lifted up the D board and carefully reassembled making sure all connections were tight.

Same problem.

I took a wood paint stick and prodded various connections and wires to see if something else was loose, but no.

I'm not sure what you mean by "the module where the input connectors' cables end - specifically how the module connects to the chassis".

Any ideas

Thanks for your help

There should be a circuit board, and most likely in a shielded box, where those cables go.

Other than that resolder and check the two IC work, especially making sure multiple pins didn't get solder blobbed together. Since you used sockets, check conductivity between each IC pin at top of the IC and the circuit board connection.

Hopefully nothing got static zapped.

Sadly I've had to dispose of my 34" Sony XBR800 CRT as I've got builders coming in to replace all my windows soon and I would have had to be shifting the TV around a lot, which is impossible for me on my own.

However, I removed all the boards from it first, so if anyone is interested in buying them, please have a look at my classfied listing for further details.
