Question about Sanyo DP46849 46 in. HDTV

Open Question

I Replaced my Sanyo DP46849 T-conn, but...

I finally replaced the T-conn board because the TV was close to unusable. It slowly became darker and darker and then started to ghost on the right side. The Darkness is kind of gone, but the color and ghosting is still there. I really hope I didn't spend $50 on the wrong part. Any help is appreciated.

    I fixed it. Turns out it wasn't a T-con issue at all. Good thing I spent the $50 on the board. One of the flex tab cables is wonky.
    I emailed Sonny at tvrepairworld.com and he said to put rubber between the frame and the tab cable. This didn't work. I tried it about four different times. It didn't want to work.
    I finally got sick of it and busted out the Kapton tape I use for my soldering (thin sticky film tape useable at a wide range of temperatures), and taped it into the position it wanted to work in.
    The TV has been on and working flawlessly for the past 4 hours. Good enough for me.

SOURCE: sanyo dp46849 right side is darker

es it sounds like a Tcon but be careful ordering one because Sanyo had about 9 different versions of that model number all using different boards. You can get the correct one and free repair assistance from www.tvrepairworld.com

The problem is in the power supply! You must replace the capacitors next to Connection 2 (CN2 is the location). Replace C615 16 volts at 1000Mf,C621 16 volts at 1000Mf, C605 25 volts at 470Mf. C632 is fine, leave it, as is. The 605 capacitor (25 volts at 470mf). Looks good, tests good, replace anyway! Now with this complete, resolder all of the transformers (Large and small) pins you can find. Resolder inverter connections CN4 and CN5. Resolder any and all heat sinks (these hold transistors and mosfets). This will correct the dark shadows you see on TV. Thanks for asking, Matt of Martins TV.

Vertical half screen gets darker


There's a board in the middle of the set ( back taken off) near the bottom of the screen. It has 2 flat ribbon cables that go to the screen. It is under a metal heat sink. That's the board that's causing the problem. www.shopjimmy.com has the board for a very reasonable price. Takes about 15 minutes to change.

Computer chip


There is no "color chip" on Sanyo DP46849.

Perhaps it will be better if you explain what the problem is and let us try and diagnose the source of the problem.

Dp46849 Screen goes black after 10-15 minutes


This info was given to me by a HAM Radio friend that repairs TV's For a Living.
Disassemble TV, clean all boards from dust, unplug/replug all connectors,
most are really small, be careful, try TV again. Out Same Model TV started off the same, RIGHT bottom of screen/shadow when TV was on for awhile, since then has got worst, like 2 shadow boxes showed up, now upon startup, TV is screen is covered w/vertical lines, shut off the TV once or twice and works fine until next startup. If the above does not fix TV, look at the top of TV from Back Panel Off, Top-Center is a board called T-Con board, replace it. All the info for this board replacement is on the Bar-Code Laabel and Board itself, ie; T370HW02 VC CNTRL BD, 37T04-COG, FX-5546T03C22 (orC21)-964-0000NMP-00629-03 this board is Mgr By AU Optronics. GoTo For Parts/Pricing, they have 180 warranty on parts, aprox $45.00 for T-Con . http://www.shopjimmy.com/auo-55-46t03-c22-t-con-board.htm. He stated It IS Very Rare That The LCD Screen Itself Would Be The Problem. Right now I have Our Sanyo DP46849 apart
laying down on a bed, had to remove Base Pedestal to remove back cover,
There is a smaller cover, 2 screws u can remove to gain access to the turner board and power supply, there are 2 more boards hidden, before u remove back cover from front panel, untape wire leads from back of LCD Screen and unsnap the 2 torrid coils, black plastic things wires going through, these torrid/ferrit coils are mounted on a snap-in base, w/very small screwdriver they will unsnap from plastic base in 4 corners, if the base breaks from panel frame, just hot reglue back in place when are repairs are final. The 2 panels will seperate eaisly, if not you have some maore screws left to remove. Our TV was little dusty inside on the power supply board and alot of dust collected on some big transistors, 3 lead/legs, I'am hoping this caused the power problem @ start-up, going to clean all bard then reconnect all leads/cable, ect and retry, If no work will replace the T-Con board. Hope This Help's All

One side of the tv has a black shadow and then theres all kinds of lines and no picture sanyo Dp46849 1YEAR WAARRENTY HAS EXPIRED \r\nsince this a factory defect will sanyo replace or repair?


Hello
The video output sectioon of your tV is faulty. It has to be replaced as card basis. No repair is possible on it, as it is a machine pressed soldered board. If the set has still warranty, get it repaired bu the authorised service center for Sanyo. The board is a little costly one too. OK.

My sanyo dp46849 screen is discolored with red and black, any wisdom is appreciated


common issue with this model. if im correct not only is it red but it also has a ghosting affect this is caused by bad controller boards connected to the tv screen itself it is not any easy fix the only real option is to replace the whole panel which can cost between 200 to 1500.

Hello; I am John at J. D. Electronics, Poland Maine. This problem is caused by a defective LCD panel. This part is very expensive! Aprox $ 1000.00 from Sanyo and less than $400.00 from Encompass Parts Inc.
