Question about Sony KP-51HW40 51" Rear Projection Television

1 Answer

Hitachi 43fdx11b green wave on top left/center of screen

First the blue didn't move, so I replaced both ic's and 6 resistors. I had a great picture for about 10 minutes, then the green dropped on the top left and top center creating a wave that won't converge. I've rechecked all my solder connections and they seem fine. What's happening?!?! (other than it's driving me to drink! lol)

    What were your STK Numbers and did you go back with same #s.

Check your soldering.

Check the resistors - make sure none are shorted.

Make sure you did not buy fake STK chips...

You will need to replace your two convergence I.C.s.They are two large IC mounted on a large aluminum heat sink.Replace both,look for any burned resistors near them,replace those if needed,and readjust your convergence. Good Luck

Let me know if you need any further help

Hitachi 43fdx11b green wave on top left and center


Its likely that you did not find all the resistors that were damaged when the original failure occurred. Now you must re-replace the ICs and locate the other damaged resistors. Check all, including those you just replaced. Use a good ohm meter and be certain that all the resistors are gold band tolerant(5%) and of the exact resistance value and wattage.

Blue wave across screen


Just click below for convergence repair kit;

http://servicemanuals.vstore.ca/

Double images and colors are blurry .Blue,red and yellow wave coming up from the bottom of the screen on the lower left symptom is for busted convergence IC,you must replaced this IC in order that will works better again.STK 392-xxx ICs and it's associated resistor,this resistor automatically change value,can caused truoble even though you change the ICs.If you bring this to a service center they cost you $600 to $700,but if you buy the repair kit you can save more,don't wory it is very easy because there is intallation guide including in the repair kit. Feel free to ask whatever the result... click the link for sample picture guide step by step installation;

Hope this may help;

Top left corner double picture red and green


you have a failed IC resistor usually you can physically see the bad one because it burns out leaving you to guess what the value was. Hitachi offers a convergence fix kit which has 2 IC's and all approiate resistors.

I would change both ICs STK392-110 and also the 3.3ohm 1 watt resistors and the 1.8 ohm 1 watt you would need 2 of each resistor. Then your convergence would be new again. You can get replacement ICs and resistors at the following link with free shipping and free instalation instructions with pictures.

Double Vision ...w/waves on top/bottom too much green.


1024x768 Normal 0 Convergence


When A REAR PROJECTION TV has coloured outlines or a 3D image the Convergence Circuits most likely need attention.

Replacing the output amplifiers (located within the Convergence IC's) allows the pictures to line up correctly, and no more color outlines.

This is the most common fault in all makes of rear projection TVs.

Some models of TV require major disassembly and considerable shop/manufacturer's support to repair because of their design that causes other power supply or vertical deflection problems. The poorly designed products require a "bench" repair that can typically cost from $350 t0 $700.

Some TVs are designed for on-site repair and have more reliable circuit design that does not usually cause damage to other parts of the TV when convergence chips fail. The ones that usually allow reliable on-site repair are JVC, Samsung and Hitachi.

It is normal to have some resistors in the circuit burn up or increase in value from the heat (from 2.2 ohms to 5 or 10 ohms). These resistors must be replaced with the right value or the chip may fail again.

This is not a simple repair like changing batteries or a fuse. Reading through the other posts shows many that try and end up with bigger problems.

Your JVC uses STK 392-110 IC's. Misinformed people replace the IC's with other "new and improved" IC's, like STK 392-150. These are devices with different characteristics and require different value resistors in the circuit. Replacing with the STK 392-150 will cause overheating of the resistors and a damaged IC.

If you are in Calgary, I can help. If not, get someone that has experience working on your JVC. My website is below with some costs and explanation.

Hitachi 43FDX11B television Ghosting


I had the same problem on my Hitachi rear projection TV 53FDX20B made in Mexico. The blue convergence problem. Blue focus had shifted and appeared like a blue ghost image. I followed the step by step intructions from the fixya site. First Replaced the two STK 392-110 ICs and turned on the tv. No change. Then I went looking for the bad resistor. There was one resistor RK50 (2.7 ohm, 1Watt capacity) which is attached not right close to the printed circuit board surface but was well raised up from the board. The bands on the resistor were a little discolored. I replaced that one and turned on the tv. The convergence problem was solved. Thanks for the step by step instrucitons on your site.
