Blue Yellow Wave

There is a blue and yellow wave across the top half of the screen and a sort of ghost below pictures on the screen. I have to drive this 43" TV to another town for repair and was wondering if you could help me either solve this problem or suggest what the approximate cost would be to repair. The TV is approx 4 years old.

I believe what you have is a convergence problem and it is usually caused by two Integrated Circuits going bad which also opens up one or two resistors associated with them. Replacing the Convergence Ic'S - (Ik04 & Ik05) and Resistor Rk62 a 1.8 Ohm .5w. Metal Film type should take care of the problem. As far as costs involved, I would guess about $350-$425 to get repaired. With it only being about 4 years old, it should have that many more years left of good use for you.

I have a Hitachi Projection TV (43FDX01B). It has a blue wave across the top to middle of the picture/screen. I suspec it may be some sort of bulb replacement. I do not have a user manual. Thank you

Its much more likely to be a convergence issue with the blue . Does writting appear sort of 3 D looking? The user manual I have for that model if you want to send a request to [email protected] I will email the user manual to you.

Hitachi TV 43FDX10B has yellow line with blue curve line above it

It sounds like your convergence ic's are messing up

They have a kit for this tv it is available through local parts distributors
If you can't find it locally just Google HITACHI CONVERGENCE KIT

If you are not good with de-soldering and soldering do not attempt this repair. Remember to replace all the resistors in the kit

If you are not sure about doing this repair you should have your local tv guy do it for you

Typically this is a convergence problem and can be repair relatively easy. Refer to this video to determine if you truly have a convergence problem. Also make sure you use your TV's original remote to make this adjustment.

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;
