Looking for schematic of Hitachi 43FDX01B TV- 18 pin transistor

I have a Hitachi 43FDX01B rear projection TV. it was in the middle of being repaired. no more repair guys. the tech removed two large (18 pin) transistors on a large heat sink. (large amplifiers?) i want to locate the parts and install them myself, but i don't have the parts and don't have a schematic.

how can i locate the parts?
their name/number?
any suggestions?
thanks,
Michael

    Thank you so much for your response.that's the information i needed.
    but i just checked, model # on my TV is the 53 (with "A") not 43.

    Model # 53FDX01BA
    i just wanted to make sure-
    is it still the same component number?
    STK392-110

    thanks again,
    Michael

The parts that are missing are likely to be the convergence ICs. These are STK392-110 and should be available online from any electonics parts supplier. Expect a cost of around $25 each.

Cant seem to get it to focus using the lines what to do now hitachi 43fdx0ib


The two stk-392-110 convergence chips this set uses will have to both be replaced. On EBAY you can buy a pair for less than 11 dollars plus shipping.

Repair involves two things: getting at them and being able to unsolder and then solder the new ones in. Chips have 18 pins and if you think this is a repair you could do yourself I am willing to assist you with it.

Let me know if you have questions as I am here to help.

Try adjusting the convergence. If it won't move see below- (or hitting Magic Focus for some Hitachi’s)

This sounds like convergence output IC problem. convergence board would have to be removed - remove and replace 2 STK IC's and check the surrounding resistors. Shops usually $200-$400 Be sure to vote/rate me if this helped Thanks!

Hitachi FDX Series 43FDX10B; some double/color problems,no remote


I am the right person for your problem--

If model number is 43fdx01b it uses two convergence chips--you are going to need to get your hands on a Hitachi remote if you do this repair.

If picture looks 3D, double image one or both of the two chips it uses for convergence is bad.

With the set unplugged and the back removed look on the far right side of the set---two versions of this set---one has a circuit board on the far right side about 5 inches wide and 12 inches deep--the chips will be on the large metal heat sink with fins on the far right side----look at the chips.

They are black in color and 2 1/2 inches wide and 1 1/2 inches tall with 18 pins each---They will most likely have the STK-392-120 NUMBER printed on each in white.

If you have this version the board is held in by 3 screws---you snap up a row of black plugs on the left side and several other plugs on that board have to be removed--if you do it---mark all the plugs so you get them back exactly where they came from.

Good news: total parts cost aside from a remote should be under 20 dollars---verify the number on the chips and I can tell you the best place to buy them.

There are about 12 resistors to the left of the heat sink that need to be looked at and tested--like checking a fuse.

Any resistor that is discolored in the middle or reads open needs to be replaced at the same time.

You might want to go to the house where you found the set and ask them for the remote--nothing to lose.

If you think you can solder etc and do this repair I will give you further specific instructions---this set is very easy to fix for this CONVERGENCE problem---

If you have more time than money--this is a very good TV--and this is about the only problem it ever has.

I am here to help---rate this solution if it helped you- I do this here for free.

I will follow thru with any help or questions you have even after you rate the solution.

Hitachi 53UWX10BA has double image


This set uses two STK--392-110 ( you can also replace them with STK-392-150 which is a upgrade for the original type convergence chips)----You can buy both on Ebay for less than 13 dollars plus shipping.

Both chips need to be replaced and any damaged resistors around them located and replaced also--most of the time the set just needs both chips replaced and then adjusted.

If you cannot do this repair yourself--look in your area--most shops TRY to charge 300-400 for this kind of repair----I do lots of them here--did two Hitachi2.gif sets with this problem yesterday for 200-250 total.

MAKE SURE WHOEVER you get to do this changes BOTH CHIPS--SOME techs will come out and just replace one--in a short time the set will have the same kind of trouble again---Now is the slow time of year for TV repair shops---shop around for someone who will do this repair IN YOUR HOME--almost any good tech can do it in about 1 hour---if they say it "has to go to the shop" keep looking.

The chips are black(2 1/2 inches wide and about 1 1/2 inches tall with 18 pins) and will have the STK number printed on them in white--they are located on either one large metal heat sink2.gif with fins or two smaller heatsinks that are side by side.

Hi,
Seems convergence out IC is fried in TV so it gives blue shadow.

Check out Convergence Out IC which you need to replace in TV, if you have enough experience of repair of big TV, necessary tools and know basic electronics.
