Question about Hitachi 43FDX20B 43" Rear Projection Television

1 Answer

Resisters questions I have the same tv model and same problem. I think I understand the IC replacement issue (I've found a 2-pack for $22 on-line...do I need to replace 2?) but I'm not sure about the resisters. You mentioned one would need the location numbers and to research the value of the burnt resisters. How do I locate these...where do I look....what do I do from here? Thanks!

Its best to replace both IC's. As far as the resistors, there are location #'s marked on the board where the resistors are mounted. If any look burnt, get the location numbers off the board, and your model # and email me @ [email protected] I will get you the resistor values.

What must I replace to fix tv that show horizontal line across the screen


I would say your TV has Frame or Field collapse (white line in the middle) firstly if its there for any length of time you will have a burn line across the tube's inside which will be there for evermore.
This fault is mostly down to an IC which deals with this part of a TV and will be different in each brand of TV also the set will have a fusible device like a resistor to isolate a defective area this would have blown. This IC would be mostly alone fixed to a heatsink near to a plug at least with four thick wires leading to a large coil mass around your tubes neck for identification. Though what you need is an understanding in TV repairs plus a service manual because that IC may have blown because of problems due to other related components and experience is key here to look and understand. Please be aware there are high voltages in a TV some stay charged up for a good while, if you do not think you will be able to do this be safe do not start! call an engineer it may be cheaper in the long run and safer.

Hi there, do you have the schematics for the Panasonic CT-27sf37b. This TV won't power up but making a high pitch sound near the thermistor area. Thanks.


Hi Richard,


First of all thank you for contacting Fixya.com regarding your TV problem.

You have mentioned that you can hear a high pitch near the thermistor area and the TV won't power up. I've saw also in another link that you already replaced the thermistor but the symptoms still persist. You stated that the thermister heats up, that is normal and not an issue in this kind of symptoms. You can power up the unit even without the thermistor in the board and check if the high pitch will gone or not. But I've suspected that the symptoms will remain the same because the pitch came from the chopper transformer.

I've encountered this kind of symptoms not only on panasonic CRT TV's but almost in all brands. And the major caused of fault is the faulty electrolytic capacitor in the Voltage regulator IC. Your unit used STRF6524 (mounted on the aluminum heat sink) as voltage regulator IC and it has an electrolytic capacitor on its circuitry. I would advice you to replaced it to resolve the issue. The largest electrolytic capacitor is not the suspect here (don't replaced it).

Also check for bad solder joints around the regulator IC. Cracked, cold, dried solder can produced that kind of symptoms. It is hard to spot, you must used magnifying glass and work in the brightest area or much better to re-solder the suspected bad solder joints.

I have various of Panasonic schematic diagram but most of them is a LCD and Plasma TV. I don't have this model no. but please check the chassis no. of your unit and I will try again to find it on my supplier to give it to you for free as much as possible because I've saw it HERE but I don't think the price is reasonable.

Please let me know if you need further assistance.

Again, thank you and have a nice day!

Kind Regards,

NEED TO ADJUST VERTICAL PICTURE


Replace capacitors CX2105 (35 volts 220 Mf), CX2110(35 volts 100Mf), C2104 (50 volts 1 Mf), resolder resistors RX2115, RX2116,R2118,R2119. You will need to also resolder the vertical IC. I think this IC location is IC 2200, its been sometime since I repaired this one.Do not short the pins together with excess solder. The values on the cap may not be exact. Please use the cap value that is removed (remove and replace one at a time). The locations will be correct! This will remove the horizontal lines or bars across the TV screen. You may as well replace capacitors in the horizontal deflection area. By now you have bad caps there. The locations and values are, CX3218 (160 volts 2.2Mf), CX3205 (16 volts at 100 Mf) CX3413 (50 volts 22 Mf) and CX3416 (25 volts 100Mf). Thanks for asking and show all hands of support.

I have white spots and black spots on right side of Mitsubishi WD-C657. I've done research online, and have heard its the dlp chip. Is that true, and if so, is it something that I can replace myself,...


This tv is it the DLP projection light engine block main board itself is the problems,not easily to go into the tv itself and replacing the IC chip itself.Must take out many mechanical parts to get u the Light engine block it self.U can replaced IC but somethime the IC chip it replaced,will not solved the problems,because the tv problems now the it is spreading and going on beyond the IC chip itself.If want to keep this tv very exspensive repair,i would reconmend hire a bound qualify tv tech replaced the whole Light projection block itself,but first call Mitsubishi for some kind of deal,they might help with the repair amount cost.

WS-55909 convergence problem turns now into F9A04 Fuse issue


I had this happen on my WS55909 about 2 years ago. I dont remember what the circuit id's for the fuses were, but out of 6 fuses on the middle board, the two in the middle were blown. I traced the circuit schematic and found that only the convergence IC could cause these fuses to blow. It sounds like you already put in a new convergence IC (the one with the big-*** heat-sink which probably also needs a fan) but you need to make sure all those fuses on that board are still good. After I replaced that IC, my TV still didn't work. I went and double checked for continuity of all the fuses on that board and one was blown (after checking all of them and replacing the IC). Replaced it and the TV has worked ever since. Total repair cost was 23 bucks. Professionals recommended that I would be better off just buying a LCD TV than fixing my rear projection TV, but I still dont think you can get one of those as big as 55" for only 23 bucks! ****. BTW, mitsubishi would probably tell you otherwise, but you don't have to use those "littlefuse" fuses. I soldered in a fuse-holder for a glass fuse of the same value (5amp 125v in my case) that can be purchased at radio shack. A fuse is a fuse. My TV never burst into flames.

SAMSUNG 61HL617 TV COME AND LATER ON IN SCREEN COMING LINE CROSSING BUT STILL LOOKING PICTURE


This is 1 of 2 problems. 1; Convergence(depending on the model of the TV, the convergence ic's will have cold solder joints) 2: vertical ic issues.

If they are different colored lines & the picture also bends, it's a convergence problem. Else suspect a vertical problem. In the case of vertical issues, most of the time it's a defective capacitor (or cold solder joints.).

If it's the 3-crt kind of big screen, it's possible for one of the tubes to be going bad.

It would be best to contact a pro to take a look on your TV and replace the defective components. This should not cost you too much.

Good luck!

My Mitsubishi ws-65809 will not power on and gives error code 22


Your symptom sounds like at least one damaged convergence IC.

On Mitsubishi's you can sometimes rework the solder connections on each of these IC’s, although, if the convergence does not fix itself from time to time, you most likely do not have a bad solder connection. You will have a faulty IC. Since you now have an error code of 22 (which indicates a short on one of the power supply lines) I recommend replacing them both at the same time because the chips legs can fall off due to the heat of the IC. If you have a good low wattage soldering iron ~ 45W (available at radio shack) you can perform the repair yourself, and this will most likely take care of the entire issue.


I like to remove the board that the IC’s are on so that I can unsolder the connections and clean then up using solder wick (this is also available from radio shack). Removing the board is not a real issue as the connectors are all labeled with an alpha number, so that you can connect them back real easy. There are three in the middle towards the front that I like to mark with a sharpie as they are the red green and blue convergence coil connections (they are all the same size in a row). Just mark them with slashes, like I, II, III, or something like that. If you mix them up it is not a big issue, you can test swapping them around until the picture lines up.

Please be sure to remove the entire white heat sink compound on the heat sink and apply an even coating over the back of the new IC’s. You should also bolt them down before you solder them in so that you have them at the correct height.

There are two very large IC’s that control the convergence in a big screen set. They are secured to a very large aluminum heat sink. I think that the IC numbers will be IC8001, 80002.


The IC’s are large and black, you cannot miss them. They will usually have an STKXXX-XXX number on them.

This repair from a good technician will normally run from $250.00 - $300.00, and sometimes more depending on your area.

There are several schools of thought on the replacement of parts and I firmly believe that you get what you pay for, so don’t buy the cheapest IC’s that you can find. One company I worked for tried this and it only caused more work for the technicians, as we had to replace them with the more expensive ones in the end. I would think that you should be able to find these for around $60.00 each. If you can find the exact Hitachi part, or Sanyo, even though the numbers on the front are the same, and they look exactly like the $10.00 ones, they are better and more reliable.

I usually order my parts from Andrews Electronics in
California, they will have the OEM components that you will need.
Their site is http://www.andrewselectronics.com/welcome.aspx
And their phone number is a 24-Hour Order Desk: (800) 274-4666
I recommend the phone order so you can talk to the person about the different types of IC’s that are available.

You can also try http://www.tvrepairkits.com/ , I have not tried them yet, but they do carry OEM or better parts.

I hope this information allows you to resolve this issue.

R-22 vs R-134A


not a good idea to swap gas coz need to change tx valve and flush system and use polyester oil,cost a lot. ur best options is to repair, pretty sure it can be soldered

I have a Carrier 4 ton unit model number 661CJ048-A which is charged with R-22 capacity is 9,25lbs. It has developed a leak at the evaporator coil. It has rust on the coils which from what I understand...


First your system is 22 and 134A is a auto AC refrigerant. I have never seen it used in residential ac. I have been in AC business for 45 years. The new refrigerant is 410A or Puron. But you can not use it. Your outside unit is set up for 22. Mix 134A with the oil used in a 22 system is not done. You need to get the correct coil for your system. They are going to make 22 for years. They now have a Drop in for 22 called NU22. I know times are tough but you may have to get a Service Tech anyway.

Mitsubishi 1080 hd ws-65809 wont power up


This issue is almost always caused by a faulty Convergence IC inside your TV. These chips heat up and can become damaged over time. The most common cause I have seen for the picture distortion is the heat of the Convergence IC weakening the solder connection to the TV circuit board. If you look on various messages board you will see people rigging wooden dowels and other items to apply pressure to the chips in order to correct their picture issue. This works because when the solder joint is weakened the chip becomes loose and vibrations or pressure will cause it to work or not work correctly. Aside from all that information the correct fix is to have the IC chips replaces on your TV.

The solutions for this issue are as follows:

1. located a tv repair shop that will replace the parts for you. I had the same issue with my 65" Tv and the quote was $350 for the labor and parts.


2. You can ordered the IC replacements yourself online by going to google and looking up a reseller of the STK392-110 Convergence IC that is inside your model TV. You will need 2 of them and they cost around $6 each. If you have the soldering skills to remove the old chips and install the new ones this is by far the most cost effective route. It is a fairly simple process and guides can be found online.
