Question about JVC AV-48WP30 48" Rear Projection Television

1 Answer

So.. Would the original or replacement IC be more likely to go bad again?

The replacement part is the exact part no. as the original (looks identical) so that being said would it make more sense that the original finally went bad or that the replacement went bad? Does anyone have a schematic for this unit that could tell me or send me?

Thanks again,
Tony

    Thanks for the info.. It dawned on me from my old elecronic tech days that I could isolate the bad IC by running the unit and checking to see which one was overheating or not heating up at all. It was right on with your information. IC-804 went to over 100 degrees within 60 seconds of turning on the set (and RED is the color that is off). IC-805 was only luke warm in the same time frame.



    Thanks,

    Tony

All the ics look identical even right down to the STK numbers. However if you didnt get the part from a authorizes Samsung vendor, chances are you got one of the cheaper made ICs. I will search for a service manual for your model. The other site I work as a tech on may have your service manual. I will check and post a link if they do.

    The other site has the two part service manual and schematics manual for your model. I looked it up. IC-804 controls the red convergence STK392-110 . If you want the service manual and schematics manual for your set let me know and i will post a link for you. Its two parts and cost 24.99 and they will email it to you.

I thought i might need a lamp for my mitsubishi tv--model VS 60607 when my tv is fuzzy when turned on.should i simply replace the lamp or is there something else i should try? thank you!


This TV is a rear projection television and does not have a lamp. It has three CRT color guns (Red, Blue, and Green). You have a convergence issue (the red, blue and green color guns aren't aligned properly) and it doesn't sound like a very big one. You should be able to adjust this through the CONVERGENCE Menu in ADVANCED SETTINGS.
More details can be found in your manual, here. The model number isn't exactly the same but I'm sure the process is identical or really close. The other option would be a bad IC (integrated circuit) for the convergence control. This is unlikely unless your picture looks something like this: captainhawk1_15.jpg

My gold Mickey mouse Lorus watch was opened a part damaged by the person replacing the battery. This is not a digital watch, but has nthe mouse with hands and a second wheel at bottom.


You are probably going to have to look for an identical watch for parts.You might try this site:
http://www.esslinger.com/watchparts.aspx?gclid=COCr3t2F9KUCFcIKKgodgiARnA which is parts for watches. I'd have a look on ebay as well for a watch that is not working. Of course it does depend on the part you are looking for. I am also wondering if the inner parts for another Lorus mickey moue watch might fit, but maybe you don;t wish to change it out from the original.

I need to put a new IC for my yamaha PSR- 150 however as i came to know that the parts for this model is not available .Can you plz suggest me where will i get ?


Try googling " cross reference for " insert number on I.C." integrated circuit." Various manufacturers have identical replacements but with different labeling on them. Make sure you compare the functions of the pinouts to the original and mount it the same way. Also try contacting WDGreenhill.com. They have a lot of hard to obtain parts. Try checking their site.

What is the best IC replacement for original IC part# STK393-110?


Sayo makes the best IC's, don't just settle for the cheap ones. I have see this ic for as low as $5.00 on the internet.

I would also advise that the convergence IC’s be OEM or better, just because they are cheap does not mean that they are a good deal. I have seen the cheap IC’s fail after a short time, even though they look exactly like the OEM IC’s. I think that the bottom line is that you will get what you pay for when it comes to the parts.

You can try http://www.tvrepairkits.com/ they do carry OEM or better parts.

I hope this information allows you to resolve this issue.
If you need further assistance please comment to this post and I will try to help you further.

Your symptom sounds like a damaged convergence IC.

There are two and large IC’s that control the convergence in a big screen set. They are secured to a very large aluminum heat sink. They will have a part number stamped on them that will start with an STKXXX-XXX, like STK392-110, and they are located on the signal board (on the left as you look into the back of the set).

Along with the convergence IC’s there will also be some associated components that will need to be replaced as well. There are some resistors that are part of the convergence circuit that will be open and need to be replaced. Most likely these will appear charred in the center. If you have an Ohm Meter or a DVM, check all the resistors that are close to the IC’s and you should be looking for either ones that have opened or have changed values.
There are also two resistors on the front of the board located in the middle that are fusible link resistors, these should be checked for opens and replaced if they are found so.

I would suggest that you contact a service center in your area for a complete diagnosis and repair, as this type of repair can get a little tricky. But if you want to repair the set yourself, just remember to be careful. The capacitors and CRT’s can hold a charge and may shock you.


If one of the convergence IC’s are found to be bad, I would replace them both, if one has gone bad the other may go soon. 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.

I would also advise that the convergence IC’s be OEM or better, just because they are cheap does not mean that they are a good deal. I have seen the cheap IC’s fail after a short time, even though they look exactly like the OEM IC’s. I think that the bottom line is that you will get what you pay for when it comes to the parts.

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.

Compare your rgb voltages and your cathode voltages(green, red, blue) and also access your service mode settings. It might not be the STK-392-150 that is defective.

PT-47WX53 blue convergence PROBLEM


Sounds like you have a blue foldover in the convergence. Since tv has been worked on it could be bad ic, maybe not original, generic. I would say if you can open set and look in, look for the blue it should be marked. look for a loose connection. If you can have someone to gently tap around that blue amp and see if it moves are go away, it might be a simple loose connection and needs soldering. If not then my have to change ic again. Becareful cause set would need to be on to really check. Hope this helps.
