Problem with the Integrated Circuit (IC) of Television?

Question

I have an old Television which crashed. The repair guy told me that IC had failed. And I could not find a new IC of that type - because of very old TV. Ok, I don't live in U.S, U.K or Europe, so if TV crashes I can buy a new one. The place in which I live - TV are costly so I was adjusting with an old TV. But it crashed. So how to find it's IC?

And how to anaylse and read the numbers on IC?

Answer 1

Not every IC within the TV will be commercially available. ASIC (Application Specific Intergrated Circuits) are custom IC's supplied only to the manufacturer. You will not find these available through your typical electronics parts supplier. ASIC's may be available through the manufacturer as a replacment part and will be the only source for these custom IC's. In order to Identify the correct component ID you will need a schematic and parts list which can cost $25 to $50 (Sam's Photofax or a service manual ) The chip may or maynot have a number printed on it and the component ID on the PCB is not enough without the BOM or parts list to cross reference to a part numer.



One major problem you may find is that some manufacturers will only sell repair parts to authorized repair shops and will refuse to sell parts to the general public. This is a means of supporting their authorized dealers by limiting competition. I had this happen to me when GE refused to sell me a $5 component to fix a TV I owned. I ended up having to buy another TV. GE would not sell me the component as I was not an authorized service dealer.





The expense in getting information(schematics and parts lists) and repair parts is a major reason why electronics have become disposable.

Answer 2

Hi what the repair man is telling you is it matters not where you live it is no longer available as a spare part. which is a common thing these chips are made to order and a specific amount are made and when they have sold out there is no more so the products are only fit for the dustbin.

so just live with it, it is not a repairable television.

also i will mention a lot of the numbers printed on the chips are what is known as house number which bear no resemblance to what type the chip is.

Answer 3

Write down every printing word on top of IC line by line over here, then someone might be able to trace it for you. Some words printed on IC is useless,like the DATE Code.

Old IC can be taken out from other old same brand TV for serviceable parts if it was still good.

Answer 4

First you need to find out which IC is bad, and there a a lot of them in a TV. How are you going to do that?
