I got the first set of STK392-110's from the vendor "coverlink" on Ebay. I'm not going to contact them with complaints because I cannot be 100% sure that I didn't cause the problem I was having. When I first installed these IC's I only changed the one on the red convergence side (IC804) and the corresponding 1.5 ohm resistor for red horizontal (the channel that was non responsive).
Since the blue and green were still working perfectly, I figured I might be able to get away with less work by changing just one IC. It was probably a newbie mistake and very likely could have caused damage to the new IC.
Anyway, the new STK392-110 had continued to blow the 1.5 ohm resistor on the red horizontal channel, so my next step was to change the other IC. After changing that IC, I still replicated the same results and became frustrated.
Since finding the used STK392-150's and changing both IC's and the resistor all at once resulted in success, I'd say it's fairly likely that I damaged the STK392-110's. However, it could have easily been DOA chips as well, since these chips from Ebay were only $7.68 after shipping and were sent from China. I should mention to everyone here that most of the Chinese vendors on Ebay have taken to misleading titles in their ads for these chips and listing them all as SANYO chips.
Thanks again for all the help this thread has provided.
My JVC D-ILA X3 showed the LED-code red - orange (permanently flashing) - red.
It was difficult to find solid information about this problem. A lamp defect code acc. to manual is red - orange (but only 3 times flashing) - red.
Meanwhile I've got my X3 fixed and I would like to share the...
Not sure if this is the correct place to post. Have a JVC HD-61FN97 Using it for off the air local HD channels and the thing started locking up with a green snow screen. Yellow/Red/White inputs still work. Anyone know of problems with this set? What board do I need to start looking for?
Hi everyone, I bought a JVC LCD TV a couple of years ago out of our local Harvey Norman Electronics Store. It was a really good TV which had clear picture and a good sized screen that we even recommended my brother-in-law to buy one.
However, just over our 12 month ownership of the tv, and of...
