Question about Hitachi 43UWX10B 43" Rear Projection Television
I have replaced the common problem and the set still continues to have the wavy lines that look like 3d without the glasses. I had recently moved to another state and the TV was on a truck and after getting it here it worked fine again like before then back to the wavy lines. I have read that there where some bad solder joints or bad caps in certain spots on this set. Can someone give me a little more detail on the components they have replaced to fix this common problem. After trobleshooting and viewing over schematic i still feel it may need the PIP module but thats 400.00 and i would hate to replace it if all i have to do is replace some caps somewhere.
I dubt very much that the PIP module is causing a convergence problem. if you do think there is a PIP problem though, there is a repair kit available at mcmelectronics.com. Do a search for Hitachi PIP kit. It cost I think about 8 or 9 bucks. I would say you should take some voltage measurements and trace out the b+ to the source as thats where Im thinking your problem lies. In these sets I have found numerous problems relating to convergence, and most were found to be bad solder connections at the b+ supplys such as resistors caps and or jumpers in the board. Also double check your work, when you replace the IC's. I have seen a plug have way into the socket cause all sorts of intermittant problems also. Good Luck PS Please do not forget to rate this thread.
