HomeCan't adjust the red horizontally Convergenge went out suddenly about a week ago. I can adjust the blue horizontally and vertically. The red will only adjust vertically. However, the horizontal is way out of whack. Any ideas? Thanks

eek im having the same problem..the convergence just went off..a month after the warranty finished! grrr! can anyone please help! I found your files, thanks. Mike I have the red vertical problem and replace the two ic's but the same prob. Then I noticed that the writing on one of the resistors was smudged, maybe it was burnt off. Could one resistor cause the same problem as a bad ic? I will replace it. Also, could you foreward me a copy of the service manual so I can find the pico fuses just in case? Thanks I replaced the two STK392-110 with two STK392-150. Seemed to go fine. But when I plugged the board in and fired the TV back up, the speakers just made a popping noise and the blue light blinked. Then the board started smoking at around the R854 point. In an earlier post Eric mentioned replacing the six 1 watt resistors. Two questions. Could a bad solder point on one of IC804 or IC805 cause a resistor to burn out? Is there a standard ohm resistor I can buy at Radio Shack to replace the exisiting resistors? They all seem to have a different ohm rating and I'm a novice at this whole deal. I guess one more question. Could a fried resistor damage other components in the TV? I am having the exact same problem except I have a JVC HV-53Pro, can anyone help me with this model. Wave line at the top left corner, it's my yellow that won't adjust. Help me please. Reggie It looks like I just got this problem too. If someone have the DIY guide to fix the convergence, could someone please e-mail it to me. Thanks, Brad Carlson. This guide has been done for about 2 weeks. If the guide has worked for you please post some feedback for the others. Thanks. I have thin red wavy lines on my JVC TV. How can this be fixed. Thank you. Lorraine Trying to fix a TV for my recently departed friends widow; red convergance suddenly shifted aprox 1.5 inches to the left, and unable to compensate enough using convergance menu adjustments. My friend researched the problem & ordered a new DV board. Replaced DV board last night, zero difference in the problem. Purchased a manual today and discovered no troubleshooting info/tips, nor physical means to adjust centerline of red gun. Can service-level coarse convergance compensate for the problem, or is the TV dumpster ready? I believe a tech service call fee exceeds the value of the set. Thanks. i have 2 tv's a pioneer w/ no pc and a mitsubishi with a red that wont mov, i wanted to know1 what does a low voltage power supply look lke 2 can i cut the wires from the convergence board from the pioneer and connect it to the wires from the mitsubishi/?? and if i cant, how can i fix the red that wont move - i also will need a manual if u can help me out the model is a mitsubishi VS-4001rs |
