Hi all forum members,
Recently Sony wega 29 inch CRT tv came for repairs in my workshop .Model no. XR29M83. Set was dead. I found Hout short. I removed it & checked all supply voltages which were OK. Later I replaced the Hout, switched tv on. It made big spark from FBT & become dead again! After rechecking I found 3.3 volt pin (no 19) short of UOC IC no. TDA12067H1/N1BOBOKO. I replaced both FBT & IC. But now set is still dead. All supply voltages are still OK. No H drive pulses from UOC IC. No st.by. indication of red LED neither starting indication of green LED.
My conclusion is, as IC is brought from open market it contains no software in it. Now the question is, is there any method to load the software or from where to get good new IC or is there any other solution? Anybody have experienced same problem? Please share your views & provide me some solution. Thanks,
P R Gore.
