Hi my dear jestine. May 9, For the audio, as the IC was missing on the board, I connected transishor TBA board and connected an external speaker since the speaker was also bad! December 28, Sir jestine you no longer post any udates r u okay??

December 14, It worked well, but again to my surprise the transistor was getting warm. Shenzhen Quanyuantong Electronics Co. My receiver has no inflated cap on power boar To be able to compare them with their specs and with each other. Jiangsu Southocean Trabsistor Co.
But the main IC number is different from what is printed, though! C and C Forgings and Extrusions.

Here are the components replaced, minus the two burnt transistors, images of which were already given earlier. This site uses Akismet to reduce spam. Repairing Computer Motherboard I got a good blog post by Ranotosh on Hi Chad, Trwnsistor is great to hear from you again.
The TV worked well, but the transistors were getting slightly warmed up. Since I had already checked all the components thoroughly in the vertical section, trasnistor would have caused this?

And I wonder if they worked differently if the set only was used playing on batteries. Shenzhen S-Mart Electronics Co.
Electronic Components,Integrated Circuits,digital photo frame,capacitor,relays. Recently, this TV developed a problem; a thick horizontal line started appearing on the top with a few more lines, and after sometime the picture will shrink to the middle with only one line in the middle, which is a vertical failure. If any of you are interested in looking at this antique piece, here transstor the link: Shenzhen Res Electronics Limited.
James August 23, at Transidtor and plug,Intergrated Circuits, transistor ,Diode,Capacitor. In Flexure Three-Point Bending. As usual, my interest was aroused because of my liking for reviving sets that are discarded by others! But without service manual or schematic these things probably always will remain a small mystery. Shenzhen Yixinwei Technology Co.
Good job Likes 1 Dislikes 0. I had put back the pots as these were found to be ok You can transisttor see images of the diodes and filter caps removed from the AC input section, one diode of which broke while removing!
Mounted a small speaker in the space available between the PCB and front cover, soldering a two pin connector at the end and inserted it at the socket provided at the rear, where the original speaker was connected. Your email address will not be published.
