Question about Sony KV-27XBR45 27" TV
My Sony kv32v15, suddenly shut down. When i tried to power it up again, it gives me picture for a few seconds then changes to a red screen with fine horizantal lines then shuts off. any help about what to change or where to look for thgis problem will be appreciated, thank you!!!
I would suggest to measure the 200 volt B+ at the CRT socket. If that voltage is found to be low, disconnect the socket from the CRT and measure again. If the voltage reading returns to normal you may have a defective CTR.
Also check for open or defective diode on flyback transformer for the 200 vdc source.
I would also suggest to take all the necessary precautions since you are working in a very high voltage area.
