Sony tv model kv-32xbr55 There is a 7 inches green horizontal (running from top to bottom) bar blocking the left side of the tv screen. Sometimes the screen goes dark but turning it off and on gets it back bright and good. I have had it since 1992 without any isues whatsoever Dee [email protected]

    Thanks for your concern Abrsvcs. If you will believe me, over 15yrs ago I used to be a tv tech. I have the basic tools but without a circuit diagram and with 15yrs in between the inside of the tv looks foreign to me now. Help further if you can. I have it open beside me.

Please DO NOT attempt to repalce the flyback as mentioned in the earlier posting. There are potentially dangerous voltages (33,000Volts) present there even with the TV unplugged. Your set has a problem with the horixontal circuit that can be as simple as a bad solder connection. I would recommend that you get a detailed repair estimate from a local repair shop BEFORE you attempt any repair. Please note that we can help to guide you through this process, but caution is required.

    Sorry about the delayed response. The Email notification system is having problems. I should have access to the service info on this model. I'll look it up tonight and update this with the likely parts/areas.

Check and change the line transformer. that transformer with a big cable running to your tube. that has a leakage in side it. after some time it is changing values.

    teh tv which has horizontal not fully opened. near the line transformer measure those eletrolitic capacitors, for leakages and change of values. the oscillation has changed. if you check from the scan coil, two wires are for verticle and are going to an ic on the card, and two are for horizontal and two wires are going to eletrolitic capacitor. plse check.

How do I fix a Sony TV that starts then screen goes blank

Check and replace damaged component/s at its horizontal scan output section circuit. Check the LOT (Line Output Transformer) too for damage. Replace the horizontal scan output transistor. Check the input voltage to LOT. If the voltage is absent check the feeder resistor; if any. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts.

This TV needs a service adjustment done. Looks like a vertical or horizontal IC is failing. I'd go ahead, and shut off until services adjustment is made. Have you unplugged for a few minutes and plugged back in? However, I'd have a service tech look at it.

DLP HL-R5067W

Your model has a maximum resolution of 720p. What you might want to do is make sure that both your cable/sat box and game stations are outputting at no more than 720 resolution. It's easy to assume that all HDTVs may accept a higher signal, and while they might, some of the scene changes or handshakes may make that operation cause the symptoms you describe.

Picture deterioration

Your whole problem my freind is dryed up capacitors. You should go, if you have the technical ability to replace these capacitors, to http://servicemanuals.net, download the schematic diagram, and start replacing the waveshaper capacitors in the vertical drive circuit.

Green screen with almost horizontal zigzag lines

Is good that you hit it and it reacts,very likely you have loose conections in different places but for the distorted picture you need to check the horizontal driver transformer and flyback after that is corrected you need to check the complete chassis for loose conections.Take your time.Good luck.
