Sanyo DS35590 35" CRT Television

I'm quite sure that the following parts maybe the cause,,namely:horizontal OT transistor,avalance diode,or vertical output IC....Dods

This tv problems,have 2 possibilities problems.1 the CRT(Tv tube) itself is dead.This u can hear the CRT Video board connection buzzing noises at the CRT-(Tv tube) head.The CRT is dead,also have a little high volt sparks flashing on the video board components too.2 is the FBT-the Flyback Tranformer is dead.This is a highvoltage transformer,a big black block of plastic with a red wire with a cap hook to the CRT(Tv tube).This will make buzzing sound at the base of the FBT.If it is the FBT-it is repairable,if u still can find the FBT part for ur tv model.This part the FBT is a critical part for the analog tv to work.Require tools and also know basic soldering too a must.

If your tv is a crt type. Could be shorted horizontal output transistor or flyback. If the flyback is shorted you gonna need to replaced also its HOT and check for other component.

I have two RCA HD52W59 TV's. I have had one for 3 years and one 4 years. The one I have had for 4 years is giving me the problem. Last week the tv turned off while watching it. It wouldnt come right back on. 10 minutes later we tried and it worked fine. the other night the kids were watching and it turned off and smelled like something burning. I tried turning it right back on and got no power at all. I tried to turn it on two days later and it made a buzzing noise and the green light went out. Never did get a picture, no powering up on the screen. Any ideas? Don't want to spend alot of money. Really loved the TV hope it isnt junk now. Better yet I hope the same thing doesnt happen to the other one I have.

This is what is known as frame collapse - which means there is no vertical deflection applied to the tube.

Please do not continue to watch the set in this condition as it may burn a horizontal line in the middle of the screen.

The most likely cause is either bad solder connections to or failure of the frame vertical output IC.

Please rate the assistance I have given - I hope it is useful. If you call a serviceman and tell him its frame collapse as this type of repair is not for amateurs - voltages in television receivers can kill.

Is this an LCD flat Panel Television?

That set is probably not ready for the dump yet. The buzzing sound could be the power supply going into shutdown because of a shorted secondary supply, usually a shorted horizontal output. A good tech should be able to fix that at a reasonable price.

Probably you had a horizontal output transistor short which in turn may have blown a fuse. When the horizontal output transistor shorts, probably the high voltage transformer (flyback) has also gone bad. Since the set is so old, you could replace it about as cheap as you could have it repaired. Stargazer

the horizontal output is shorted ,has to be replaced BUT solder all connections for three inches around the this horizontal and solder them well or the output will blow again,there is especially a small coil in the drive line to the base that causes most of the problem

This set is very popular for the capacitors to dry upa and go bad in the main SMPS as well as the switching power supply. If you have no know how on how to test capacitors or solid state electronics please take the set into a repair shop for an estimate
