My mom has a RCA HD61W66 and the picture was showing red, blue and green "lines and shadows" as if the picture was warped. It has now stopped showing a picture at all but the power is working....


The flyback transformer has solder cracks around the pins and most likely blown the FL231 Micro fuse to the right of the flyback.I would inspect the flybacks solder. The FL231 and the CL230 and DL231 should also be replaced ( near the flyback) You can get the ITC222 Convergence option missing repair kit from www.tvrepairworld.com under the RCA repair kits. The kit contains the parts and the CD with repair instructions

Colored lines on top portion of screen with blurry colored picture


Hi:
This is due to a faulty convergence power supply or voltage supply to the convergence board, first thing to check is the deflection board this the board to the right of the unit look at if from the back.
Check all connection on the flyback and resolder is any cold solder joints are found. Also there are tree micro fuses the may of blown if there are any bad connection around the flyback.

Picture is 3D like with green, red, and bules lines at the top of the screen. It is also cuvred on the top, and bootom of the screen?


Your has probably blown fuse fl231, causing your convergence to go out. This is often a sign of a bad power supply. The fuse is located right next to the power supply. Replace the fuse and check flyback for bad solder joints. I fuse blows again, replace fuse and flyback transformer.

Picture looks like its 3D what is the problem


The D52W20 had an issue with solder joints around the flyback. When you take the back off the flyback is on the very left closes to the back of the tv and has a large red wire coming out of it. Looking from the top down you will see three small orange rectangles in a row. These are fuses and one of them is going to be opened.

All you have to do is resolder the pins on the flyback and replace the fuse and you should regain convergence.

Picture problems


check for cold solder joints around the flyback transformer and a open pico type fuse very close to it. they are rectangle in shape and ususually the one in the middle of the three is the culprit. The problem is in the pincushion circuit

Replaced flyback


often the old flyback will cause CP150 and CP120 to dome on top when the old flyback goes out. Check the tops of those two capacitors for doming. They are located on the same board as the flyback.

When turn on no picture and there is a high pitch buzz or frying. Then after a minute or two it will shut off by itself. Before thid happened the picture would come on slowly with a frying sound and then...


my first instinct in this is flyback transformer. or if it is three tube projector could be a high voltage splitter lines in picture sound like what is called retrace lines ... this is another indication of a possible bad flyback. high pitch sound is another sypmpton of a high voltage flyback transformer problem. WARNING televisions generate potental lethal charge. the device called flyback is used to generate several THOSAND volts. so be carefull if you take the back of any television. along with the flyback the horizontal output transistor possible could have failed. What type of tv is it? model
