Hi, on most of the CRT(glass picture tube) TV the common failure area is the deflection or power supply board(s). If you're TV is a 32AF42(what shows in your post)there is a remanufactured board available at partstore.com. I suggest you take a quick check at the deflection board in the TV set and try to determine if this is the board to replace, horizontal output transistor, flyback or horizontal out transformer, power supply regulator are some of the components to check. good luck!
Any malfunction associated with a flashing light usually indicates a
circuit problem or defective component. Unfortunately, the days of
taking off the back cover of your TV and replacing a defective tube or
fuse are long gone. Proper servicing will require troubleshooting
procedures that can only be performed by a qualified electronic repair
facility or professional television repair person. Ask for an estimate
and a realistic appraisal of whether the set can be adequately fixed.
Depending on the age and condition of your TV it may not be cost
effective to repair.
sounds like a sticking tact switch. an engieer would isolate the sub-panel that contains the volume and the manual programme up/down switches and then operate the TV using the remote control and see if this eliminates the problem
Sounds like DRY JOINTS WITHIN DFS MODULE.
This is a pcb within a rectangular metal screened box on the left hand side of set when looking from the front.
Will need resoldering be carefull very fine print will need decent soldering iron with fine tip & poss magnyfying lamp to aid looking.
If your not at all sure take to repair shop.
This TV is nice set has one of the best crt pictures you can get.
TRY ADJUSTING THE SCREEN CONTROL ADJUSTMENT AT THE BOTTOM OF THE FLYBACK TRANSFORMER.THIS SHOULD REMOVE THE RETRACE LINES AND ANJUST THE HASY LOOK TO THE PICTURE IF NOT YOU HAVE A BAD CAP IN THE SCREEN CIRCUIT .LOOK FOR A 10MFD/250V CAP IF FEEDS THE NECK BOARD ATTACHED TO THE PICTURE TUBE 200V DC.
