Power cord tp50h60


Look for the slot where it went thru the back cover--there will either be a 2 pin plug for it or two posts where it was soldered=hint it will be directly connected to the line fuse the set has--it is a polarized cord and must be connected correctly.

Your symptom sounds like a faulty capacitor in the vertical deflection circuit.
What you are seeing is called vertical fold-over.
If you want to fix this yourself and are handy with a soldering iron, it is not that difficult. Just look for a 1uf capacitor near the vertical IC. The vertical IC will be a black IC with straight legs mounted to a heat sink, generally in the center of the circuit board.
Note: Be careful when working on a television as the CRT and other capacitors can hold a charge that can be very dangerous.

I would recommend that you contact a local service center and see if you can get a quote for the repair. I would normally charge between $120.00-130.00 for this type of repair. The cost may vary depending on where you are located.

I hope this information allows you to resolve this issue.

1998 TOSHIBA TP50H60 THE COLOR WON'T MATCH, LOOKS LIKE 3-D MOVIE WITHOUT THE GLASSES. IF YOU HIT THE SIDE OF TV, SOMETIMES GOES BACK TO NORMAL.


Sounds like a classic convergence problem. most likely bad connections on the bottom of the stk's. If a repairman were to do this for you it would run $300-$500, if you were to do it yourself it would run less than $100. Bad connection on the vertical IC can cause something simular to this as well. If you need more help or would like to fix it on your own please let me know

Sony tv no picture only horizontal line


The probable defective part is the vertical IC. If changing that does not resolve the problem, check the capacitors in the same circuit. Also, check for the proper voltages at the vertical IC. If the IC is not being fed its power, it won't work either. I don't have a listing for your specific model. If you can post the vertical IC part number (LA7837 for example), I can list the voltages per pin.
