I have an old Toshiba portable Model no 1510RBT and I cannot program cable into it. Can you help?

Sounds like a tuner issue. alot of the older sets can develope solder cracks where they mount to the chassis. Check the solder joints, and if its the twin type tuner check the pins that connect them together. Alot of times resoldering can straighten then out. Hope this helps. Let me know if i can be of further assistance.

Toshiba 42WH36P rear projection TV has wavy lines

the problem is going to be a bad NEXT HYPER UNIT module. this is the digital scan card in the tv. try using the componenet inputs and if the tv works ok then you know that the HYPER UNIT is the problem. the reapir process for a "do-it-yourselfer" is too involved and would recommend a serivce center for this repair.

dont know about warranties but horizontal lines means your horizontal frequency which runs about everything has drifted off sync and if too high or low it will activate shut down circuits in high voltage and power suppy, even causing HOT transistor to short. good luck and call a tech.
