Dear Experts,can you help please?we have a sony tv model kv-m2521u in for repair-tho old its a tidy low hours set and hopefully worth repairing.The fault is a collapsed frame,however at the time of writing we have no circuit diagram or information.Iv taken a look inside and found a hefty diode/rectifyer board ref-d612 pt no-ctu12s with all3 legs badly cracked/dry-jointed alongside 2 hefty 2200mu caps these all look at a guess tobe in the frame circuitry-can anyone confirm or help further-any assisstance or circuit information greatfully recieved-Paul.

Hi - my mom's sony tv - kv-27s42 ---- even after reading the manual I can not stop the closed captions from appearing - can you please help? Thanks! Tony


First, it is a older set.

Second: if the CC is coming from the set you will need the original Sony remote---Look under captions and either turn them off or to something other than CC1.

Third:If some kind of cable or other box is being used to supply signal to the set the CC can be coming from it! Yes, these boxes also have CC settings.

Look at settings in set first and in the box (if you are using one) second.


If this told you something you did not know rate this solution as very helpful as I do this here for free.

Our Trinitron KV-36XBR400 powers up then no picture


How old is this tv?More than 5 years old.Not worth it to repair CRT tv at this prices.Tries unplug,replug an hour later,might help,see if reset itself.U can buy a pretty good 32" LCD tv at $400 or less these day.It not heavy as the CRT tv,it alot easier to move the tv around the house or other locations.
