The problem is, this part is dedicated to your set and it is a manufacturer part (OE) only unless it`s a common set. The next problem is that the LOPTX has got to be installed by an engineer who has to set it up as regards Screen feed and Focus Pots. You could try CPC in Preston, Charles Hyde in Pocklington or Willow-vale Electronics in Manchester but I think you`ll find that it`s a closed shop and they will demand you take it to a dealer who has an account with these suppliers. I came out of the trade four years ago, I`ve got all the necessary qualifications to fit these parts, but they won`t supply me because I`m not an account holder or a business where suppliers like these want to see your accounts for the year and make sure you have the qualified staff and funds to fit and pay for these dangerous high voltage parts. Good luck, Ian

I have a kv-32ls60u Sony TV. It blinks 5 times


The most common failures are the flyback transformer assembly and sometimes some of its support components, and or there is the possibility of a short in the CRT electron gun. In either case, the power supply is going in to protect mode, and the uPC is sending this flashing error code to the front LED.
I have no idea if the flyback transformer assembly is still available, but I am very sure the CRT is no longer available. In any case you will find the cost of servicing your set to be expensive for its age. The last time I checked, the cost of the CRT exceeded the replacement cost of the set.

The convergance menue is gone. I need to adjust the convergance badly but it is no longer in the menu


You need to resolder the flyback transformer and replace fuse FL221 off pin 11 of the flyback transformer. The convergence power supply is not coming on so system control thinks a convergence circuit is not installed.

RCA P46920 TV will not turn on, it makes a beeping noise.


Shorted horizontial output transistor q14401 -I think- and bad flyback transformer(high voltage transformer).The noise is the power supply starting and shutting down very quickly because of the shorted transistor.Very common problem,but some of the flybacks are no longer available from RCA.Sometimes you can use generic but questionable life on some of these.

36" RCA- loud whine/squeal when it is plugged in, otherwise no power.


The HOT Hortz output transistor has gone home, 99% of the time from a faulty IVHT (Flyback Transformer), very common on the ctc187cl* chassis. The factory Flyback is no longer available, I have had problems finding an aftermarket one to replace it with.

The HOT is a BUH517, but you can also use a 2SD5129. It is the transistor mounted on the siler heat sink with a metal clip rather than a screw, just in front of the flyback.....

If you replace just the HOT, most of the time you will get a rapid arc (27,000volts - BE CAREFUL!!!) from the lower (yoke) post on the flyback. If the flyback is shorted, It may also just burn out the HOT and go right back to "squealing"....

Good luck finding the flyback!!!

JVC AV-27230 27" TV - Won't turn on - repair guy says parts no longer available


He probably means flyback transformer. They are harder to find unless you are a service provider. Then they have access to these parts. Generally it's a cheap part, but often servicemen can mark it up quite a bit. Try another service guy.

Natura Hitachi 36in TV - Not turning on.........


Check the flyback transformer for cause of the odor . If it is a cap look for a cap that is buldging at the top of it . The flyback is the transformer with the red lead going to the picture tube . You might see it is cracked or a tiny hole in it . Good luck
