My 32" won't turn on

Check its main power supply regulator section circuit for defects. Check and replace damaged component/s.

Quite possibly one of the heat sinks has come loose or a power supply cooling fan has failed.
Have you tried blowing it out using canned air?

This is an indication of protection error and might require attention of a qualified service technician.

Here is the low cost solution for it. http://daitechca.ipage.com/store/page3.html

good luck!

It appears to be a 32 inch.

Some questions:

Does power light come on and if so what color when set is off?


Were you having any problem before where you had to turn set on several times to get it to come on and stay on?

I am here to help you.

Hi,


The sound was came from the clicking of the relay. This kind of symptoms is an indication of out-of-regulation condition on the power supply section. This is caused by faulty electrolytic capacitor. It will dropped the supply voltage and will trigger that kind of symptoms.


Faulty electrolytic capacitor mostly has a physical indication of fault like bulged/dome at the top and can be easily identified. See sample picture of faulty electrolytic capacitor below.




capacitor with bulged/dome at the top.


Check these parts on the power supply section. Once found, replaced it with same capacitance and working voltage which is printed on its body itself. Click this LINK for more info regarding electrolytic capacitor.


If you don't have necessary tools and test instrument and can't troubleshoot the unit yourself, I would advice you to look for a qualified TV Technician to isolate the faulty parts.


Hope I helped you.

Have a nice day!

Thanks for using Fixya.

turn off then wait 2 min, then turn back on.

Hi,

In most cases this cannot be economically repaired... the cost to repair would be more then the calculator is worth...

Check all ground wires and make sure they are tight. Start at the battery, starter, solenoid switch.

It could be a faulty cartridge. Have you already tried inserting a different known working cartridge? If error continues to pop-up even with a different new or a known working cartridge, then it could be a hardware problem. Try to contact Lexmark technical support on the phone for additional assistance.
