Trying to find the Thermal Reed Switch

I know the Thermal Reed Switch ( made by Tokin pt# TRS5-60BLRU) is bad. Where can get it? I checked with Tokin and it seems like they are part of NEC. However they only sell the part to big distributors. Anyone know of any distributors that will sell me just one?

Get the board location number and I can get you a Mitsubishi part number and the part can be bought from Mitsubishi.

Panasonic pt 50lc13 Ballast update done Bulb blew out just replaced and now the amber ( yellow flashes twice ) every 5 seconds how can i check the door lamp switch? is it just an open closed switch? thanks...

The door switch is in the front. The switch is triggered when you put the lamp door cover back on. It is a switch thats spring loaded so when you put the lamp door back on it automatically presses the switch.
If you have any other questions please feel free to ask.

When I turn the power on all I get is a blinking green power light and nothing else. The lamp is new.

Have you checked the thermal Fuse that is located right above Lamp? These sets had problems
with Thermal Fuse. Is all of the Fans working ? Lamp Fan?
Ballast board is what powers Lamp on. You need to also check 2 thermistors,they are known to be bad.

I have a panasonic pt-45lc12

If you are not a tech you don't want to mess with the voltage that feeds the lamp. The vibration of moving the set can cause the lamp to go bad. blinking LED is usually a sign the lamp is bad. It is a good Idea to open the lamp door and then close it again to make sure the door switch isn't the problem

Overheat led blinking

Did you ever get a answer to this question? I have a hitachi 50vs810 with the same problem. I found the same sensor "tokin ohd3-90m."
I ohmed across mine and it shows open. I then held my lighter under it and it stayed open. I suspect this part is bad so I tried jumping it out. No change. Still have the same blinking temp light.
So... in the end I don't know if I tested it right or not either. Good luck and let me know if you learned anything that can help me out.

I would suggest to check the solder joints again and also nearby the STKs area, check the low values resistors solder joints as well.
It looks like the ICs are overheating.
Did you apply enough thermal compound before installing the ICs?
Try placing a fan close enough to the ICs, just to see if overheating is an issue.
Good Luck.

Your TV most likely has a Convergence Chip Failure ( common problem )

Here are some of the most common symptoms and example photos of a convergence problem

  • Screen looks 3D
  • Colors don't line up
  • One or more colors can't be adjusted when using the convergence menu.
  • Screen is bowed or warped.

You need to replace the convergence chips and convergence resistors. Check the site They have put together convergence repair kits for most models.

The kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, thermal paste, etc. Everything you will need to do the repair yourself.

PT-40LC12 fuse problem

I went here for a tech manual for the Panasonic tv.
then ordered
Manufacturer: Panasonic
Part Description: FUSE
Part Number: LSJA0411-1
it was mounted to the case that holds the lamp. had to remove the back panel, etc. Also think I had to splice in the fuse or something. was a while ago.

mine is broken again. this is getting old between lamps and repairs.
