The coolant has done 1 of 2 things. (1) most likely it has shorted components on the circuit board. (2) also very likely that the affected tube has cracked without the coolant and thereby shutting down the set.

Have a tp50f60 toshiba tv, blue not lined up, coolant leaked out of blue, also got coolant on hands should i be woried


Yes, the clear liquid is Glycol and it is like antifreeze but ten times more toxic. This is the reason now most landfills or dumps will not accept these type of sets for disposal.

The chemical is absorbed directly into your body via your skin.

Wash with soap and if Glycol has leaked get the set out of the house as if it gets to the bottom of the set etc a animal or small child could be harmed (I have seen it kill dogs).



Let me know if you have questions or concerns.

2 PROBLEMS


Your two problems are different . Your tv shutting down is not due to the tuners . First thing i would check is to unplug set and take the back off . On the left side is the board with your tuner on it . Look on that board to see if these is any liquid buildup on it. One of your picture tubes could be leaking causing set to shut down . This can also be causing your snowy picture problem as the liquid has started to spread . The metal braket above this board is where the liquid starts to trickle down from . Use a flashlight to see . If you see no liquid then you have hv sweep problem which would need to be checked out. If you still want to get a board www.ptscorp.com May have your board in stock . Good luck

Leaking liquid


Sounds like your Blue CRT is leaking coolant.It will affect the hue for sure and it will also destroy your circuit boards as it is corrosive. Clean any coolant that has spilled onto your Chassis before it causes corrosion. You can buy coolant to replace this, however you will need new seals. This is a proceedure you may be able to handle if you are dilligent and pay attention to details. Replacement coolant can be purchased at the following Link
http://www.matelectronics.com/ or this link http://electronix.com/
The seal will probaly have to be orderd through RCA, I am not sure if the links mentioned carry the seals or not you might give them a call to inquire. If I can be of any addittional help let me know.

Is the power light staying on? If so press imput and menu together for 5 seconds to see if the set will blink a 2 digit repeating code. If that doesnt work. Check for CRT coolant leaks on the boards. This seems to happen alot as do faulty capacitors. Coolant leaks will be located on the chassis directly under the tubes they can cause corrosion and prevent your set from starting especially in the VS models.
