Blue crt kp-51hw40

Hello again, i was wondering if you posted the instructions on getting rid of the internal short in the blue crt on the sony kp-51hw40 and also i found a place that would give me a remanufactured blue crt but they need the old one first so they can take certain parts off it and i guess rebuild it but my question to you is, Is it possible to remove the crt myself or do i need a repair man to do that..?

Sony KP-51HW40 51 blue crt


Check the info from this website on how to remove shorts from CRTs. This is not a DIY for sure.
The CRT you can remove it yourself, just be very careful when removing the high voltage wire that is connected from the HV trippler to the CRT anode. The CRT anode cable stays with the CRT.
Good Luck.

Flashes blue and then the tv shuts down


The tech is correct about the internal short inside the blue CRT. There is a way to remove that short by applying a small amount of current to burn the short but that might damage the CRT even more. At this point the CRT needs to be replace.
I will post the instructions on how to remove that short but you will need to have a good regulated power supply and limit the amount of current to 1 to 2 amps.
