Hi, my tv hc-p4241w was ok but one day, the

Look to see if any coolant fluid has leaked from any of the CRT's. This is a common cause of multiple component failures in these models. Look real close at the CRT mounting bracket, the wires coming from the CRT's and look at the particle board below to see if you can see any staining or puffed up wood particles. My experience with the Samsung bds is when you have a multiple compoment failure due to fluid leakage it is best to replace the boards instead of component level repair because other components will fail at a later time. Coolant fluid is real hard to spot since it is ultra clear. Hope this helps.
