Thanks a lot for your support Terryfic!!!. We could fix the problem with a new board. Although the board cost almost 200 bucks, was the best way because the new board seems to be better designed for the temperatures it will wistand.

Thanks a lot again!!!!!

I think you have a fault on the chroma board and on the picture frame board. If you can trace it yourself try these two locations otherwise call out a competant technician. hope this helps.

Convergence issues

if youre having convergence issues with your samsung HC-P4752W you need to replace both convergence ICs numbers STK392-010 they are available at the following link and they provide free instalation instructions with pics so you can do the repair your self and they also give free tech support in case you need extra help. Its an easy repair takes about an hour from start to finish, Changing the convergence board wont help as the Convergence ICs are located on the sub deflection board and thats about 400 to replace the board compared to 50 to replace the ICs. Heres the link.

Samsung HC-P4752W rear projection television We

the convergance amps have failed you need to have them replaced there are 2 of them and some resistors may be affected. the cost of this repair can reach $350.00 depending on the tech you get. this is the most common failure in rear projection TVs. the convergance amps work very hard and are bound to fail. they also have very large heat sinks to keep them cool. heat is the biggest enemy of transistorized ICs.
