Question about Samsung HCL4715W 47" Rear Projection Television

1 Answer

HCl4715w Hi. I'd like to ask you a few questions about my TV as I paid the $15 and got nothing from the Dark Knight or whatever his name was. The TV is a HCL4715W. I bought it needing a power cable. I clipped the cable off a tube TV and used inline connectors to attach. The TV is getting power, clicks, but offers no sound or picture. Is it possible I did damage to the power board? The red LED light comes on and blinks, but still no sound or picture. How can I verify what my problem is? If you could assist me it would be greatly appreciated. I'm looking to find out if the replacement parts are worth purchasing, because I'm not sure of the quality of the picture and the condition of the projectors. Thanks for your time and I appreciate any info you can offer. Ryan

Hi , first thing is check for leaks coolant in all 3 tubes. It is a very common problem in Samsung projection TV. This means, if you have a leak, it makes no sense to repair your TV, isa big money for parts. Another possible solution would be convergence board is damaged, two STK 392-040 IC's number; also has associated resistors that can be opened or burned. Be careful, Try to open the TV and watch these two important details. If you have further questions, do not hesitate , I will be here.

TV won't power on

Disconnect the convergence board and see if the set comes on. If it does, and it probably will, replace the convergence board or the convergence amp IC's. Good Luck
