Re: Vizio VT470M goes black after couple of minutes (no picture, yes sound)

Yeah, I get backlights but no image. Could it be just a matter of replacing caps? Are you just going to try replacing them all or are there a certain number of known problematic ones? Thanks!

Re: Verizon VT470M Service Manual

A mainboard swap worked for me... but after a year the problem reappeared. This is that mainboards are hard to come by and usually expensive (over $200).

So last year I bought this TV on craigslist for $100 with the same exact problem with the intention of repairing it. I would turn the TV on, the Vizio logo would appear, the TV would work normally for a couple of minutes and the POOF, screen would go blank but the sound would still work.

So doing some research I figured it was either the T-Con or the main board that was at fault. Being the cheaper part, I replaced the T-con board first and nothing. After that I bought a new main board (CBPF9D1KZ6) and voila! That repaired it and it worked happily ever after...

Until...
