It was the first one with the smaller, newer design, but still top load. |

I have a 2006 Sharp LC37G2X 37" LCD panel which was made in Japan & it's still working 6 years down the track & the only thing to have went wrong in all that time was in the AVC box when a SM transistor & Zener diode went duff causing the main power supply in the AVC box not to switch out of stand by.

Was that set that clean, as found? Looks like low hours set.

Yes, it really was that clean inside

That chassis looks really familiar, back in my TV servicing days, we had a line of sets branded AWA/NEC and Samsung with pretty much the same bottom PCB as in this one. They were actually pretty reliable and did give a good picture so no surprises with this one giving a nice result.
One problem though with these and it looks like your set has then as well, is the rubber wedges that sit in between the tube and the yoke go bad. The rubber goes hard and takes on moisture which then corrodes the copper windings and causes the yoke to short out. I'd pull them out and check to see what its like underneath, you may be lucky with yours as the set is still going. If they are going hard or look crusty don't put them back. I think the other issue was a high voltage electrolytic cap in beam limiting circuit from memory it was a 4.7uf or a 10uf at 350V - this would leak and you'd get a bright white out raster with fly back lines. Nice find, the set looks as though its got some life left in it Cheers Glen

Nice that the set still works.
I have a real soft spot for sets like this one. Nothing spectacular about them, just good every day watchers, and the cabinet styling while not a thing of beauty sure beats the black, charcoal gray, and silver sets that followed. Always nice to see a red or green LED channel indicator in the upper right hand corner. |

Hey guys,
I just finished fixing one of these. Intermittent shutdown: After warmup, the set will shut off with the channel indicator still lit. The board is poorly soldered at points. Possibly has been repaired before. Heatgun tested a few actives in the secondary flyback supply, and sure enough I had a regulator coming off the tuner supply which looked cooked. Very good cheap sets though! D1785 Last edited by zenith2134; 07-24-2022 at 11:50 AM. Reason: Added part # |

That is pretty cool old tv and the only thing I have had brands caphart was a extremely cheap record player and radio. Unfortunately the main output transistors we're shorted and the motor was broken do to bad bearings and used the main power switch out of it to fix my 1986 zenith tv. I got zenith tv and caphart both from my grandad along with some other things. Aslo I have a Dell monitor from the 2000s and it has Chungwha CRT

That's a far cry from the CTC-4-ish only known surviving Capeheart CXC-13 color set I have or the 411 turnover changer console I've got.
