Samsung LE40N73BD sound but no picture?
Samsung LE40N73BD sound but no picture? The screen/panel is LTA400WT-LH2 and the power board is BN44-00134A Rev 1.5. I replaced the caps that were bulging and it worked fine for a day but now the screen is black. I suspected it was the backlight/inverter but this screen doesn't have a conventional inverter. Any ideas, thanks. -
Re: Lvds
I work for the company I got it from. The tv only needed a couple of caps replaced and then worked fine from cold and worked fine for 8 hours so this leads me to believe the screen/panel is good. The tcons are the only difference. There are extra connectors on the 4046fa7m4c6lv0.4 could I need an extra cable from main board to tcon for this configuration?Leave a comment:

Re: Lvds
The company I got it from salvage parts out of LCD tvs and they had left the tv to soak for 8 hours and no tab faults. The tcon in the HC01 is a FRCM_tcon_v0.1 and the HF01 tcon is 4046fa7m4c6lv0.4 I haven't checked compatability with the main board.Leave a comment:

Can anyone help? I have a Samsung LE40A686M1F which has a tab fault. The panel/screen is a LTF400HC01. I got a replacement screen which is an LTF400HF01 as I thought it would be compatible. I also had to get another T-con as the HC01 has 4 tabs from panel to tcon but the HF01 only has 2. I am now getting tab fault like symptoms even though the screen had been fully tested. Has anyone had experience of this or have any suggestions? -
Re: Faulty NAD c370 amp
Excuse me for being a novice with amps. I fix LCD tvs and thought this would be an easy fix. I will look inside it again tomorrow and get back to you. Thanks again.Leave a comment:

Re: Faulty NAD c370 amp
Thanks for your reply. I switched inputs but still the same problem. I have taken the pot apart and cleaned it but no joy. Do you mean clean out every control switch? I read somewhere about the caps in amps, could these be the problem? They look fine.Leave a comment:

Faulty NAD c370 amp
Hi, I wonder if anyone on here could help me? I have a NAD amplifier that sometimes loses sound to one speaker. I have changed the speaker and still the problem persists so it is the amp. I have cleaned the pot and visually checked the caps but no joy. Does anyone have any experience of this problem in amps? -
