Re: Sega mega driveII AV problem

get yourself a quality scart cable first. Backtrack a loong time ago, my scart cables were much thicker than 4mm. Those thin ones are cheap and also perform as such.

Re: Sega mega driveII AV problem

interesting, almost looks like a cheap unshielded scart cable is used.

Re: Samsung pn51f5300af no HDMI

bad hdmi cable can do the same. Actually a new main board is surprisingly cheap for this TV.

Re: 60pb660v circuit

So pin 3 is the current sense pin. You better hook that one up. Pin 7 has no connection. You can leave that one off.

Re: AOC 1620sw powersupply fault

maybe the old 18V zener is just bad. Op never tested the zener that came out. Doesn't make sense that the monitor is working fine with 14V but not with 15 to 17V. Unless that original zener was bad,...

Re: Sony KDL-43WD750 Turns on, no display

Test the LVDS on the main board with an oscilloscope, while flicking the menu on and off all the time. That will tell you if the main board is good or not.
Check the Tcon that it is getting power...

Re: 60pb660v circuit

look at the second picture. Isn't the leg in question (pin 3) having a trace to a small solder point? Look where it goes on the other side of the PCB.

Re: 60pb660v circuit

just run a thin piece of wire from the through hole to the lC's leg. Put some conformal coating over it and be done with it.

Re: Sanyo DP50843 Won't power on.

No. It won't do that. If you have low 15V, I'd check the main filter capacitors on the PSU. I guess you have 2 problems to tackle.

Re: Sanyo DP50843 Won't power on.

so your main board isn't sending BLon nor the dim signals. These are getting generated on the main IC.

Re: Samsung LN40B500P3FXZA HDMI LOOSE, MAIN BD.QUESTION

well, I guess you answered the question yourself. Either you solder some new hdmi ports to the old main board, or replace the main board. Yes, the version of the main board does matter, since it...

Re: Panasonic TC-P65S2 no good HDMIs left - Suggestions?

you've got 2 choices. replace the main IC on the main board, or replace the main board. That's about it. There is no HDMI switching IC, as the HDMI goes straight into the main IC.

Re: Sanyo DP50843 Won't power on.

Disconnect the BLon and Dim pin from the main board at the PSU. Take two 1k resistors and jump STBY voltage to BLon and DIM. See what happens if you turn the TV on.

Re: 50PA4500 safety

that is why you are supposed to be really careful in the hot section of the PSU. Always take measurements first if you are not sure.

Re: Samsung UN55KU6300FXZA

Sounds like the main board isn't returning PSon and BLon to the PSU. So check that first. If you disconnect the PSU, well there won't be anything powering up. If you do make measurements on the hot...
