Pioneer PDP-434PU, no picture or sound

Hi All

This is a fourth gen Pioneer unit similar to the PDP504.

I've downloaded the manual but I'm having a hard time deciphering the "code"

When I press the power switch the red 'standyby'...

Re: Haier L42B1180 - solid blue light, EEPROM problem

Thanks Yokoono

The sticker on the mainboard has these numbers:

222-110505001
TV 222-110418005-v420h2l01

Where would I find the panel number and can you point me to where I'd look for a...

I'm reading it on the board, power off, with a clip.

Haier L42B1180 - solid blue light, EEPROM problem

So my reading on these forums suggests that a HAIER with a solid blue light that won't turn on probably has a bad EEPROM at U11.

Shop jimmy doesn't have one for my main board (looks the same but...

How do you remove/install LCD panels from TV?

So, yesterday I dinged an LCD panel on a rack and cracked it, the TV was a write off. I noticed there was a LOT of flex in the glass as I took it off the TV and turned to put it on the rack. I was...

Re: Panasonic TC-55CX650U

OK, I got this one fixed. Turns out it was a couple of lamps and I learned something new.

I thought that if I had bad lamps that by removing the connectors to the backlights I would remove the...

Re: Panasonic TC-P50GT50, Won't turn on.

Thanks R_J

I had a chance to get back at this set again last night. Your instinct was correct, there is no signal from the main board when I press the power button.

I followed the stby power in...

Re: Panasonic TC-P50GT50, Won't turn on.

Bummer. The STBY circuit is fed straight off the PFC circuits on this one and the block diagram indicates the PFC works in stby so long as it detects AC. I was hoping it would be that easy.

I've...

It's officially Panasonic week here at JRElectronics LOL I've received five in a row, one repaired and four left. I don't normally even repair TVs but it's bad PR to turn away the work, I'm...

Re: TV repair workshop advice please

I would arrange my test gear and tools to be stationary and the tables or desks that you put the TV on should be on wheels, that way you don't have to carry the TV as much. It would be great if we...

Re: Panasonic TC-P42C2 - No HDMI

Hi Unspun01

I replaced BGA ICs for years on motherboards and was pretty good at it but when boards get below $100 the profit is too small and I sold my IR machine and all of my re-balling stencils...

Re: Panasonic TC-P42C2 - No HDMI

Re: Panasonic TC-P42C2 - No HDMI

Then I started to trace out 5V on pin 18, this is a reception point...

Re: Panasonic TC-P42C2 - No HDMI

Thanks Unspun01, I'm sure the TP-42C2 is just the Canadian version of the USA TP-42U2 so the manual should be identical. I'll try to work through all these regulators tonight and see if I can find...

Re: Panasonic TC-P42C2 - No HDMI

Hi Budwich

OK, I understand now. The source works, it's an old Boxee Box and it produces a signal on the set on the other bench, this is also the fault the customer brought it in for.

Re: Panasonic TC-P42C2 - No HDMI

Hi Budwich

Only two HDMI ports on this model and neither one works.

I'm going to have to spend an hour with the service manual and my meter looking for a missing voltage line.

Re: Panasonic TC-P42C2 - No HDMI

Re: 40E200U1 - Anyone need these boards?

Customer refused quote and abandoned it.

Re: KRP500M/Pro101FD, trap switch? Manual?

Re: KRP500M/Pro101FD, trap switch? Manual?

Well, that's sort of the point of the question Pete. I can't see it either and I don't know what it looks like so I don't know if I've missed it or if it doesn't exist on this set.
