Question about Panasonic PT-51HX41 51" Rear Projection Television

2 Answers

Think this is worth fixing?

I just received (free) a broken Panasonic 51" HD rear projection TV... it plugs in, powers on, and displays a picture. However, the blue bulb has been removed and I am told that the previous owner paid $50 for diagnosing the problem - the bulb allegedly needs to be replaced. However, I don't feel comfortable buying a new bulb and crossing my fingers that this is in fact the issue.

I've searched online and it seems that the common problem with these things is the "convergence" circuitry/chips needing to be repaired/replaced:

My question... what can I try (without bringing it into a shop) to further diagnose? Is this worth pursuing?

Model Number
PT-51HX41E

Chassis
AP820

Thanks!

    When I plug the TV in and look in the back (panels removed), I see a red and green bulb producing what you see working in the pictures. So... yeah, I'm pretty sure it's the blue bulb that's out.

Have a PT-51HX42 and the color will not get right no matter what I do. I have no green or red and it looks terrible, especially in HD. I was told I need a new bulb. I tried adjusting convergence and that did'nt help. What do you suggest?

Trust ME when i say setting convergence after doing repair takes alot of time to do /you can damage set if you do not have service codes and values/ you also must have the hand unit that comes with set in order to even get into convergence circuit, call your repair shops ask if they have a good blue tube for set and how much would it cost to repair?ARE you sure blue tube has been removed from set.?

Try disconnecting all of your HDMI cables and plugging the power cord of the TV into another wall outlet. If this resolves the issue, you may have had a small power surge from either your wall outlet or one of your source devices. It is recommended to connect your TV to a surge protector if you haven't done so already.

To verify that the tuner is the problem, move the cable from the second to the first. If you don't get a signal, the tuner is bad. The main tuner is part number 859843000 and is available for $47.38 from tritronicsinc.com

Sound but ni picture


I dont think that TV has a bulb it uses CRT's

You cant get CRT's any more. Sounds like the capacitors in the power supply are week and are takign time to charge thats why it takes a while to get a picture.

Not worth fixing
