Question about JVC PD-42WV74 42 in. Plasma EDTV

1 Answer

I have the same problem with my JVC PD-42WV74.

It powers on I get audio but no video and after a few seconds it clicks and the green power light starts flashing.
This same problem occurred in 2004 and I had the unit serviced under warranty. At the time the service guy said this was a known problem with this unit.
Does anyone know anything about this generic problem with these units.

The most likely the TV has a power supply related problem. The most common thing to go out is the circuit board that supply power to the screen. Commonly called a Backlight Inverter Board.
I can't say it's 100% the problem because I can't actually look at the tv over the internet.
If by chance the TV is still under warranty, go that route.
If not under warranty and If you have some electronic experience, you can purchase a Service Manual over the internet and diagnose the source of the problem and fix it by soldering in the new part. The Service Manual will give you circuit diagrams, test points, and part# lists. Usually, cost under $20.

I hope I shed some light on the subject for you.

JVC PD-35D30ES Vertical lines - problem


Hello
Check its power supply board for any damaged capacitors. Replace them if found or suspected. Take special care to main filter capacitors. check all the output voltage smoothing capaciotrs too.
If all are OK, and still the problem perists, replace the power supply board as card basis.

JVC PD35D30 Plasma won't turn on anymore...


Yeah, I was going to suggest power supply issue. Plasmas IMHO, are not worth spending the money to fix. Its the reason why they are so cheap these days in comparison to LCD's. I had a 50" Samsung Plasma that went out on me within 2 years (E Buffer board and XMain problem). Its not about the manufacturer but more about the Plasma technology. Do a few searches about plasma and you will find a lot of problems with these tv's. Id say cut your losses, sell the TV for parts and buy a more reliable technology

Yes, you are correct. there are a few component issues on the power circuit board that will need to be replaced. the mani component will be the capacitors and transistors.if not repaired soon, this unit will completely stop working.

JVC PD-42WV74 Plasma will not power on ?


I believe that this monitor will not work unless you have the cable from the media center to the monitor hooked up, I have all the parts from one of these due to the screen being defective on one of my customer's TV like yours. I have the connection cable that I could sell for $ 20. + Priority shipping of $5.65

JVC PD-42WV74 tv turned itself off and unable to turn it back on. Green light blinks on receiver and TV.


Unplug the TV set, after a few minutes, plug it back again. If you are lucky, the TV will be okay!
