SOURCE: sound ok but no picture on a 42 inch. lcd tv

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 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.

SOURCE: 42 inch lcd tv.its a rca. the screen is damaged.

There is NO picture tube on an LCD set. If the screen is damaged it will make more sense to buy a new set rather than attempt a repair.

SOURCE: RCA LCD TV INVERTER BOARD

I have a new power/inverter board for a L32HD32D RCA 32" flat screen LCD TV. Make offer, 1-907-225-2337 I'll ship it USPS in the box it came in.
LS2HD32 CEG379B CAJAID, CAJA4465 1114363 are some numbers on the package it came in. You might try LPS#1 on the ribbon cables & their video board connection for the LCD by opening the back 4x5" pannel in the middle & clean reinstall them ? That's what fixed my TV, maybe. So I don't need the board now. It's only about a 5 minute job to clean the 2 ribbon cables.
Sincerely Bitdog

SOURCE: i have a 42 inch rca tv model WB22YX5 componet inputs dont work

Sometimes, these inputs get damaged by ESD, or stray voltages, and become damaged. You may just need to give the set a reset, unplug an leave for 5 mins or so, and try again, if still no go, see if there is anything, in the troubleshooting procedures, that can help. It may just be a board replacement, If you decide, to get it repaired, please first contact RCA head office, and ask for a referral, to an authorised service center.

SOURCE: 42 inch rca lcd tv says unusable signal

This is a very common problem with these models.
The problem is very likely a fuse that has blown, if the following is true:
No Video on any input BUT HDMI and
No Audio at all.
Purchase a fuse, these are freaking tiny from digitalkey.com or mouser.com F1455ct-nd
Pull the back off of your unit
Pull the cover off of the PCB housing. It is the box that contains the hook ups including the cable tuner.
The silver box that you screw the cable to is where you begin to look for this fuse.
About two inches behind this silver box is some numbers printed on the board 7c32 and partially obscured will be 1c33
Using a big magnifier look next to the numbers listed above, you should see a tiny rectangle fuse with an F on it.
This F fuse is a 500ma fuse that is too small for the load
The fuse listed above will have a G on it. It is a 750ma fuse.
Call the repair shops in your area, tell them that you know the problem, have the part and you want to know how much the bench time and labor will be to repair your unit.

My RCA 42 inch TV turns on but I see nothing but different color lines on the screen and no sound.


Lines on the screen usually is a problem with LVDS board, panel or the ribbon cable to the panel. Set should have audio though. the main board processes both audio and video but will not produce colored lines.

I am attempting to attach a Samsung Sound Bar to my 42 inch LCD 1080P Polaroid Television. I can not seem to get sound from the Television connected to the Sound Bar. Thoughts?


Connect the audio out RCA jacks (white and red) on the TV to the white and red RCA input jacks on the sound bar for analog stereo sound or connect the black digital audio output jack (typically optical) on the TV rear panel to the sound bar's optical digital audio input jack for surround sound. Use an optical cable. There may be some user settings on the TV for audio.

42 inch lcd tv.its a rca. the screen is damaged. picture tube is out. how much will it cost?


The cost of a new screen is proportional too the retail value of the tv. When the screen is cracked its overwhelmingly expensive to purchase, then an additional cost to install it. You may want to look into selling that tv for parts. Other than that, you may as well buy a new tv compared to the cost of a new LCD screen.......
