Re: Picture quality

With age the quality of a tube set is decreased. But first when was the last time your lens and mirrors were cleaned.

Poor viewing quality

By poor color quality, do you mean that if you turn the color control all the way down, the black and white picture is more like black and red, green or blue - or do you have a good black and white image? If the B&W image is good, and the TV is an old (8+ years) one, maybe the mirror inside the set needs a good cleaning - especially if there are smokers in the room. If you have a B&W picture that is tinted, then you may have to go into a service menu to adjust it back to a better picture. Hard to guess the problem without more specific description of symptoms.

Poor picture quality. Picture also tends to curve

The curving is caused by bad digital convergencr chips (2) located on large signal board. They need replaced along with blown pico fuses and the convergence resistors. Chips are huge compared to a regular IC. 2" x 1.5" and they will be bolted on fairly large heatsinks. Cloudy picture is most likely the coolant needs replaced in the picture tubes. This needs to be done approximately every 5 years.

Poor picture quality, the picture is blurred and

You have problem with convergence. Have you tried adjusting in the users menu. This is a common problem in this type of TV, usually two convergence amp need to be replaced and sometimes sets of resistors are also to be changed.

Poor picture quality

Hello Paul. I have this same monitor, but rebranded, Access the service menu with the remote control:

With user’s RC
1. Power TV On
2. Press Menu button and call up User OSD Menu
3. Select Sound-> Balance
4. When Balance value is “0”,Enter 0->5->3 ->2 in sequence.
Note: If necessary, re-do number keys.
5. Factory OSD appears.
6. Press the standby button then AC turn off and restart the TV, which can exit factory
OSD menu.

Now you will be able to change the values for Red Green and Blue channels. I also hated this TV, but after adjusting the colors it's looking great! Hope you could fix it too! :)

Poor pictre quality

This set has 3 CRT's (picture tubes)
Remove the back bottom cover
Clean the CRT's with windex and a soft cloth.
(Find the Screen/Focus block)----Remove front grill cover and panel which covers the Screen/focus block.
Cover 2 crt's and adjust the focus control for remaining crt---(using the convergence pattern in the menu for the set)
adjust for the best focus.
cover that crt and move on to the next crt using the same procedure.
After setting the focus on all 3 tube's you will have the best focus possible for this set. If picture is still bad, you have bad crt's and the set is junk.
Cost to replace the CRT's is enormous!

Picture not sharp needs adjustments

its more than likely the CRT coolant if the picture quality is not very good. If the image appears 3 D thats another situation. Let me know if you need more assistance.

Black/Green Distortion - Picture Quality - Wharfedale

This is no solution but a point in a probable direction.

A tech guy told me ALL the LCDs they have seen in their repair shop have "swollen" capacitors, this is due to voltage instability. Lowering the internal voltage regulator and replacing the swollen capacitors (which eliminate noise) apparently restores the LCD to new working quality. Without actually "seeing" my problem the tech said that should repair it. I have not tried this yet but eventually will begin that way.
