Question about Televison & Video

3 Answers

When the set is turned on the top 4.5" of the screen appears to have a milky white substance covering it. It is somewhat transparent (more opaque, but you the characters behind (beneath it) are hard to discern. This problem increases with each set turn-on. Is the tube shot, or can it be remedied?

    This is not for a projection TV- the affected set is a regular 27". The affected area is 4 - 5 inches and growing.

    It is a JVC, Model # AV-27230

    Hi Jamie- I've never done this type of repair-would it make more sense to take it to a repair shop?

  • searlesjs Jul 07, 2008

    Hi Jaime- how much do you think these repairs might cost? Thanks,John.

  • searlesjs Jul 07, 2008

This could the problem with weak capacitor or the weak picture tube... IT may cost you 50 to 300 $ depending on the problem.....

If you plan on replaceing the parts yourself less than 100, if you take it to a tech the price can go anywhere from 200 to 500

    There seems to be a capacitor(s) that are becoming defective nearby the vertical output amplifier.

    The picture tube is fine as this defect is located in a different area of your TV circuitry.

  • Jaime Hernandez Jul 07, 2008

    The parts that need to be replace are label as C424, C425 and C434 and they are located near IC421 with the following makings LA7840 that is mounted on an aluminum heatsink.

    NOTE: Before you do any work if you are planing to, unplug the TV for at least 12 hours to allow the high voltage capacitors to drain their charge.

    Let mek kow if you require further assistance.

  • Jaime Hernandez Jul 07, 2008

    If you have not done this kind of work before is best if you could take it to a repair shop but if they tell you that the CRT(tube) is bad just to charge more, tell them more or less the parts that they will need to replace.

    Good Luck.

  • Jaime Hernandez Jul 07, 2008

    I would say that a fair price to pay for the repair should be about 1/3 of the price of the TV.

Fixing the picture in my Philips rear projection tv


As far as mostly red--turn color to zero and examine screen--if not gray or black and white it may need the screen controls adjusted.

Dark---with back cover off clean the three lens this model has--they are the light source for your picture and if dusty picture will be darker and somewhat dull looking.

Answer is based on brand/model number listed here.

Hitachi RP CRT Gone Red On All Inputs!!!


I want you to do a simple visual check of something that will tell me what the problem may be.

Go to a channel that is in black and white--old movie and tell me what color the screen/picture is.

You can also turn the COLOR in the customer menu all the way off and look that way.

What we are trying to see here is if TRACKING is set correctly or has changed. If the screen is somewhat to medium reddish it may be an adjustment outside of the customer menu.

Let me know what you find--I have seen several of these where the black and white picture was somewhat red--the idea is it should be as close to black and white as possible--if red is the predominant background color the picture will look reddish.

If this has helped and you confirm the red instead of black and white picture--I can tell you a easy way to adjust this.

If this information told you something you did not know and helps you rate this solution as I do this here for free.

Milky white picture


Could be a bad resistor on the screen amp board causing excessive brightness. this will wash out the picture and cause fine diagonal lines in the picture. Without seeing it this is only a guess.

According to Sharp it is a software problem. Engineer came, installed software update ,10 minute job.....TV worked fine for 1/2 day unfortunately: Then images turned black and white in all channels TV turned itself off, and stanby and OPC buttons started flashing. When TV came back on its own 10 mins later , screen had 2 large square staines superimposed in image (as if it was a burnt screen)...Engineer will be back next week...all quite sad really for a new TV.....will keep u posted

Light engine issue I would say, is it somewhat transparrent? if totally black might be something else but more than likely will be a light path issue inside the light engine.
