SOURCE: sony bravia lcd tv has no picture and colorful

Without looking at it I would guess that the LCD Controller on the LCD panel is bad. The only way to replace it is to replace the LCD Panel because they are sent paired up with each other.
Hope this helps,

SOURCE: hi,my Bravia started to have color stripes on 1/2

T-Con board is part of lcd panel and lcd panel seems defective in your tv problem.
Call Sony/ Store if tv is still under warranty for cover or lcd panel replacement would cost you 80% of new tv price.

How to use PIP show another channel in TV mode

Dear Ariesky

Your TV does not support this. Normally when SONY refers to PIP, they mean you can display another analogue ( CVBS - RGB ) or Digital ( HDMI ) input simultaneously. They do not mean you can dislay two normal RF channels together, this would require a second tuner, which this set does not have.

My Rca 52 inch has lost color But If I set the feature

PIP means the set uses either two tuners or a dual tuner--could be a issue with the tuner. If it has a swap feature in the PIP use it to see if color when tuner is switched from main to PIP tuner.

A possible way around the issue is to look to see if rear audio/video inputs have color---you could route signal from a box etc to one of those and BYPASS the problem if rear inputs do not have this problem(not likely they will).

Hi.The picture on my Sony KV32FQ75U has a green tint to it. When i select PIP the second picture with the same input is perfect.Is it possible to make this the main picture as when turning PIP off it...

odd problem--if PIP is normal remote should have a swap button--if the problem moves when you do that it is likely the main tuner--if issue only with one tuner the problem is there...............

Purchased 73 mitsubishi hdtv diamond series 1080 used....some ch are crystal clear while others just 2 or3 have white or colored spots. i dont have a cable box or any receivers, boxes hooked up to...

First: an old adage with TV sets of all kinds is the set is not smart enough to know what channel you are on---problems only on a few channels usually are not the set.

The only place where this is not the case is a group of several adjacent channels like 2-6 having this could mean a problem with the low band in the set's tuner--a bad tuner.

Most of these large Mitsubishi sets have PIP or picture in picture--the remote will have a swap button--engage it and see if the PIP has the same issue----if not the set uses 2 tuners and one is bad.

A cable box would allow you to instantly get around that by going into the rear audio/video jacks.

I have a sony (model KP61V75) a split screen came on (two pictures) and I cannot figure out how to get it back to one screen. Im going crazy!

Some television remote controls have a PIP OFF button, while others only have a PIP button that needs to be pressed repeatedly until the PIP/Twin-View window disappears.


  • Some Sony rear projection televisions have a FLASH FOCUS button that will turn off the PIP/Twin-View feature.

  • Some Sony universal remote controls, if programmed to operate a Sony TV, can disable the PIP/Twin-View feature by pressing the REC or ENT button.

  • If the original TV remote control is not available or is not functioning properly, auto programming the television tuner orperforming a power reset may deactivate the PIP/Twin-View feature.

  • If pressing the appropriate buttons on the TV remote control does not work, then the PIP/Twin-View window might be from a two-tuner cable or satellite set-top box. If this is the case, use the remote control provided with the set-top box to remove the PIP/Twin-View window.

Screen looks like a picture negative, PIP works fine, sound fine

Sony's have dual tuning systems to allow for the separate PIP channel. The common problem on the Sony's is the circuit board and tuning module connections go bad. It is likely that the connections on the board or module were already in the decayed process and moving it just accelerated the issues that were inevitable.

The quick fix is to swap the PIP over to the main picture or to bus the antennae signal to the antennae B terminal thus bypassing the bad tuner module.

The recommended fix action is to have someone with soldering skills to remove the chassis, and locate all the cold and cracked solder joints, especially near the tuning modules. If this does not take care of the problem, the tuning modules will need to be removed for re-soldering on the actual tuner modules.

If none of the above works, then you can always use the audio/video outputs of a cable box or vcr to the a/v jacks of the tv, thus bypassing both tuners in the tv.

Ilo problem

What I hear you saying is that your main television tuner shows lines only while the PIP is functioning properly. The PIP works by using a separate tuner from the main tuner of your television (like a vcr tuner). Since the PIP works then it appears that your main tv tuner is not working anymore. It will probably have to be replaced. I recommend looking at our online technician list for a professional near you.

Good luck :)
