No colour at colour TV if useful 8823CPNG IC for it?

Check and replace the chroma IC. Before replacing it, re solder all the solder terminals to this IC, by applying a little more fresh solder to each terminals.

dear mr newk

i study ur problem carefully i got that u have a big problem....

 

i have a solution of u r problem...

actully u have problem with u r circuit board...ok

 

there is a colour code ic which is responsible for all colour effect on ur telivision.

u r colour ic is not working properly...

just u have to do is to change ur colour ic on ur circuit board..

i m 100% sure that u r problem will be solved...

 

best regards & best of luck..

 

this means your tv has a intermitent problem when the clour ic gets heated up it starts to give you green..so therefore you need to take your tv to a tech to have it repair by replacing the colour ic. good luck.

Good day!!!


if your TV is LCD it could be the T-con board...

if your TV is projection CRT type it could be the convergence I.C STK #####....

if your TV is DLP projection it could be the color wheel...

if you need specific answer please state the brand and model of your TV..


Thanks for using fixya,,....

5 supply Volt missing in IC TDA 11105ps/N3 used in beston tv

Hello
Your TVs red colour output section has the trouble. There is no red output at the red cathode of the picture tube. The red, green, and blue output sections are on the picture tube base board. In some Philips model, these will be consists of transistors, and some has an IC or Tree ICs for three colour output used. You just open your TV, measure the voltages at these three cahodes. There will be markings on the printed circuit board for these cathodes marked as [Rk,Bk and Gk].
In your TVs case the voltage at the Rk marked pin will be higher that the other two cathodes. This can be caused by an open drive transistor or an Ic whichever may ysed there. If it is transistor, just replace it with a same type and number, as in the ace of ICs the related Ic, must be replaced. If only one Ic is uded for red, green and blue outputs, that Ic must be replaced.
If you need any more assistance, feel free to get me through Fixya. Ok.

Hello
If you see the picture in yellow colour, means that there is no blue colour output from the video drive section in your tv, Yello is the mixtrure colour of red and green. Green is actualy there. blue colour is absent.
To detect this fault, you must open your tv. Just look in to the video output section, can be located at the picture tube base card, which is plughed into it diretly. See for any loose soldering points there. Check whether transisotors are used for red, green and blue output stages, or an Ic or three seperate Ics are used for this purpose. Anyway, blue catode of your picture tube pin gets a hig voltage, and so the blue emission is absent. You just check the voltages at red,gree and blue catodes, at the respective picture tube pins, which can be taken at picture tube base card. All of these three pin voltages must be somewhat equal to each other. In your case, no voltage at blue cathode will be higher that the other two. Check for the reason. It may be due to an open video output transistor [blue], or an Ic, of one Ic if used for the three colour outputs. Check and replace the same, will rectify your problem. Ok
If you have andy difficulty, get it to me through Fixya. Ok

check colour ic .....
check chroma section....
check power supply related to chroma and colour ic..
set the pre set @ EHT....

give ur model no of tv..or processor ic no ..to any sony service station or electronic spare vendor toget the programmed memory ic...& REPLACE IT...

You need to use Aiwa Service Remote to enter in service mode and adjust service data for red and Blue drive of CRT.
Do you have that remote and service data reference book of Aiwa tv ?
