HI Uday,
If you could select channel using the front button then the remote may have problem. Try open up and check if there is any broken circuit track (remote control may have dropped on the floor) and if all found to be good then i suggest that you get a new remote control.

Jestine, my 14" akira tv has no picture. If i tune it to ordinary channel, it'll show as if it is on AV. It has no raster. What could be the problem?

Hi Inem,
try check the G2 voltage and make sure it has about 250 to 300vdc.

Hi Jestine
I have a Samsung TXJ2767 27" CRT TV. When you turn it on, the green power light flashes an number of times but does not stay on. The sound is good but there is no picture. It used to take about 5 minutes to get a picture, it got worse (longer time) and now there is no picture. I looked inside at the larger capacitors. One had an end that was rounded. I replaced it but it still has no picture. I also looked for cold solder joints but did not see any that looked that bad. Any other suggestions? Thanks.

HI Art,
Try check the CRT area for dry joints. You may also gently tap on the board using the handle of the screw driver to see if there is any improvement. Make sure also there is B+ voltage reaching to one of the flyback transformer pin.

Hi
I have a prolem with my smsung TV, that is the color is only normal at the center of the screen, at the sides it changes (exemple: the red becomes bleu and inversly)
Thanks

HI Sadou,
Do you mean color patches problem? If yes then suspect a bad crt tube or the posistor circuit have problem.

HI AZALE,
You mean the tv problem was in standby mode? If yes then have you check whether the main power supply power ic is getting any dc supply voltage or not?

Photos which best describes the problem I have with the Samsung 52 "LCD 1080hp. bar or something, that at least I call a picture appeared on the screen with a strange resolution, and the effect a little reminiscent of" shadow "or" spirit "moving from the left side of the screen to the bottom right. For any feedback undying thanks.
Yours!

HI Szikagier,
Thanks for the photo. It seems that the problem could cause by bad driver ic and failed TAB bonding. The only solution is to replace the LCD panel.

Hi Jholen,
Yes there is a possibility the cpu have problem. Sometime a corrupted eeprom data could cause such problem too. If either one -remote or the control malfunction then chances that one particular have problem but now the case was both circuit also not functioning and the CPU is the one that control both circuit. Make sure no broken tracks and dry joints in the cpu, remote and the control panel area.

HI Jholen,
You can try desolder that pin and power on. Cpu part is hard to find. Try utsource.net
