Hate to disagree, but the tech asst. dept. said to upgrade to a larger fuse on certain models of flat screen crt 32 &36 inch models. We factory servicers first tried a 6.5 amp but a few came back, so we went to a 7 amp and that solved it. Those certain models draw alot of current to run the tube and it sometimes peaks very close to the original fuse's value. I agree not to go to any higher amperage but 7/10ths of an amp will stil provide safety within the set. Good luck, Russmann.

The original fuse in a Panasonic is a 6.3 AMP fuse. NEVER EVER use a larger fuse then the set is designed for. The thermistor is bad but, please only use a 6.3 amp fuse. Using a 7 AMP fuse as Patagonia suggested is downright a possible hazzard!

    I have read NO factory updates for any Panasonic model that states to use a larger fuse. The fuse goes at turn on due to the inrush current drawn by the thermistor/degauser on these units. The same happens with some Sony and Samsung CRT sets. Now changing the thermistor to a slightly higher resistance is the better choice so the degauser wont pull so much current at turn on. This is the ONLY fix that should be done period. Now if you want to take the chance and use a larger fuse on your repairs then do it and take the responsibility otherwise never advise the novice to re-engineer his/hers TV and possibly risk the chance of a fire!

You will need to have the switch replaced. If you are a handyman, it is possible to do it yourself It only involves un-soldering four contact points and re-soldering in the new switch. But be sure you use the same type of switch, or you may not be able to make the replacement one fit into the holes on the PC board. Don't forget to rate this answer.

Is the button broken? More likely, the thermistor and main fuse need replaced. The fuse should be upgraded to a 7 amp GMA.

Just got a 2nd hand TV model CT-90119 and need to know how to tune tv in for Playstation2 and is there an instruction manual available to download for free? Sam


Most likely you need the RF adaptor that the cable from PS2 plugs into before connecting to TV. There is an automatic switch that shifts the display from "TV" to "Game" when the game console is turned on. Tune TV to channel 3 or 4.

Where is the eye for the remote on the TV????


Hi, remote sensor is located behind the front screen, if the remote doesn`t work as well (you didn`t say so I`m assuming it doesn`t) then you either have bad tact switches on the control board (the buttons on the front of the set) or the 5 volt line to the control board is missing, video-tek

LG CT-29K30EX 29" TV plugged


LG CT-29K30EX 29" TV - We have the same symptoms as described. If you are a person who is not afraid of opening the back cover of your TV and replacing parts inside. this tip is for you. Contact a service person if your not 100% sure. Its actually easy, it involves replacing a small capacitor in the power supply section. You don't need to troubleshoot coz i've done that for you for free. Find this capacitor in the power supply. C801 with a value of 100uf / 35V. De solder and replaced it with the same value or a much higher Voltage rating e.g. 50V. Done! your T.V. is alive again. - Rey Tilles - New Zealand
