Problem with a Hyundai HQP421 HR Plasma TV

Powers up, image & sound are ok, but after 1 minute or so (this summer it was around 20 seconds), it shuts down suddently. I have to wait around 5mn to make tv power up again. Opening the back panel does not show anything suspect, except 2 big 400V capacitors on the main power board that are slightly bulged, but not leaking. Any idea welcome.

Tv shutting off then comes on


your lamp is going out, they last around 2 years, on the average, this is easily replaced by you, door is on the right side of the tv, you can take the lamp out, if it has a bubble on it, it is getting ready to go out

Projection TV keeps shutting down


Good Day;

Sounds like you have a bad green picture tube that has failed. To check this out; remove front speaker grill, remove small panel, you will see three CRT's (pictue tubes) sticking down, remove the little board on the middle tube then restore power. If TV stays on more then likely the CRT is bad but not always the driver on board could also be bad, check voltages.

Good Luck, big IRISH.

Sony KV 20S40 20" tv flutters, reduces in size and then shuts off


The set most probably has cracked solder joints in one of the deflection circuits, which is pretty common. The picture tube and major components are fine. A good tech can quickly resolder the main board and that should not cost too much. If your set came into my shop I would charge about $50 but ask around, the shops in your area will vary.

Hyundai 32" LCD displaying "invalid service "on some HD Staions Have just purchased a Hyundai 32" LCD Model CB-L3236LCD. Locallly I have Channel Prime HD and then Prime1, Prime2 and Prime3 which may or may not have differing programs to Prime HD ( I imagine in the future they will). Problem is on Prime 1,2,3 I either get a flash of the program then it returns to a blank screen with a blue box jumping all over the screen with "Invalid Service" written inside the box. Occassionally I may get a great reception on these stations but the Invalid Service box still appears. I can have a reception on Prime 1 say ( with Invalid Box0 and a blank screen on 2 and 3 with the invalid box. Very random it appears but common thread is the "Invalid Box". I only experience this with the Prime 1,2,3 Stations. I have a an older masthead amplifier booster system and I am about 5 kilometers line of sight from the Prime translator . I have a Panasonic 52" LCD as my main set which experiences no problems and have tried the Hyundai 32" on the aerial outlet which supplies the Panasonic in event the problem was due to a weaker signal at the Hyundai's normal location BUT I still have the Invalid Service problem with Prime 1,2,3. I went back to the store of purchase and tried their display set ( running on 'rabbit ears' aerial and less than one kilometre from the translator and the same problem existed on that set with Prie 1,2,3 only Anyone have any solution to this problem. Any software upgrades available for these models? Thanks in advance for any replies
